Definitions
- Antenna in particular mobile radio antenna
- the invention relates to an antenna, in particular mobile radio antenna according to the preamble of claim 1.
- Mobile radio antennas of today's generation usually comprise a one, two or more columnar antenna array, each with an associated reflector, which is vertically or predominantly vertically aligned.
- the respective radiator and radiator devices for transmitting and / or receiving the signals are arranged one above the other.
- These radiator devices can be linearly polarized radiator devices or, for example, dual-polarized radiator devices, which are preferably aligned at an angle of + 45 ° with respect to the horizontal or vertical. In that regard, is often spoken of X-polarized radiator devices.
- the antenna can be used as Mono-band antenna, be designed as a dual-band antenna or as a multi-band antenna, which thus can radiate and / or receive in multiple frequency bands.
- passive components may also be housed, such as filters, adjustment elements such as phase shifter for adjusting the down-tilt angle, various cabling, etc.
- a so-called envelope reflector is often used, which is also designed in cross-section also at least U-shaped or approximately U-shaped.
- This envelope reflector has a base plate, which is arranged at a distance below the reflectors in an envelope reflector support plane, wherein the reflector base plate at its two longitudinal sides in perpendicular to the envelope reflector support plane or at least transversely oriented side walls or Sidewalls passes. These side flanks often end in the area of the reflector side webs of the single or multi-column reflector arrangement.
- a radome covering the radiation devices and the single- or multi-column reflectors is then placed on these free edges of the side webs of the envelope-reflector support structure and glued or screwed to the sides.
- passive component and / or distributor level which is sometimes also referred to as a passive component and / or distributor space
- additional active components can then be accommodated on the actual rear side of the envelope / reflector support structure opposite the radiators.
- amplifier groups such as amplifier groups, a remote radio head etc.
- the object of the present invention is to provide an improved antenna, in particular a mobile radio antenna, which has improved mechanical and electrical properties.
- the antenna according to the invention is preferably a so-called active antenna with active components such as a remote radio head.
- it is an antenna or mobile radio antenna, which has a highly compact design, that is, has a high packing density.
- the antenna is clearly structured and structured by its structure, since it initially comprises an uppermost radiator and reflector plane, a passive component plane located underneath, to which a so-called active component plane is then connected again underneath.
- the at least one-column antenna for the radiators comprises a reflector, which is part of a so-called overall reflector and is formed as such in one piece.
- This is a preferably cohesive structure in which the conductive overall reflector formed in this way is designed as a stamped-bent sheet metal part or, for example, as a continuous cast pressed part.
- the actual, the radiator elements bearing reflector usually passes over lateral, transverse to the reflector plane in the steel direction projecting side bars and then ultimately in the backward side extending Schirmungscind that extends beyond the located on the back of the actual reflector passive component level addition.
- all passive components and the further devices provided in this plane or in this space such as, for example, cabling, which are provided on the rear side of the actual reflector which receives the radiator elements, are further shielded by these side wall webs.
- the radiators sit on the base portion of the overall reflector on the outside, ie the side which is formed opposite to the side webs of the overall reflector.
- the passive components are then in a first passive component and / or distribution space. accommodated (at least for the most part), which then adjoins an active component space on the side facing away from the emitters of this component and / or distributor space via a holding and mounting plane thus formed, in which especially the active components can be mounted and housed.
- the overall reflector thus formed offers optimal shielding for the components accommodated therein, since the side webs of the overall reflector thus formed are extended beyond the abovementioned holding and mounting plane in the direction opposite to the radiators, so that not only the passive components housed inside the overall reflector and / or the wiring used for the distribution are optimally shielded, but also the components adjoining the holding and mounting plane, as in known solutions according to the prior art.
- the overall reflector explained above including the actual reflector section holding the spotlight and the associated passive component and / or distributor space
- a radome can be covered by means of a radome.
- the overall reflector described above with the corresponding components and the mounted radiators can be pushed into a corresponding radome on the face side, which is completely closed in the circumferential direction apart from recesses discussed below.
- This also gives an optimal protective effect. But this also ensures optimal Tension between the radome and the total reflector achieved, resulting in a further improved overall support structure, whereby the entire support structure can absorb and support even higher loads, and this with a comparatively thin material design of the actual overall reflector and / or Radom.
- the wind forces that can act, for example, on the radome, optimally recorded and the antenna are supported accordingly.
- the radome is slidable onto the overall reflector in the axial direction in such a way that, among other things, the radome is preferably in the region of the holding and mounting plane for the active components and / or at an offset plane, preferably approximately can support at the level of the reflector portion on which the radiators are held and mounted.
- material-thickening elevations, beads, etc. may be formed on the inside of the radome, which also rest on a corresponding bearing surface of the overall reflector and also support themselves here.
- the illustrated antenna and in particular the described mobile radio antenna is used not only for a single-column, but for example for a two- or multi-column antenna array. Because in such an embodiment, it is preferably provided that the two or more individual reflectors extending parallel to one another, each of which forms an antenna column, are likewise formed in one piece, that is to say a part of the overall reflector. represent sector. Also located between the two antenna gaps and usually provided from the reflector plane vertically or transversely rising reflector side bar is part of the aforementioned total reflector, which can be designed and manufactured as punched-bent part or, for example, as a continuous casting part.
- the present invention has clear advantages, for example: since the at least one or at least a plurality of reflector sections provided in each case for an antenna column, including in the form of an overall reflector, are formed in one piece, intermodulation products are avoided. In addition, an overall improved shielding is achieved, on the antenna rear side for the passive components and components provided there in a first plane (space) and the active components in a second plane (space) below,
- the entire support structure is improved and can take significantly more load and support at comparable formed to the prior art material thicknesses, which conversely also means that in the support of comparable weights and loads, the overall reflector structure formed thinner walls and thus the entire antenna is lighter .
- the improved support structure achieved in the invention is characterized by the composite of the overall reflector, for example in the form of a stamped bent part or in the form of a continuous casting part in conjunction with the radome, for example in the form of a GRP profile, which at least Has sections that are completely closed in the circumferential direction,
- the entire reflector with the associated antennas and the individual antenna assemblies can be easily pushed out of the radome during production and servicing, or pushed in the other direction. It proves to be particularly favorable if the antenna preferably has a plug connector in the region of the holding and / or mounting plane for the active components, which is offset in the direction of the emitter towards this plane in that the aforementioned total deflector can be inserted or pushed out into the radome which is circumferentially closed at least in certain sections over its axial length.

- both column or partial reflectors 10 'of the two antenna columns 8 form a common fixed, one-piece reflector structure.
- the two outer and the Webs 10a also pass on the radiation side of the reflector arrangement into an outwardly diverging connecting web 18, which then merges via a further bend 20 into a first shielding wall 19 extending more or less opposite to the emission direction R of the antenna arrangement.
- the mentioned connecting webs 18 and the bridge web 17 can be approximately the same height, i. preferably at the same height or at the same distance from the reflector plane RE (although this is not mandatory) and can be completely or predominantly aligned parallel to the reflector plane RE.

- This second shielding wall 27 is also integral with the overall reflector assembly 15, i. of the overall reflector 16.
- Such a construction creates a first receiving space 29 which lies on the rear side of the antenna gaps 8, ie on the rear side IIb of the column or partial reflectors 10 ', and into the region of the anchoring section 21 or the mounting plane ME is enough or enough.
- This first receiving space or area 29 forms a so-called first receiving level 29 ', which is also referred to below as passive component and / or distribution space 29 or passive component and / or distributor level 29', by the reflector with its specific Design is completely shielded.
- This level 29 'or this area or space 29 can therefore also be referred to in the broadest sense as the first or passive component and / or distribution space. that because here in addition to the first or passive components 129 (such as filters or, for example, phase shifter for a ⁇ provide a different down-tilt angle of the radiator), above all, a plurality of cables accommodated introduced and can be laid out what the energiser of individual radiator and radiator groups takes place.
- the first or passive components 129 such as filters or, for example, phase shifter for a ⁇ provide a different down-tilt angle of the radiator
- the radome 105 which forms part of the overall housing 5, is shown in a schematic, rather rearward, spatial representation.
- This radome which consists of a GRP profile and is permeable to electromagnetic radiation, usually comprises a front side 105a, below which the antenna columns with the radiators are provided.
- This front side 105a which can generally run relatively flat in the middle region and at least approximately parallel to the reflector planes RE, then merges on the longitudinal sides via an arc section 105b into side sections 105c which run more or less adjacent to the first shielding wall 19 and these cover to the outside.
- these side sections 105c of the radome 105 are dimensioned such that they extend as far as the lowermost boundary edge 27a of the second shielding wall 27, which is the most remote from the radiators bounded arched section 105d in order to form an inner wall section 105e on the mutually facing inner sides 27b of the second shielding wall 27.
- These inner wall sections 105e run on the side 22c facing away from the radiators (of the lateral web 22 'a lying farther away from the radiators) parallel to these lateral webs 22a, 22' a toward one another, forming a rear wall 105f.
- the rear side 105e of the radome 105 is formed, so that in principle the entire radome space 105g is enclosed.
- the inner wall section 105e runs parallel to the corresponding outer section 105d of the radome, specifically forming a pocket which is slot-shaped or groove-shaped in the embodiment shown in the longitudinal direction L of the radome and which is open towards the interior of the radome 105g.
- One of the recesses 31 is designed slot-like and extends in its longitudinal extent transversely to the longitudinal direction L of the antenna, preferably in the central region of the radome.
- a so-called plug interface 33 is formed (FIG. 2b), specifically in the form of a plug connector 133 with plug-in connectors 35 mounted therein, ie co-located, generally coaxial connectors. These sit in relation to the rear mounting area.
- ne ME corresponding to the rear side 105f of the radome 105) in the direction of individual reflectors 10 1 , that is recessed in the direction of the component receiving space 29, so that the actual connector interface plane KE does not project beyond the plane ME of the back of the rear wall 105 of the radome.
- the aforementioned plug connector strip 133 has an S- or Z-shaped contour 36 at its ends facing the edge regions of the antenna, with an outwardly-extending and then transversely aligned, i. parallel to the bottom web 22b of the anchoring portion 21 extending web 37. There, then, the connector strip 133 is firmly anchored, for example by means of screws and nuts.
- This overall design also has the significant advantage that, for example, an illustrated overall reflector arrangement 15 in the form of the explained overall reflector 16 with radiators 13 mounted thereon and, for example, in the passive component plane 29 ', i. the receiving space 29 Vietnamese passive components and the wiring provided here in the assembled state can be inserted axially into the radome 105, ie in the receiving space 105g in the radome 105th
- this torsionally rigid connection is connected to the overall reflector 16, whereby the total load that can accommodate the overall construction, including the weights of the individual components as well as the wind load attached to an antenna, etc., is significantly higher. as the individual components can be assumed on their own.
- the illustrated radome 105 is not only fixed on the rear side in the region of its slot-shaped and / or groove-shaped pocket 109 with the respective second shielding wall 27 engaging therein, and in particular application-rigid, but also in that the Inner side of the radome rests at least at a deviating second position on the overall reflector 16 and is supported.
- this support takes place in the area of the overhead arc section 105 b, at which the front side 105 a of the radome 105 merges into the side sections 105 c.
- a longitudinal elevation or a longitudinal bead 107 or the like may be formed internally for reinforcement, which rests, for example, on the outer connecting web 18 of the overall reflector 16.
- the training could also be such that, for example, the edge portion 20 between the outer VietnamesesStegen 18 abuts the inner wall 108 of the radome at the transition to the first Schirmungswand 19 of the overall reflector 16 and thereby leads to a second edition, whereby the entire Radom- construction is largely torsionally stiff connected to the skeletal overall reflector 16 therein.
- the width of the slot-shaped or groove-shaped pocket 109 is adapted to the material thickness of the shielding wall engaging therein, ie corresponds to the thickness of this shielding wall or is at least slightly wider. It can also be seen from the illustration according to FIG. 3 with a view of the rear side 105f of the radome 105 that in the lateral longitudinal region at intervals there are also further, generally bores, ie round recesses 39 introduced. These recesses 39 are located in the region of the U-shaped anchoring section 21 of the overall reflector 16.
- second or active components such as amplifier modules, remote radio heads, etc. can now be located in the second and / or active component level 41 ', that is accommodated in a so-called second or active component area or space 41.
- These second and / or active components 141 are significantly better shielded compared to conventional solutions, since the second shielding wall 27 protrudes in the direction of this second and / or active component region 41, ie in the rearward direction H via the mounting plane ME.
- laterally inserted screw connections 44 are provided for this purpose.
- screws 45 which engage in transverse alignment or perpendicular orientation to the mounting plane ME, ie also to the connector interface 33 through corresponding holes 22d ( Figure 4) in the lower web 22'a of the U-shaped anchoring portion 21, wherein respective nuts 46 are held in a rule by plastic holder lapping and twisting.
- plastic holders can be inserted from the outer sides into the U-shaped anchoring sections 21 and congruent at corresponding locations 4) can be positioned by means of a corresponding clamping seat with which the plastic holders with the integrated nuts are held. This is done before the corresponding pre-assembled total reflector 16 is inserted with the mounted first components 129 in the axial direction of the radome 105. Subsequently, only the corresponding screws 45 have to be screwed through the boring openings 39 into the aforementioned preassembled nuts 46, which are held in the correct position in the plastic holders. As a result, therefore, the second and / or active components can be grown on the rear side 105f of the radome 5.
- FIG. 5 a So that a good galvanic contact between the active components 141 and the overall reflector 16 is produced, as shown in FIG. 5 a in a detailed sectional view, a correspondingly larger-sized recess 39 is made in the radome, so that the abutment or support feet 43 of the active components 141 rest directly on the metal of the overall reflector 16 in the region of the side wall 22 'a which is more remote from the radiators and forms a galvanic contact.
- the contact side of the support legs 43 may have a greater transverse extent than the corresponding bore 39 in the radome, so that the contact surface of the support feet 43 rests directly on the electrically non-conductive radome.
- a sealing or insulating ring 48 is inserted, which is at least slightly elastic. As a result, sufficient clamping forces are permanently generated and maintained. receive.
- a further screw 47 is parallel to the support legs 43 introduced with the material of the radome 105 at the corresponding metal side bar 22 'a is held. Also, parallel to the first mentioned recesses 39, outwardly offset, generally smaller-diameter, further recesses 40 are provided, through which corresponding screws 47a with corresponding nuts 47b can be tightened in order to achieve the above-described effect.
- the screw connection 47 and the respective support feet 43 arranged adjacent thereto are arranged side by side with the screws 45 passing through the support feet 43, and the screw connection 47 of the shielding wall 27 is arranged transversely and in particular perpendicular to the longitudinal direction of the antenna is positioned closer.
- the support feet 43 and / or the support feet 43 passing through screws 45 and the additional screw 47 in question can be arranged one behind the other in the longitudinal direction of the reflector, ie parallel to the adjacent Schirmungswand 27th
- Figure 5b shows a variant in which the reflector, the radome and the active components together with a screw, ie in the embodiment shown with the screws in question 45 are connected to each other.
- the antenna feet 43 have a support section 43 'projecting beyond a small amount parallel to the screws 45 in the direction of the radiator element, which penetrates or dips into a corresponding bore or passage opening 105h in the rear side 105f of the radome.
- the axial height parallel to the screw 45 of this support section 43 1 corresponds to the material thickness of the radome 105 or the rear wall 105f of the radome 105 or is formed with a smaller thickness, so that the rear wall 105f of the radome 105 between the rear side 22c of the side web 22 'a of the anchoring portion 21 and the shoulder portion 43 "(which surrounds the rest portion 43 'of the antenna feet 43) is firmly pressed and thereby held.
- the described U-shaped anchoring portion 21 has, as described, two metal side webs 22a, 22 'a, wherein each of these two metal side webs 22a, 22' a can serve as a mounting plane ME or as a sectional plane SE, at the end of the active components directly or anchored indirectly.
- the cutting plane SE, along which the first component space 29 merges into the second component space 41 or is subdivided into these two component spaces 29, 41, will ultimately run in this area.
- a corresponding cross-sectional view similar to Figure 2b is shown in Figure 6, wherein in Figure 6 in deviation to Figure 2b nor the additional second and / or active components 141 in the second and / or active component space 41, so the so-called second or active component level 41 'housed and mounted.
- the desired optimum shielding is also achieved for these active components 141.
- the projection that is to say the height dimension M with which the second shielding wall 27 projects beyond the mounting plane ME (which thus also forms a sectional plane SE) in the rearward direction H, can be designed and adapted such that the desired shielding effect is sufficient Dimensions for the second or active components 141 occurs.
- this measure M may have a value that is at least 5%, preferably at least 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45% or at least 50% of the height or depth T the second or active component 141 corresponds ( Figure 6). Therefore, this dimension M, with which the shielding wall projects beyond the mounting plane ME in the rearward direction H, can be at least 5 mm, preferably at least 7.5 mm, 10 mm, 12.5 mm, 15 mm, 17, 5 mm or at least 20 mm and more. In contrast to the illustration according to FIG. 2b, a single-column antenna is reproduced on the basis of FIG.
- the single-column antenna is the actual reflector 10, on which the radiator or radiator groups 13 are mounted, via the side bars 10a directly into a connecting web 18 on both sides, then on another bend connecting the first shielding wall 19, the corresponding anchoring portion 21 and the second shielding wall 27.
- Figure 8 is shown only in deviation that in the context of the invention, other modifications with respect to the formation of the overall reflector 16 are possible.
- the first Schirmungswand 19 can pass directly into the second Schirmungswand 27, so over the so-called mounting plane ME away, then to one or, for example, two corresponding bends 51, 53 (ie two 90 ° bends 51 or a continuous 180 ° bend 52) to be returned to the level of the mounting plane ME again.
- the anchoring section 21 formed in this way in the manner of an U-shaped mounting web 22 open in this exemplary embodiment, then merges into a subsequent mounting flange 22d, which lies at the level of the mounting plane ME and extends in this plane.
- the outwardly facing web wall 22a of the U-shaped anchoring section 21, ie the U-shaped mounting section 22, is part of the second shielding wall 27.
- the two parallel webs 22a of the cross section U - Shaped anchoring portion have such a narrow arc section 52 on ⁇ , that these two sections over the entire surface lie on each other, so do not have to form a gap in between.
- PIM passive intermodulation
- a variant is preferred at this point, in which a minimum distance between the above-mentioned two parts is present, for example, by interposing a dielectric or other Spacer is ensured.
- the radome 105 may overlap the overall reflector 16 thus formed, in which case the slot-shaped or groove-shaped pocket 109 in the radome 105 engages the two web walls 22a comprising an anchoring or mounting section 21, 22.
- the connector strip 133 would also be mounted on the outgoing mounting flange 22d or an angle projection 22e protruding therefrom.
- the illustrated overall reflector 16 may, in a preferred embodiment, consist of a stamped and folded, i. bent metal part, i. in particular a sheet metal or metal plate and be made. In this case, the reflector may also be provided with a hole pattern to reduce the weight.
- a trained total reflector 16 can accommodate the necessary weights including wind forces with appropriate dimensioning. This is preferably realized as explained by the fact that the radome 105 and the total reflector 16 are matched and adapted to one another in terms of their dimensions, so that much better loads can be absorbed and supported by the mutual support in the installed state and the reinforcement caused thereby than would be expected from the sum of the individual components per se.
- the overall reflector 16 can also be formed from a continuous casting or extruded part, for example from a strand metal press, for example using aluminum. From the described exemplary embodiments, it is apparent that the radome is completely closed in the circumferential direction in wide areas of its longitudinal extension. The design may be preferred such that the radome 105 is closed to more than 20%, in particular to more than 30%, 40%, 50%, 60%, 70%, 80% or more than 90% of its total length in the circumferential direction ,
- the mentioned mounting plane ME and / or the so-called sectional plane SE may be different from the representations in the drawings with respect to the anchoring sections 21, namely be positioned closer to the actual reflector plane C or further away therefrom.
- this assembly and / or cutting plane ME or SE does not necessarily have to be designed to extend only in a contour line.
- the plane may eventually have gradations or be at an angle. These levels represent only an imaginary separation plane between the first component space 29 and the second component space 41. In other words, regardless of the actual attachment of the active components, they may, for example, project at least partially into the so-called first component space 21. Conversely, parts which are accommodated in the first component space 29 can project beyond the so-called assembly or cutting plane into the second component space 41.
