    ANTENNA ARRANGEMENT Technical FieldThe present invention relates to an antenna arrangement for mobile communication, which antenna arrangement comprises an antenna feedingnetwork, an electrically conductive reflector and at least one radiating elementarranged on the reflector, wherein the antenna feeding network comprises at least one coaxial line.
    Background of the InventionMulti-radiator antennas are frequently used in for example cellular networks. Such multi-radiator antennas comprise a number of radiating antenna elements forexample in the form of dipoles for sending or receiving signals, an antenna feedingnetwork and an electrically conductive reflector. The antenna feeding networkdistributes the signal from a common coaxial connector to the radiators when theantenna is transmitting and combines the signals from the radiators and feedsthem to the coaxial connector when receiving. A possible implementation of such a feeding network is shown in figure 1. ln such a network, if the splitters/combiners consist ofjust one junction between 3different 50 ohm lines, impedance match would not be maintained, and theimpedance seen from each port would be 25 ohm instead of 50 ohm. Thereforethe splitter/combiner usually also includes an impedance transformation circuitwhich maintains 50 ohm impedance at all ports.
    A person skilled in the art would recognize that the feeding is fully reciprocal in thesense that transmission and reception can be treated in the same way, and tosimply the description of this invention only the transmission case is describedbelow.
    The antenna feeding network may comprise a plurality of parallel substantially airfilled coaxial lines, each coaxial line comprising a central inner conductor at leastpartly surrounded by an outer conductor with insulating air in between. The coaxiallines and the reflector may be formed integrally with each other. The splitting may be done via crossover connections between inner conductors of adjacent coaxial 2 lines. ln order to preserve the characteristic impedance, the lines connecting to theCrossover element include impedance matching structures. The substantially airfilled coaxial lines may be provided with a dielectric element to provide a phaseshifting arrangement. The phase shift is achieved by moving the dielectric elementthat is located between the inner conductor and the outer conductor of a coaxialline. lf the dielectric element is moved in such a way that the outer conductor willbe more filled with dielectric material, the phase shift will increase.WO2009/041896 discloses an antenna arrangement provided with an adjustabledifferential phase shifter using such a movable dielectric element.
    The radiating element is typically a dipole. A dipole usually may consist of tworadiating parts having an electrical length of approximately one quarter of awavelength at the operating frequency and extending essentially in plane parallelwith the antenna reflector, and positioned approximately at a distance equivalentto one quarter of a wavelength at the operating frequency. The radiating parts arefed in counter-phase. Such a feeding is achieved by using a balanced-unbalancedtransformer, also called a balun. ln a dipole, it is often convenient to also use thebalun as a mechanical support of the two radiating parts. The balun is often also used as an impedance matching element.
    The balun consists of a body part and a coupling element which can also be seenas a conductor positioned in the centre of a cylindrical hole in the body part. Thebalun coupling element is electrically connected at one end to one of the radiatingelements, and at the other end to a feeding line inner conductor.
    The body part is usually connected to feeding line outer conductor and to the antenna reflector.
    The connection between the radiating element and one of the inner conductorsmay be achieved using for example a screwjoint. Thus, direct contact between theelectrically conductive coupling element of the radiating element and an electricallyconductive portion of the inner conductor is established. Such an arrangement hasthe disadvantage that it may be difficult and time consuming to assemble ormanufacture since a screwed connection may be difficult to achieve in the verylimited space available inside the outer conductor. Also, the screw and the 3 coupling element are often inserted from opposite sides of the antenna whichmakes assembly difficult. Another disadvantage with the screw joint is that it mayintroduce passive intermoduiation (PIM). Due to the small dimensions of thecoupling element of the radiating element, the screwjoint also needs to be of smalldimensions, which makes it particularly difficult to achieve a connection which issufficiently firm to avoid PIM.
    Summary of the InventionAn object of the present invention is to overcome at least some of thedisadvantages of the prior art described above.
    These and other objects are achieved by the present invention by means of anantenna arrangement and a method for manufacturing such an antennaarrangement according to the independent claims. Preferred embodiments aredefined in the dependent claims.
    According to a first aspect of the invention, an antenna arrangement comprising anantenna feeding network, an electrically conductive reflector and at least oneradiating element arranged on said reflector is provided. The antenna feedingnetwork comprises at least one substantially air filled coaxial line, each coaxial linecomprising a central inner conductor and an elongated outer conductor at leastpartly surrounding the central inner conductor, wherein the at least one radiating element and at least one coaxial line are configured to interconnect indirectly. ln other words, one or a plurality of radiating elements, for example dipoles, areconfigured to connect electrically in an indirect manner with at least one coaxial line to achieve electrical connection for signals to/from the radiating element(s).
    The invention is based on the insight that an antenna arrangement which is easyto assemble, yet provides high performance and low passive intermodulation, maybe achieved by indirectly interconnecting at least one radiating element with acorresponding coaxial line, instead of connecting them galvanically. Such anindirect interconnection, i.e. capacitive or inductive interconnection or a combination of the two, between the radiating elements and the coaxial lines may 4 provide an interconnection which may not suffer from the disadvantages associated with mechanical/galvanical connections discussed above.
    Herein the word indirectly means that electrically conductive material of theradiating elements and coaxiai lines are not in direct physical contact with eachother, i.e. are non-galvanically connected. lndirectly thus means an inductivecoupling, a capacitive coupling or a combination of the two. lt is understood that coaxiai line refers to an arrangement comprising an innerconductor and an outer conductor with insulating or dielectric material or gas therebetween, where the outer conductor is coaxiai with the inner conductor in thesense that it completely or substantially surrounds the inner conductor. Thus, theouter conductor does not necessarily have to surround the inner conductorcompletely, but may be provided with openings or slots, which slots may evenextend along the full length of the outer conductor.
    As described above, the at least one coaxiai line is substantially air filled in thesense that each coaxiai line is provided with air between the inner and outerconductors. The air between the inner and outer conductors thus replaces thedielectric often found in coaxiai cables. ln embodiments described below, theantenna feeding network may be provided with further components inside theouter conductor such as connector elements, support elements and dielectricelements which also occupies part of the space inside the outer conductor whichwould othenNise be filled with air. The coaxiai line is thus substantially, but notcompletely, airfilled in these embodiments. ln embodiments, the at least one radiating element and at least one coaxiai lineare configured to interconnect indirectly in the sense that the at least one radiatingelement and a central inner conductor of the at least one coaxiai line areconfigured to interconnect indirectly, and/or in the sense that the at least oneradiating element and an outer conductor of the at least one coaxiai line areconfigured to interconnect indirectly. ln one such embodiment, the at least oneradiating element and a central inner conductor of the at least one coaxiai line areconfigured to interconnect indirectly, while the radiating element and an outer 5 conductor of the at least one coaxial line are configured to interconnectgalvanically. ln embodiments, the at least one radiating element comprises a coupling elementfor interconnecting with the at least one central inner conductor. The indirectconnection between the radiating element and the coaxial line may consist of anindirect connection between the coupling device and the inner conductor of thecoaxial line, an indirect connection between the radiating element body and the coaxial line outer conductor, or a combination of both.
    The at least one radiating element may each comprise two or more radiating partswhich may extend essentially in plane parallel with the antenna reflector. Theradiating parts may have an electrical length of approximately one quarter of awavelength at the operating frequency and be positioned approximately at adistance equivalent to one quarter of a wavelength at the operating frequency. Theradiating parts may be fed in counter-phase. Such a feeding may be achieved byusing a balanced-unbalanced transformer, also called a balun, which may alsoform a mechanical support for the two radiating parts. The balun may also be usedas an impedance matching element. The balun may consist of a body part and thecoupling element which is positioned in the centre of a cylindrical hole in the bodypart. The body part may be connected to outer conductor and to the antennareflector.
    The indirect interconnection may be achieved by means of at least one insulatinglayer. The insulating layer may be arranged on the coupling element and/or onportions of the at least one inner conductor. The insulating layer may be providedby means of a coating on the coupling element and/or on the at least one innerconductor, the coating comprising at least one polymer and/or oxide material.Alternatively, the insulating layer may be a separate component of a non-conductive material placed between the coupling element and the at least one inner conductor. ln embodiments, the at least one radiating element comprises a coupling elementwhich comprises a free end portion, wherein the coupling element is configured to 6 interconnect with a central inner conductor of the at least one coaxial line via thefree end portion. The at least one inner conductor may comprise a receiving cavityor through hole configured to receive the free end portion. ln these embodiments,the insulating layer may be provided on the free end portion and/or in said cavityor through hole. The free end portion may be conically shaped. Alternatively, thefree end portion may be cylindrically shaped. The cavity or through hole may alsobe conically or cylindrically shaped, preferably having the same shape as the freeend portion such that the free end portion fits tightly in the cavity or through hole.Such a cavity or through hole thus has the function to help securing the position ofthe free end portion and thus the coupling element in a plane parallel to a planedefined by the electrically conductive reflector. As described above, the free endportion may be conically shaped, e.g. formed as an inverted cone. An invertedcone may simplify the connection by making it easier to guide the connectorelement into the cavity or through hole of the inner conductor. The receiving cavityor through hole may extend partially or all the way through the at least one innerconductor. ln embodiments, the antenna arrangement comprises a snap on mechanism,where the snap on mechanism comprises a snap on portion integrally arranged onthe coupling element, at least in proximity of the free end portion, and acomplementary snap on portion arranged on the inner conductor.
    The coupling element may comprise a conductor line portion, where the free endportion is formed with a step at an end of the conductor line portion. The free endportion or the step may have a greater diameter than the conductor line portion.The step may form the snap on portion of the coupling element.
    The snap on mechanism may comprise a snap on bracket comprising thecomplementary snap on portion. The snap on bracket may be configured to besnapped around the at least one of the inner conductors. The snap on bracketmay be made of a plastic material.
    Although it has been described to use the step as snap on portion, the snap onportion may be embodied in another way such as for example a protrusion, a 7 circumferential protrusion, a notch or a groove being arranged on the coupling conductor element.
    The snap on mechanism may improve handling when connecting the radiatingelements to the inner conductors. ln embodiments, the snap on mechanism is releasabiy attachable. ln an alternative embodiment, the snap on mechanism comprises a dielectricsupport element configured to hold and at least partially surround the at least oneof the inner conductors, wherein the dielectric support element comprises thecomplementary snap on portion. The dielectric support element may be configuredto hold the inner conductor in position inside the outer conductor, and may bemade of a plastic material.
    The complementary snap on portion may be realized in the form of snap on fingersor extensions, which are configured to engage the snap on portion when the freeend portion is in an engaged position. The engaged position may be when the freeend portion is positioned on or in the inner conductor in order to provide an indirectelectrical connection there between.
    The embodiments described above may be combined in any way. ln embodiments, the radiator body has an insulating layer on its surface which isclose to the coaxial line outer conductor, alternatively the coaxial line has aninsulating layer where the radiator body is located, or an insulating film is insertedbetween the radiator body and the coaxial line outer conductor in order to createan indirect connection between the radiator body and the coaxial line outerconductor.
    According to a second aspect of the invention, a method for manufacturing anantenna arrangement for mobile communication is provided. The methodcomprises providing an antenna feeding network comprising at least onesubstantially air filled coaxial line, each comprising a central inner conductor andan elongated outer conductor surrounding the central inner conductor, providing at 8 least one radiating element, and interconnecting the radiating element and the at least one coaxial line indirectly. ln embodiments of the method according to the second aspect of the invention,the step of interconnecting comprises interconnecting the radiating element andthe at least one central inner conductor of the at least one coaxial line indirectly,and/or interconnecting the radiating element and the outer conductor of the atleast one coaxial line indirectly. ln one such embodiment, the step ofinterconnecting comprises interconnecting the radiating element and the at leastone central inner conductor of the at least one coaxial line indirectly, andinterconnecting the radiating element and the outer conductor of the at least one coaxial line galvanically.
    The description above of embodiments also applies to embodiments of the second aspect of the invention in an analogous manner.

    Detailed Description of Preferred EmbodimentsFigure 1 schematically illustrates an antenna arrangement 1 comprising an antenna feeding network 2, an electrically conductive ref|ector 4, which is shownschematically in figure 1, and a plurality of radiating elements 6. The radiatingelements 6 may be dipoles.
    The antenna feeding network 2 connects a coaxial connector 10 to the plurality ofradiating elements 6 via a plurality of lines 14, 15, which may be coaxial lines,which are schematically illustrated in figure 1. The signal to/from the connector 10is split/combined using, in this example, three stages of splitters/combiners 12.
    Turning now to figure 2, which illustrates an antenna arrangement 1 in aperspective view, the antenna arrangement 1 comprises the electrically conductiveref|ector 4 and the radiating elements 6.
    The electrically conductive ref|ector 4 comprises a front side 17, where the radiating elements 6 are mounted and a back side 19.
    Figure 2 shows a first coaxial line 20a which comprises a first central innerconductor 14a, an elongated outer conductor 15a forming a cavity or compartmentaround the central inner conductor, and a corresponding second coaxial line 20bhaving a second inner conductor 14b and an elongated outer conductor 15b. Theouter conductors 15a, 15b have square cross sections and are formed integrallyand in parallel to form a self-supporting structure. The wall which separates thecoaxial lines 20a, 20b constitute vertical parts of the outer conductors 15a, 15b ofboth lines. The first and second outer conductors 15a, 15b are formed integrally with the reflector 4 in the sense that the upper and lower walls of the outerconductors are formed by the front side 17 and the back side 19 of the reflector, respectively.
    Although the first and second inner conductors 14a, 14b are illustrated asneighbouring inner conductors they may actually be further apart thus having one or more coaxial lines, or empty cavities or compartments, in between. ln figure 2, not all longitudinal channels or outer conductors are illustrated withinner conductors. lt is however clear that they may comprise such inner conductors.
    Each of the radiating elements 6 is configured to be electrically connected to at least one of the inner conductors 14 via a coupling element 24 (c.f. figure 3).
    The front side 17 of the reflector may comprise at least one opening 40 for theinstallation of a connector device 8. The opening 40 extends over the twoneighbouring coaxial lines 20a, 20b so that the connector device 8 can engage theinner conductors 14a-b.
    Figure 3 illustrates a perspective view onto a cross section cut through the middleof one of the radiating elements 6 in longitudinal direction of antenna arrangement.Figure 3 also illustrates how the radiating element 6 is connected to one of theinner conductors 14. The radiating element 6 comprises a coupling element 24having a conductor line portion 46 and a free end portion 48 at an end of theconductor line portion 46. The coupling conductor element 24 extends through theat least one opening 28 in the electrically conductive reflector 4 into a cavity orthrough hole 36 formed in the inner conductor 14.
    The cavity or through hole 36 and the free end portion 48 of the couplingconductor element 24 are both conically shaped having corresponding diameterand rise to achieve a tight fit. The cavity or through hole 36 extends through theentire inner conductor 14, but may in other embodiments only extend partially intothe inner conductor 14. 11 The coupling between the coupling element 24 and the inner conductor 14 iseither capacitive, inductive or a combination therefore. This is achieved byproviding a thin insulating layer on at least the free end portion 48 of the couplingelement. ln other embodiments, the cavity or through hole 36 comprises a thininsulating layer, while the free end portion does not. The insulating layer may havethickness of less than 50 um, such as from 1um to 20 um, such as from 5 um to15 um, such as from 8 um to 12 um. ln other embodiments, both the free endportion 48 and the cavity or through hole 36 comprise a thin insulating layer. Thethin insulating layer could be provided by applying a thin layer of a polymermaterial, or by having a thin oxide layer, or by some other provisions applying an isolating layer.
    The radiating elements 6 each comprise four identical radiating parts 6a-d forminga dipole. The radiating parts extend essentially in plane parallel with the antennareflector. The radiating parts are fed using a balanced-unbalanced transformer 6e,also called a balun, which also forms a mechanical support for the radiating parts.As is further illustrated in figure 3, the balun comprises a body part 6e' and thecoupling element 24 which is positioned in the centre of a cylindrical hole in thebody part. The body part 6e' is connected to the outer conductor and to the antenna reflector.
    Figure 4 illustrates another perspective cross sectional view of the connectionbetween the radiating element 6 and the inner conductor 14. The cross section iscut through the connection. The coupling element 24 and its enlarged free endportion 48 are shown. The free end portion 48 is conically inverted shaped andcomprises a step 35 between the free end portion 48 and the conductor lineportion 46. The free end portion 48 has a greater diameter than the conductor lineportion 46.
    Although the free end portion 48 has a conically inverted shaped it is conceivablethat it has another shape such as cylindrical, cubical, etc. The shape of the cavityor through hole 36 may be adapted accordingly. 12 Figure 5 schematically illustrates the inner conductor 14 and the couplingconductor element 24 engaged in the cavity or through hole 36. As can be seen,the inner conductor 14 has a slightly greater diameter where the cavity or throughhole 36 is shaped. This may be done for example for improved stability and/or ahigher capacity of the indirect electric connection. The step 35 formed between the conductor line 46 and the enlarged free end portion 48 is also shown.
    Figure 6 schematically illustrates a cross section view of parts of an antennaarrangement which comprise a snap on mechanism. The snap on mechanism hasa snap on portion in the form of the step 35, which is integrally arranged on thecoupling element 24 (only partially shown in the figure), above the free end portion48, and a complementary snap on portion 49 arranged on the inner conductor 14.The complementary snap on portion 49 is formed as an edge of a dielectricsupport element 50 that is used to engage with and hold the inner conductor 14 inposition within the outer conductor. The support element 50 is made from a plasticmaterial which is slightly flexible which causes the opening in the spacer to widenslightly when the coupling element is pushed into the cavity or through hole of theinner conductor. After the coupling element has been pushed down, the edge/snapon portion 49 prevents it from accidentally leaving the cavity or through hole. lnother embodiments, the complementary snap on portion is formed on a separate component which is not a dielectric support element.
    The description above and the appended drawings are to be considered as non-limiting examples of the invention. The person skilled in the art realizes thatseveral changes and modifications may be made within the scope of the invention.For example, the number of coaxial lines may be varied and the number ofradiators/dipoles may be varied. Furthermore, the shape of the coupling elementand inner conductors and the placement of the insulating layer or coating may bevaried. Furthermore, the reflector does not necessarily need to be formedintegrally with the coaxial lines, but may on the contrary be a separate element.
    The scope of protection is determined by the appended patent claims.
