Definitions

  • the invention relates to an arrangement in waveguide technology for the transmission of directional radio signals from two or more directional radio frequency bands with double polarization with a broadband polarization filter with a common for the two or more frequency bands first connection for connection to the antenna exciter of a double-band antenna or multi-band antenna.
  • Separate antennas are generally required for the operation of directional radio systems for each radio (RF) frequency range.
  • RF radio
  • system switches a combination of polarization and frequency switches, it is possible to connect preferably two or more RF areas to an antenna, a so-called double-band antenna, and thus to utilize the mounting and mounting surfaces on the directional radio structures twice.
  • Up to about 3 GHz coaxial cables and above about 3 GHz waveguides for only one polarization are used as antenna feeds.
  • two antenna lines are required per mono-band antenna, four antenna lines per double-band antenna.
  • Waveguides are preferably used in the clear transmission range, i.e. for the transmission of the fundamental wave.
  • suitable transitions and filters to suppress undesired higher wave types so-called mode filters, have made it possible to use waveguides in the area of higher wave types in which they have particularly low attenuation.
  • the SIRAL waveguide (Siemens rectangular aluminum waveguide) has proven to be used, for example, in a special print from the magazine "Feintechnik" 82nd year 1974, issue 7, pages 355 to 360 and in the Siemens magazine 49 (1975) , Issue 3, pages 151 to 154.
  • These waveguides can also be bent over the broad side in the transmission range of higher shaft types without restricting normal routing, twisted in the longitudinal direction and built up from part lengths that are dimensionally adapted by the customer.
  • an antenna switch for a high-frequency antenna which is intended for the transmission of frequencies between 3.6 and 4.2 GHz and between 5.9 and 7.1 GHz.
  • two directional couplers with total coupling for the frequency band 3.6 - 4.2 GHz are arranged behind the connection intended for the connection to the antenna, one of which is designed for vertical polarization and the other for horizontal polarization.
  • a polarization switch follows the two directional couplers, the common connection of which is connected to the second directional coupler.
  • a waveguide provided with a stub line is connected to each polarization connection of the polarization switch and a connection of a Y branch is connected to the end of each waveguide.
  • a first band filter is connected to the second connection of the first Y branch, and a second band filter to the second connection of the second Y branch.
  • This known antenna crossover is a compact design of a polarization crossover and crossovers connected to it via waveguide sections.
  • the entire arrangement of polarization crossover and frequency crossovers, which are directly connected to one another via waveguide sections, is arranged in the vicinity of the antenna system to be fed.
  • the individual signals are supplied from the respective signal generator to the arrangement combining them via a correspondingly large number of antenna feed lines.
  • the invention has for its object to reduce the number of four antenna feed lines (waveguide) usually required for a double band antenna.
  • the antenna feed lines consist of broadband waveguides with a rectangular cross section (SIRAL waveguide of a suitable type) or oval cross section, which are operated in the clear and / or ambiguous transmission range and contain mode filters for the ambiguous transmission range.
  • SIRAL waveguide of a suitable type
  • oval cross section which are operated in the clear and / or ambiguous transmission range and contain mode filters for the ambiguous transmission range.
  • the individual components advantageously consist of NC-milled materials.
  • the figure shows an arrangement for the transmission of RF signals from two microwave systems on only one waveguide for each polarization in a block diagram.
  • the connection of the antenna exciter e.g. a circular waveguide, called a double band antenna. 2 is a broadband crossover for the two frequency bands of the microwave systems. This is connected via two waveguides 3, each for the same polarization of both frequency bands, with a crossover 4, 5 for each polarization.
  • the crossover 4 is provided for the horizontal polarization of the two frequency bands with the frequencies f1 and f2, the crossover 5 for the vertical polarization of the corresponding frequency bands.
  • the two waveguides 3 consist, for example, of two SIRAL waveguides of a suitable type or cross section, which are used both in the unambiguous and in the ambiguous transmission range, i.e. can be operated with particularly low damping.
  • SIRAL waveguides are already being used with great success as low-loss antenna cables in the transmission range of higher wave types. With the arrangement according to the invention described above, the amount of waveguide is reduced by half, which saves a significant amount of space, but at the same time also saves material as a further advantage.
