Abstract
An electromagnetic radiation converter for receiving and converting microwave signals having a circular or linear polarization. The converter comprises a waveguide for transmitting both circularly and linearly polarized signals, and a first mode transducer for converting the vertical component of the microwave signal into a corresponding signal on a microstrip line, a second mode transducer for converting the horizontal component of the microwave signal into a corresponding signal on a microstrip line, and means for combining the outputs of the first and second transducers. When receiving a circularly polarized signal, the combination means adjusts the phase of the vertical and horizontal components of a circularly polarized signal such that the phase of the vertical and horizontal components are equal prior to being combined so as to produce a signal equivalent to the circularly polarized signal originally received.
