Definitions

  • the present invention relates to a dual-polarized horn with a first and a second polarization, which are fed separately from one another via a first waveguide and a second waveguide.
  • the present invention relates to such a dual-polarized horn antenna for use as a mobile radio antenna, in particular for a mobile radio base station.
  • Horn radiators are also referred to as waveguide radiators and usually have a horn, ie a hollow body which is open on one side and is fed by a hollow line. Radiators based on waveguide technology usually have large dimensions and are therefore not suitable for a compact design. Therefore, horn radiators have hitherto been considered unsuitable for 3D beam steering and 3D beamforming applications, since a radiator spacing of less than 1 ⁇ , preferably less than 0.7 ⁇ , and in particular less than 0.5 ⁇ , is advantageous in the vertical and horizontal directions. Smaller individual emitter spacings improve the far-field group diagram in particular, since no secondary main lobes occur in the far-field group diagram with an individual emitter spacing of less than 0.5 ⁇ .
  • Dual polarizing horn radiators pose a particular challenge in terms of compactness and electrical performance, since one radiator is used for two polarizations, which are usually different.
  • compact dual-polarized horn antennas are fed through two separate orthogonal waveguides, or through a dual-polarized waveguide.
  • WO 2015134772 A1 shows a waveguide structure for a dual polarized antenna array with septum polarizers that combine first waveguides associated with a first polarization and second waveguides associated with a second polarization and convert the like-polarization fields transmitted through the first and second waveguides into oppositely circularly polarized ones Convert fields and feed hollow radiators.
  • two adjacent septum polarizers are each fed via a common waveguide, which has a cross section which, in projection onto the aperture plane, partially extends both in the area of the aperture of the one septum polarizer and in the area of the aperture of the horn radiator assigned to one septum polarizer.

  • the second waveguide has no twisting in the transformation section 4, so that its polarization does not rotate.
  • This arrangement has the advantage that the space available in the area of the feed section 3, which is connected to a matching network and/or a distribution network, can be optimally used.
  • the first and second waveguides can be aligned identically in this area and/or have an identical cross section, and thus optimally utilize the available space.
  • the waveguides are thus only aligned orthogonally to one another in the region of the mouth section 5 and therefore only require corresponding space there.
  • the area of the waveguide cross-section in the transformation section decreases in the direction of the horn radiator. This is preferably the case both for the first and for the second waveguide.
  • the area of the waveguide cross section in the direction of the antenna is therefore smaller than the area of the waveguide cross section in the direction of the distribution network.
  • the waveguides therefore have a higher wave impedance and a higher lower limit frequency (cut-off frequency) in the direction of the antenna than in the direction of the distribution network.
  • the transformation section with the waveguide cross-section change for field and impedance transformation has the advantage that orthogonally polarized radiator openings can be nested compactly on the antenna side, while a larger, broader bandwidth and lower-loss standard waveguide can be used on the side of the matching and/or distribution network.
