Definitions

  • the invention relates to a dual polarized. dipole antenna according to the preamble of claim 1.
  • the antenna becomes a polarization alignment of ⁇ 45 ° is used.
  • a common antenna housing in front of a reflector are usually in the vertical direction several such dipole squares for transmission in one frequency range and for example between two such vertically arranged one above the other Dipole squares another dipole square for transmission arranged in the other frequency range.
  • the predominant horizontal half-width the antenna is 65 °.
  • the orientation of the dipoles is + 45 ° or -45 °. Resulting from this arises a so-called dipole square.
  • the two horizontal radiation diagrams of + 45 ° and -45 ° polarizations should be as congruent as possible be aligned. A deviation is called a tracking error designated.
  • the object of the present invention is therefore that To overcome disadvantages according to the prior art and to create an improved dual polarized antenna.
  • Another advantage is that the whole Cable expenditure compared to conventional antenna devices can be reduced.
  • the surprising solution according to the invention lies in this justifies that the two opposite parallel dipoles of a dipole square, with the same Radiate or receive polarization, not in parallel or with balanced cables or with separate ones Cables are fed in, but that the feed done only with respect to a dipole and from the feed point then a coaxial one at one dipole Connection cable for Infeed on the opposite second, parallel Dipole is provided.
  • This connecting line shows an electrically effective length such that each parallel dipoles of a corresponding dipole square are excited in phase.

  • the tracking behavior according to the requirements can be preset differently. This can be done in one preferred embodiment of the invention that, for example, the feed from the feed cable coming only on the same side with the corresponding polarization-oriented dipoles and for all dipoles in the same way starting from there Connection cable to the opposite dipole to lead.
  • a change in tracking behavior or size the synchronization of the radiation diagrams or a deviation of the two radiation diagrams for the two polarizations can also be realized in that for example of four dipole squares arranged one above the other the feed in terms of parallel to each other arranged dipoles with three dipole squares each related to the dipole on the left and only with respect of a dipole square only with respect to the parallel one Dipoles on the right.
  • the antenna can be different if necessary selectable series feed to compensate for the Frequency dependence of the radiation diagrams and for compensation of tracking error, which is completely surprising and is not obvious.
  • the solution according to the invention also offers the further one Advantage that only one with a correspondingly large size Cross section of two feed cables dipoles offset by 90 ° is provided, and that only one of these two dipoles with a thinner one Cross section equipped connecting cable to the each opposite dipole of a dipole square must become. This will reduce the total cable effort significantly reduced.
