Definitions
- Dual polarized antenna arrays i.e. radiator arrangements, which dipoles, slots or planar radiator elements for simultaneous reception or simultaneous emission electromagnetic waves with two orthogonal linear Polarizations that are separate and separate from each other decoupled outputs are sufficient known.
- radiator arrangements can, for example of several elements in the form of dipoles, Slits or planar emitter elements exist as they do for example from EP 0 685 900 A1 or from the prior publication "Antennas", second part, by Adolf Heilmann, Bibliographical Institute Mannheim / Vienna / Zurich, 1970 University pocket book publisher, pages 47 to 50, known are.
- This applies to omnidirectional spotlights for example with horizontal polarization the shapes of a dipole square or a dipole cross known, which is a coupling between the two systems offset by 90 ° exhibit.
- radiator modules To increase the antenna gain, it is possible to use several these radiator modules to antenna fields, so-called arrays, interconnect. It is per sending and receiving station not uncommon, ten or more radiator modules interconnect to an array.
- the spotlight modules can be arranged side by side or one below the other.
- the direction in which the emitter modules are straight or inclined should be arranged next to or below each other be referred to as the alignment of the antenna array.
- the object of the present invention is therefore a To create X-polarized antenna array, which is preferred broadband a high decoupling between the resulting Has feed systems for both polarizations.
- Decoupling device with a new type of decoupling structure is provided.
- This decoupling structure is completely different to the z.
- the invention Decoupling structure has a longitudinal extension on, in the vertical mounting direction two side by side Arrays arranged (basically also with horizontal Direction of attachment of two arrays arranged side by side) is aligned. In other words, they are already good Results with a vertically aligned X-polarized Array e.g. then achieved when between two on top of each other arranged radiator modules in the vertical direction extending longitudinal rod is provided.
- a longitudinal slot or another decoupling structure with an elongated recess or extension introduced is.
- the conductive ones cross-shaped structural elements of the decoupling structure connected at their intersection.
- the first is the embodiment received according to Figures 1a and 1b.
- a dipole square for example a square structure have
- the radiator modules 1 are in front of a reflector 7 Dipoles at a distance from the reflector 7 sitting on it assembled.
- the reflector 7 by a metallization 9 on a circuit board 11 formed on the back of a feed network 13th is located, which separates the individual radiator modules interconnects for the respective polarization.
- the dipoles 3 are compared via a so-called symmetrization 14 the circuit board 11 held mechanically and electrically contacted, d. H. so fed from the board 13.
- the longitudinal or extension component of the decoupling structure 17, which in the following also partially as a decoupling structural element 17 is according to the Embodiment according to Figure 1a or 1b larger than at least 1/4 of the distance between the two neighboring ones Centers or base points 23 of the radiator modules or corresponds 1/4 of this distance.
- the longitudinal component is preferably more than 40 or 50% of the said Spotlight module distance 25.
- the rod 17a shown is a short distance above the Reflector surface 7 is arranged and is a spacer 18 on the reflector 7, i.e. mechanically held by the circuit board 11 and with the reflector 7 electrically contacted.
- the decoupling structure could but also further than the double dipole arrangement 3 be removed from the reflector surface 7, wherein however then influences on the radiation diagram at good decoupling can be determined if the distance of the decoupling structure 17 from the reflector surface is more than half as far away as the dipoles the double dipole arrangement 3.
- the arrangement is preferred such that the conductive decoupling structure 17 in shape of the rod 17a not more than 1/8 to 1/4 wavelength is removed from the reflector plane.
- the arrangement can be such that the dipoles 3 'for example at a distance of 0.1 to 0.5 Wavelengths, preferably 0.2 to 0.3 wavelengths, in particular by 0.25 wavelengths, in front of the reflector surface sit, the decoupling structure in the form of the decoupling structure element 17a a distance of 0.015 up to 0.125 wavelengths, in particular 0.015 to 0.035 wavelengths (i.e. about 1/60 to 1/8, especially 1/60 to 1/30 of the wavelength), opposite the reflector surface 7 can have.
- the decoupling structure 17 is not in the form of a Rod, but in the form of a plan view of Figure 1a congruent to the rod shown there in the reflector surface 7 slot introduced.
- a conductive surface at a distance in front of the reflector surface in which a corresponding one Recess is introduced, which has a structure with a longitudinal extension, preferably parallel and in the area of the connection or mounting direction 21 lying.
- the exemplary embodiment according to FIGS. 2a, 2b and 2c differs from the exemplary embodiment explained above in that for the decoupling structure 17 no rod extending in the connecting direction 21 17a, but a cross-shaped decoupling structural element 17b is used from two crossing bars.
- a schematic perspective illustration is shown in FIG. 2c of the embodiment shown in Figures 2a and 2b.
- the rods 27 are in this embodiment almost perpendicular to each other, the two rods almost parallel to the polarization planes, i.e. to the dipoles 3 'are aligned.
- the cruciform Decoupling structural element 17b with the rods 27 also conductive again, the two rods 27 in their intersection 29 are conductively connected.
- the longitudinal component in the connection or mounting direction 21 of the cross-shaped decoupling structure 17 thus formed 0.25 to 1 wavelength, for example, preferably 0.5 to 0.8 wavelengths, especially around 0.7 Wavelengths.
- the projection is under "longitudinal component" on the vertical, i.e. on the direct connecting line between two neighboring radiator modules in To understand the direction of cultivation. Because of the symmetrical Structure is the extension in the transverse direction to the direction of attachment 21 of the same length, but this does not have to be mandatory.
- Patch emitters 1a such as basically from the ITG technical report pre-publication 128 "antennas" (lectures of the ITG conference from April 12 to 15, 1994 in Dresden), VDE-Verlag GmbH, Berlin, Offenbach, pages 259 to 264 are known. It deals are aperture-coupled microstrip patch antennas with a cross slot or offset slot arrangement to receive two orthogonal linear Polarizations.
- the patch radiators 1a have square shapes in plan view Structure on and are with their slot arrangement each again aligned at a 45 ° angle to the vertical V in order to both + 45 ° and -45 ° polarizations received or to be able to send.
