ABSTRACT:
A microwave polarizer particularly in a system for coupling energy between a waveguide and a transmission line. The polarizer reduces cross polarization by means of the probes being adjusted to an input impedance of less than 50 ohms, in particular to 20 ohms, by reducing the penetration depth of the probes. The smaller penetration depth also increases the distance between the two probes, which reduces cross polarization.
