Definitions
- the invention relates to an RF connection for connecting an RF component to an antenna, in particular a mobile radio antenna of a base station.
- Communication can be carried out in a cell assigned to a mobile radio antenna between mobile subscribers via stationary mobile radio antennas.
- the mobile radio antenna is usually mounted on a mast, on a housing roof or generally on a building etc. in order to illuminate a corresponding area.
- the actual base station in which the electrical components, including amplifiers, filter systems, etc. are accommodated, is provided close to the floor or near the housing, usually at the foot of the antenna mast. Via cables from here that lead to the antenna, the electrical connection for supplying and receiving the signals transmitted or received via the mobile radio antenna is then established.
- a generic antenna is known for example from EP 0 973 231 A2. It has on its underside an electrical connection for a connection between the antenna elements and remote electrical / electronic components. To this end, the electrical connection connection must have an antenna-side connection section which interacts with a cable-side connection section for connecting the cable to the antenna.
- a coupling device for coaxial line systems has also become known from EP 0 489 252 AI.
- This coaxial line system two inner conductor sections of two coaxial lines are coupled without contact, so that an open-circuit short-circuit transformation is made possible.
- This known coupling device for a coaxial line system consists of two lines, which are arranged in two offset planes. The outer conductors are formed in a square or rectangular cross section, in which inner conductors with a rectangular cross section are mounted with the aid of dielectric supports.
- the object of the present invention is to create an improved RF connector based on the prior art mentioned at the beginning, in which a simple and inexpensive replacement of RF components should be possible.
- an antenna-related amplifier, combiner, antenna-related filter module, etc. can now be accommodated directly in or on the antenna housing, so that the separate cables according to the prior art between the electronic or electrical components of the base station and the antenna input secondly, are no longer necessary. It is therefore no longer necessary in principle to accommodate the amplifier in a separate housing separate from the antenna housing and to connect it to the antenna input using high-quality cables.
- very high-quality cable connections were required for this, above all for IMA reasons (i.e. for reasons of the intermodulation distance), which were cost-intensive on the one hand, and on the other hand, their installation was also time-consuming and space-consuming.
- an interface is now provided in the antenna housing in order, for example, to accommodate and connect an amplifier, combiner, filter module and / or other electrical or electronic components directly.
- an amplifier, combiner, filter module and / or other electrical or electronic components directly.
- electrical switchable components These electrical components or the at least one electrical component can preferably be inserted into the antenna housing like a module.
- no coaxial or other galvanic plug connection is now provided directly, but rather a contact-free HF connector, via which the electrical connection between the connected electrical component and the actual antenna components can be realized.
- both the outer conductor and the inner conductor are coupled to one another coaxially and without contact in the region of the connector.
- either only the outer conductor or only the inner conductor is non-contact and the other conductor, i.e. the inner or outer lter, are then galvanically coupled.
- Coaxial connectors are preferred because they can also be coupled in a relative rotational position.
- the at least one switchable electrical component is housed in the bet-protected antenna housing.
- the assembly can be carried out, for example, via a removable cover of the antenna pointing downward. Looks in the assembled state the arrangement looks like a normal antenna. It is not recognizable from the outside that, for example, an amplifier and / or another electrical component or assembly is connected.
- a non-contact RF connector is proposed, the RF components of which can be connected to one another much more simply and cost-effectively than in the prior art.
- problems like with a classic connection such as e.g. occur with forehead or spring contacts. Poor galvanic contacts mainly cause intermodulation problems, which can lead to the failure of reception channels, especially in mobile telephony.
- the contactless connection separates the mechanical and electrical functions. A screw connection or locking device therefore does not have to fulfill any electrical functions.
- the non-contact connector can also be adapted to existing standard connectors (e.g. 7-16 connectors).
- the contactless connector also has considerable advantages in HF measurement and testing technology, because it can e.g. can be used as an IMA (intermodulation) free quick connector.
- the contact-free HF connector is constructed on the one hand without contact and on the other hand coaxially, so that the advantages mentioned above occur cumulatively and are given.
- the coaxial electrical length for the contact-free inner conductor and / or outer conductor coupling can be ⁇ / 4- Length (lambda preferably corresponds to the wavelength of the center frequency of the frequency range to be transmitted), specifically with reference to the frequency to be transmitted, preferably the center frequency of a frequency range to be transmitted.
- the inner and / or outer conductor coupling is constructed in the manner of a ⁇ / 4 pot.
- the adaptation structure can also be implemented while avoiding a ⁇ / 4 axial length for the inner conductor and / or outer conductor coupling, in particular when a corresponding adaptation structure is additionally provided. This measure can have advantages in particular in the case of a small coupling area and / or a short coupling length.
- the antenna according to the invention with the proposed contact-free connection and connection technology can be constructed in such a way that the connectors to be coupled in each case are firmly connected to associated RF components, which can be joined directly via the connector.
- the insertable electrical component has at least one permanently connected contact-free connection section which can be coupled to a corresponding antenna-side contact-free connection section.
- At least one contact-free and thereby coaxial interface is preferably provided, the one half of which is part of the electrical component which is to be connected to the antenna, the other half of the connection then being part of the antenna or the antenna arrangement.
- the component to be connected equipped with the appropriate interface, with its preferably contact-free and coaxial connection half, has to be inserted only into the corresponding antenna-side coaxial and contact-free connection half to make the electrical connection. In this position, it is then only necessary to carry out the mechanical fixation for the connected electrical component in order to ensure a secure hold.
- the capacitive and / or electrical-galvanic contact-free connection offers great advantages with regard to assembly. Problems that occur and can occur in conventional galvanic contact technology with regard to spring and face contacts are avoided in the contactless coupling according to the present invention.
- the plug-in connection of a multi-L connector can thus be made with an assembly unit. Not all connectors have to be put together individually.
- a coupling or a contactless connection can also be implemented using standard connectors such as 7-16 or N sockets within the scope of the invention.
- the invention is particularly suitable for the transmission of high: HF powers, whereby the desired DC decoupling can also be realized due to the contactless coupling, which has advantages in particular when an electrical connection to an amplifier, a measuring device etc. is realized should.
- the RF connector according to the invention also enables a large frequency bandwidth to be implemented.
- the HF connector explained can also be axially sealed in its outer conductor coupling point (for example in a pot) by a simple O-ring (for example silicone). It would thus be possible to attach the electrical component, for example directly to the underside of the antenna, via an interface formed there, so that the connected component would not be mountable below a common antenna housing, but directly adjacent to it in a separate housing.
- a simple O-ring for example silicone

- an antenna 301 is shown in a schematic side view, which can be attached via an attachment 303 above and an attachment 305 below, for example to an antenna mast - which is not shown in FIG. 1.
- the antenna comprises a housing 307 with a base or mounting plate 309, on which, as shown in FIG. 1 (in which the antenna is shown in schematic cross section), a housing cover 311, namely a so-called radome, can be placed in order to to protect the components below the radome from the weather.
- an antenna is shown for schematic clarification only, which comprises two cross dipoles 315 which are arranged vertically offset one above the other.
- the associated dipoles 315 'and 315 "are oriented at a + 45 ° or -45 ° angle with respect to the horizontal (or vertical), as is well known.
- an electrical component 319 is now connected, which can consist, for example, of an amplifier (for example a so-called TMA amplifier), i.e. e.g. a "Top Mounted Amplifier".
- an amplifier for example a so-called TMA amplifier
- TMA amplifier i.e. e.g. a "Top Mounted Amplifier”.
- two RF connections 5 are provided in the exemplary embodiment shown, each of which, for example, has an antenna-side connector 7 (in the exemplary embodiment shown game in the form of a plug connector 7) and a second connector 9 (in the exemplary embodiment also shown in the form of a plug connector 9) which can be connected to the interface 321 thus formed, which is part of the switchable electrical component 319 in the exemplary embodiment shown and is preferably permanently connected to it is, that is, not via flexible coaxial cables connecting the connector 9 to the switchable component 319.
- connection sections 7 and 9 are also sometimes referred to below.
- the connectors 7 and 9 are preferably plug-in connectors, which can each be formed in the form of a plug and a coupler interacting therewith. It follows from the entire description
- the connector can be designed both in the form of a coupler and in the form of a plug as a free or fixed connector (plug connector).
- Fixed connectors plugs or couplers are used when they are on a wall or a bridge, for example
- FIG. 4 the end region of the antenna 301, which is generally at the bottom in the area of use and on which the one coaxial connector 7 is provided, is shown schematically. Furthermore, part of the
- the antenna 301 or the antenna elements belonging to the antenna 301 or other HF devices are used as the HF component 1 and the switchable one electrical component 319 also generally referred to below as RF component 1 '.
- One connector 7 is used, for example, for the supply or reception of signals relating to the dipoles, for example, at an angle of -45 ° with respect to the horizontal, whereas the second connector 7 is used for an electrical HF connection for supply or reception via the dipoles aligned at a + 45 ° angle is made possible, so that one connection 5 can receive or transmit in one polarization plane and the second connection 5 in the perpendicular polarization plane.
- the connector 7 on the left in FIG. 4 stands with an antenna-side RF coaxial line, i. H. the HF component 1 in electrical connection.
- the connector 9 on the right in FIG. 4 is connected to an associated RF coaxial line of the connected component 319, i. H. thus generally the further HF component designated by the reference symbol 1 '.
- the one inner conductor section 7a is designed in the form of a socket and for this purpose has an axial inner conductor recess 17, which is formed from the associated end face of the inner conductor section 7a in the manner of an axially extending blind bore. In this respect, one can also speak of a (more socket-shaped) coupler.
- the inner conductor section 9a of the second connector 9 cooperating therewith is of the type Inner conductor pin 19 designed, which engages in the functional position in the inner conductor recess 17 without contact. In this respect, one can also speak of a connector, plug connector or plug.
- Inner conductor pin 19 are configured with the same diameter or at least approximately the same diameter.
- the outer conductor section 7b is of sleeve-shaped design and has a diameter which in itself corresponds to the outer conductor section 9'b of the second connector 9.
- the second outer conductor section 9k> is provided with a pot 109, so that the outer conductor section 9b runs out sleeve-like over this pot 109, the inner diameter of the pot 109 being at least slightly larger than the outer diameter of the outer conductor section ending in the functional position in the pot 7b of the first connector 7.
- the contact free coupling realized.
- the size of the inner and outer conductor coupling surfaces, ie in particular the length of the inner and outer conductor coupling surfaces, can, however, turn out to be of different lengths due to the mechanical dimensions.
- the contact-free coupling of the inner conductor sections 7a and 9a and of the outer conductor sections 7b and 9b preferably takes place, ie in particular in the region of the pot 109 on the outer conductor section 9b by means of an electrical length of ⁇ / 4, based on the frequency to be transmitted or the frequency band to be transmitted ,
- the size ⁇ preferably corresponds approximately to the wavelength ⁇ of the center frequency of the frequency range to be transmitted.
- the length of the pots 109 can thus be set such that the open end of the electrical line acts as an open circuit and inside as a short circuit.
- the coupling points therefore act like a direct connection in the HF range, so that the inner and outer conductor transition is infinitely variable. This means that no matching structure is required for impedance matching.
- it can also be carried out with different axial length 'is an adaptation of the pots. In particular with a coupling surface that is small or a short axial coupling length, it may therefore be necessary to provide an additional matching structure in the connector.
- Non-conductive mechanical locking means 55a and 55b can also be connected or interact with both connectors 7 and 9, which are fastened to one another for example by means of a screw contact.
- a first and second mechanical locking means 55a and 55b can be mechanically connected to one another in order to position the electrical parts of the connectors 7 and 9 in a predetermined contactless position relative to one another.
- the non-conductive, mechanically interacting locking means 51 and 53 the two coaxial connectors 7 and 9 can be held without contact with one another.
- air is therefore used as the dielectric between the two connectors 7 and 9. Due to the coaxial design, both connectors 7 and 9 can be rotated relative to one another without the coupling effect being impaired or impaired. Even if both connectors 7 and 9 are not plugged together at the same insertion depth, adverse effects can be ruled out in wide areas.
- connection 5 In contrast to the exemplary embodiment shown, it is noted that generally two RF components 1 and 1 "to be coupled via the connection 5 can each be permanently and directly connected to the associated connector 7 or 9 (ie in the form of a fixed connector or plug connector). , so that the respective RF component 1 with the connector 7 and the RF component 1 'with the connector 9 form a fixed structural unit.
- flexible coaxial lines can also be used in principle.
- FIG. 5 shows a schematic representation of a contactless coupling to a standard socket 31, which in the exemplary embodiment shown has a schematically represented inner conductor section 9a and an outer conductor section 9b.
- the inner conductor section 9a can basically be designed in the form of a plug and a socket, into which or into which a coaxial connector with a corresponding plug-shaped inner conductor can usually be inserted to produce an electrical-galvanic connection.
- a contact-free plug connection can be implemented using a connector 7 in accordance with the exemplary embodiment according to FIG. 5.
- This connector 7 now has a corresponding inner conductor section 7a with a top opening in the recess 17.
- the inner conductor recess 17 has a larger radial dimension, which is dimensioned such that the inner conductor section 9a can be inserted therein without contact.
- the outer conductor section 7b has a step-shaped, i.e. on the radially outward stepped receiving section 7 ', in the area of which the outer conductor section 9b of the standard socket 31 ends.
- the configuration is preferably such that the radial dimension between the inner lateral surface of the outer conductor 9b of the standard bushing 31 and the outer lateral surface of the outer conductor section 7b in the area of the outer conductor coupling faces 107b, 109b is equal to the radial wall thickness 35 ' Outer conductor section 7'b of the connector 7 offset to the coupling area.
- an impedance matching 41, 43 is also provided in this exemplary embodiment. This impedance matching can be done on the corresponding inner conductor section 7a and / or the associated outer conductor section 7b of the connector 7.
- the inner conductor 7'a is formed over a certain axial length with a different diameter to the inner conductor sections 7a adjoining axially in front of or behind it.
- the impedance is adjusted for the respective frequency band by means of a desired impedance transformation.
- both the outer conductor 7b and the inner conductor 7a can have a smaller radial dimension. If the inner conductor section 9a of the standard socket 31 is hollow, the outer dimension of the inner conductor section 7a can be made smaller, so that this inner conductor 7a can be inserted into the hollow inner conductor section 9a of the second connector 9. There is also the possibility of a reversal in the outer conductor in such a way that the outer or diameter dimension of the outer conductor 7b of the connector 7 is dimensioned smaller than the clear inner distance of the outer conductor 9b of the connector 9 or the socket 31.
- the entire plug-in structure of the connectors 7 and 9 or a connector 7 and a further connector in the form of a standard socket 31 can be done by means of electrically non-conductive fixing or locking means 51, 53 such that the contact-free coupling of the inner and outer conductors is not used electrically non-conductive insulating materials in between can be carried out.
- electrically non-conductive fixing or locking means 51, 53 such that the contact-free coupling of the inner and outer conductors is not used electrically non-conductive insulating materials in between can be carried out.
- only air is used between the coupling surfaces, for example. Irrespective of this, it is also possible in these areas between the Coupling surfaces otherwise usual insulating materials, in particular in the form of a dielectric, are used.
- FIGS. 4 and 5 show exemplary embodiments in which the two connecting sections or connectors 7 and 9, in which the contact-free coupling of the inner and outer conductors takes place absolutely without contact, that is to say not by using a permanently inserted insulator or dielectric.
- the dielectric in FIGS. 1 and 2 consists only of air when a corresponding connector is used in an air atmosphere.
- the exemplary embodiment according to FIG. 6 shows a modification insofar as partial fixations with non-conductive material 51 or 53 have been used here for the relative fixing of the two connectors 7 and 9.
- This non-conductive material 51 and 53 is used at different locations with different shapes.
- this non-conductive material is used, for example in the form of a spacer or ring 51a, for fixing the inner conductor 9a relative to the inner conductor 7a, specifically in the region of the free end of the inner conductor 9a.
- a second insulating material 51b is essentially used as a spacer for limiting the insertion depth of the connector 7 and 9 and is arranged in the embodiment shown in FIG.
- spacers 53a and 53b are in the form of a Non-conductive dielectric 53 is provided in order to avoid galvanic contact between the outer conductor sections 7b and 9b.
- One section 53a with insulating material 53 is again provided at the front free end of one outer conductor section 9b and the other insulating material 53 at the front end of the inserted other outer conductor section 7b.
- This material 53b is also designed such that the insertion depth of the two connectors 7 and 9 is limited relative to one another.
- FIG. 7 shows that the corresponding spacer elements 51a and 51b, which are separate in FIG. 6, can also be designed as a one-piece, continuous material 51 for the relative alignment of the two inner conductors.
- only a single spacer material has been used, which connects the spacer elements 53a and 53b used individually in FIG. 3 as a one-piece part.
- the preferably coaxial contact-free coupling with, for example, two connectors arranged in parallel for a component 319 to be connected is carried out by opening a bottom cover in the antenna, for example a cover 301a in FIG. 1, in order to subsequently connect the corresponding component 1 ', 319 only to be pushed in or to pull out an already inserted and connected component and to replace it with another one after possible mechanical fastening parts have been opened.
- this lower housing cover 301 can also be firmly connected to the component 1 ', 319 to be installed, as is indicated in FIG. 3.
- component 319 that is to say generally HF component 1 '
- HF component 1 ' can in certain circumstances be replaced relatively easily in the form of an amplifier, since an HF connection between the antenna and amplifier must be unscrewed. This reduces maintenance and assembly costs. Intermodulation problems are avoided through the contact-free connection.
- the amplifier is integrated in the antenna housing, so that only the usual antenna of the housing cover 307 is visible from the outside.

- the pin-shaped inner conductor 7'a to the associated inner conductor section 7a is arranged in the exemplary embodiment shown, which is separated from the outer conductor or outer conductor section 7'b, 7b by a dielectric 75, which can consist of correspondingly suitable insulating materials , for example also plastic, etc., but can also be formed from air.
- a coaxial cable can also be plugged directly into the connector, ie the coaxial cable would form the connector 7 on the left in FIG.
- the deviation should be less than 20%, preferably less than 10%. The best value is achieved if ⁇ corresponds to the center wavelength of the frequency range to be transmitted.
- the outer conductor coupling can then take place with or without a jump in diameter, as is shown only by way of example in the various figures.
- FIGS. 4 to 7 the inner conductor 7'a belonging to the connector 7 and shown on the left or the inner conductor section 7a was shown in the form of a socket and the inner conductor section 9a in the figures, which belongs to the connecting part 9, was always shown in the form of a pin.
