These can radiate and receive, for example, in one or two mutually perpendicular polarizations.
  • the radiator elements can be designed to receive only in a frequency band.
  • the antenna arrangement can also be designed as a multi-band antenna, for example for transmitting and / or receiving in two mutually offset frequency bands. Also so-called triband antennas and other frequency bands comprehensive multi-range antennas are known.

Thus, certain recesses may be provided in the webs, for example recesses in the region of the axis or of the bending region, in particular if the axis or the bending region have a certain distance from the reflector.
  • the electrical connection between stationary and moving parts then has the corresponding slots or gaps.
  • This slot leads in particular when the dipole radiators are not aligned vertically but horizontally or horizontally in front of the reflector, so for example in dual polarized radiators, which are aligned at a + 45 ° or -45 ° to the vertical or horizontal are, to a partially undesirable change in the radiation pattern.

Above all, a high isolation between the terminals of the different polarizations of, for example, 25 dB, 30 dB, etc. can be realized. Another major advantage is the high intermodulation strength for multi-carrier or wideband systems.
  • the corresponding antenna arrangement is constructed such that at least one column is provided with a plurality of radiators arranged side by side or one above the other in the longitudinal direction.
