Definitions

  • the invention relates to a dipole radiator arrangement according to the preamble of claim 1.
  • Dipole radiators are for example from the Vorveröttingungen DE 197 22 742 A such as DE 196 27 015 A known.
  • Such dipole radiators can have a conventional dipole structure or consist, for example, of a crossed dipole or a dipole square, etc.
  • a so-called vector dipole is eg from the pre-publication WO 00/39894 A1 known. Its structure seems to be comparable to a dipole square. However, due to the specific design of the dipole radiator according to this prior publication and the special feed of this dipole radiator acts much like a Wiendipol, which radiates in two mutually perpendicular polarization planes. In constructive In particular, it is rather square because of its outer contour design.
  • Such dipole radiators are usually fed in such a way that a dipole or radiator half is DC-connected (ie galvanically) to an outer conductor, whereas the inner conductor of a coaxial connecting cable is connected to the second dipole or radiator half in a DC manner (ie in turn galvanically).
  • the feed takes place in each case at the mutually facing end portions of the dipole or radiator halves.
  • the CN 103 380 542 B shows a dipole radiator arrangement which transmits and receives in two mutually perpendicular polarization planes. Furthermore, a passive beam shaping frame is shown, which is arranged in the reflector parallel to the radiator halves in the direction of reflector. This beam-forming frame has at its corner areas widenings, which are directed inwards.
  • the WO 2014/205733 A1 shows a cross dipole, the radiators of which are surrounded by a plurality of spaced-apart beam forming frame segments. These beam forming frame segments always have the same thickness and are bent inward towards the radiators at the areas where they meet.
  • a dipole radiator arrangement which transmits and receives in two mutually perpendicular polarization planes. Between the necessary radiators and the reflector beam forming frame is still arranged. This always includes the same thickness and runs only parallel to the radiator plane. Above the spotlights is still a director arranged.
  • the EP 2 595 243 A1 shows a dipole radiator arrangement, wherein the radiators have segments facing in the direction of the reflector. Distanced from the spotlights is still a director arranged.

  • a passive beam shaping frame is shown, which is arranged in the reflector parallel to the radiator halves in the direction of reflector.
  • a director is shown, which is arranged parallel to the radiator halves, wherein the radiator halves are arranged closer to the reflector than the director.
  • radiator arrangements of the prior art have too low a bandwidth.
  • the dipole radiator arrangement comprises two pairs of radiator halves, which are arranged rotated by 90 ° to each other, so that the dipole radiator arrangement in two mutually perpendicular polarization planes sends and / or receives.
  • Two radiator halves, which form a pair, are arranged diagonally to each other.
  • the radiator halves can be arranged or arranged parallel to this in a radiator plane at a distance in front of a reflector.

  • the bandwidth can be markedly increased.
  • the reflection factor of the dipole radiator arrangement improves in the lower frequency range.
  • Such a dipole radiator arrangement can therefore be used in particular in the frequency range from about 550 MHz to about 960 MHz.
  • the dipole radiator arrangement according to the invention can also be used.
  • the widenings of the frame web extend on its inner peripheral wall, so that the frame web in the area its corners extends closer in the direction of a longitudinal axis through the dipole radiator array. It is also possible that, alternatively or additionally, the widenings of the frame web extend on its outer circumferential wall.
  • radiator halves overlap at least partially or completely with the widenings of the frame web which are formed on its inner circumferential wall.
  • the broadening is preferably carried out tapered, so in one or more stages intermittent. It would also be possible for the broadening to occur continuously.
  • the outer peripheral wall of the frame web is chamfered in the region of its corners, wherein the broadening is formed transversely to the radiator plane at this bevel.

  • the tabs further preferably extend toward the center of the passive beam forming frame and in this case are formed on an inner circumferential wall of the frame land. It would also be possible for the flags to extend in the opposite direction, ie outwards. In this case, they would be arranged on an outer circumferential wall of the frame web.
  • the bandwidth can also be increased by using a director instead of the metal strips, the director being oriented parallel to the radiator plane.
