Definitions

  • the invention is based on an antenna as specified in the preamble of claim 1.
  • Such an antenna is known from US-A-3,689,929.
  • Antennas realized in stripline technology are inexpensive to manufacture and reproducible.
  • the known antennas in stripline technology and with dipoles are not to be used as omnidirectional radiators, since the parasitic currents generated on the feed device for the dipoles deform the circular diagram generated by the dipoles.
  • Known omnidirectional antennas are generally realized in coaxial technology. If several dipoles are arranged one above the other in the vertical direction, then a central feed for the individual dipoles is provided. A relatively large outlay is necessary for the production.
  • the object of the invention is to provide an omnidirectional antenna realized in stripline technology.
  • the new antenna has good circular characteristics ( ⁇ 1dB) and is broadband ( ⁇ 5% at 1 GHz). According to a development in which several dipoles are arranged one above the other, good bundling is achieved in the vertical direction. According to another development, the feed device is designed in such a way that it requires only little space on the substrate on which the dipoles are applied. As a result, the entire antenna can be made so narrow that it can be accommodated in a thin tubular radome for protection against the weather.
  • An antenna is selected for the exemplary embodiment in which a plurality of vertically polarized dipoles are arranged one above the other in the vertical direction. With such an antenna, with a suitable choice of the complex current occupancy in the vertical direction, a radiation diagram bundled in the desired manner is obtained.
  • a dielectric substrate 1 made of PTFE (PTFE: polytetrafluoroethylene)
  • copper tracks are applied in a known manner (e.g. photoetching technique). These copper tracks form the dipoles 2, 3 to 2 ( n ), 3 (n) of the antenna, the feed device 4, 4 ', 7, 7', 9 and 12 for the dipoles and a parasitic compensating radiator 11.
  • the feed device is symmetrical Bandline technology carried out on both sides of the substrate.
  • the copper tracks are not drawn to scale in the drawing.
  • a dipole In a manner known per se, a dipole consists of two dipole halves 2, 3, one half 2 of which is arranged on the top side and the other half 3 on the bottom side of the substrate.
  • the dipoles are suitably shaped in a manner known per se.
  • the conductor tracks for the feed device feed the RF power to the dipoles at the dipole centers.
  • the radiation pattern of the dipoles which is circular in the azimuth plane, is deformed by the parasitic currents on the conductor tracks of the feed device in such a way that it is no longer circular. This disturbing influence is largely compensated for in the new antenna in an advantageous manner by providing a parasitic compensating radiator 11.
  • This compensation radiator 11 is also realized as a conductor track on the substrate. It is possible to provide a conductor track extending in the vertical direction on only one side of the substrate 1 or on both sides of the substrate. The conductor track can still be replaced by several conductor track sections. However, it is important that the dipoles - viewed in the horizontal direction - are arranged between the conductor tracks of the feed device and the parasitic compensating radiator. In the exemplary embodiment, the length of the parasitic compensating radiator is equal to the maximum extension of the conductor tracks of the feed device in the vertical direction.
  • the new feeder is a combination of the "parallel feed” solution and the "serial feed with the same cable lengths” solution. It has surprisingly been found that the space required is greatly reduced as a result.
  • the RF energy is passed on via line 12.
  • the line 12 has three serial branches a, b and c.
  • the branches and the widths of the conductor tracks before and after the branches are chosen in such a way that the proportion of HF energy that is necessary to obtain the desired current distribution is passed on to the dipoles (or groups of dipoles).
  • the geometric lengths of the individual conductor tracks are dimensioned such that the electrical path lengths from the RF source to all dipoles are the same or, if an increase in the radiation pattern is desired in the vertical direction, have a specific relationship to one another.
