Definitions

  • the invention relates to a dual-polarized cross dipole and an antenna arrangement with two such dual-polarized cross dipoles.
  • Dipole radiators for example, are from the previous publications DE 197 22 742 A as well as DE 196 27 015 A known. Such dipole radiators can have a usual dipole structure or, for example, consist of a cross dipole or a dipole square, etc.
  • Such dipole radiators are usually fed in such a way that one dipole or radiator half is connected to an outer conductor in a direct current (i.e. galvanic) or capacitive or inductive (i.e. electromagnetic) manner, whereas the inner conductor of a coaxial connecting cable is connected to the second dipole or radiator half in a direct current (i.e. again galvanic) manner ) or is connected capacitively or inductively.
  • the feed takes place at the end regions of the dipole or radiator halves that face each other.
  • This includes four spaced-apart, non-overlapping dipole wings, which are arranged at a distance from a reflector by a carrier.
  • the supply takes place via appropriate feed lines or circuit boards that are galvanically or capacitively coupled to the respective wings. These feed lines of the different dipole radiators cross each other.
  • the individual dipole wings are arranged at a distance from one another without overlapping. They are also arranged at a distance from the reflector via appropriate supports. Feed lines such as cables or microstrips are led up from the reflector in the direction of the respective dipole wing along the carrier and cross each other in the upper end area before they are galvanically soldered to the respective dipole wing.
