Embodiment Construction

[0012] figure 1 A block diagram of a splitter according to the invention is shown. The splitter includes a common port (or common input / output) connected to a waveguide antenna part, such as a corner, and includes two separate ports (or separate input / outputs), connected on the one hand to a transmit circuit and on the other One side is connected to a receiving circuit. figure 1 Arrows indicated in are intended only to indicate the direction of wave travel in a given transmit or receive configuration. Assuming the transmit and receive circuits (and frequency bands) are reversed, the direction of the arrows can also be reversed without any other modification of the splitter. A polarization splitter 1 connected to a common port splits the wave from the antenna into two sets of waves with two different polarizations, in this example two linear and mutually perpendicular polarizations. The first transition zone 2 is connected to the polarization splitter 1 to transmit (or rec...

Abstract

The invention proposes an optimized solution of a frequency / polarization splifter that requires no adjustment after production and can be produced entirely by moulding. The polarized-wave splitter comprises various components, including a polarization splitter 1 coupled to two filters 3 and 5 via transition regions 2 and 4 . The overall dimensions of the various components are such that the transfer characteristics of the splitter are better than the characteristics resulting from the sum of the characteristics of the components constituting the splitter.

Description

technical field [0001] The present invention relates to a waveguide band / polarization splitter. In particular, the present invention relates to a linear polarization splitter which includes waveguide filtering to separate transmitted and received waves. Background technique [0002] Two-way satellite transmissions use different transmit and receive frequency bands. It is known to use different transmit and receive polarizations. Furthermore, in order to meet high frequency and polarization separation constraints when allocating frequency bands, it is known to use waveguide technology. To date, devices of this type have not been mass-produced and the individual components are relatively expensive to produce. [0003] Currently, there are no compact high-performance splitters that can be mass-produced at low cost. Contents of the invention [0004] The present invention proposes an optimized solution for polarization / frequency splitters that requires no adjustments after...
