Abstract
Each of a transmitter and a receiver connected to an antenna through a duplexer includes a .pi./2 and a .pi. polarizer and an ortho-mode transducer (OMT) serially interconnected. In the receiver the OMT is connected at one output to a branching circuit and at the other output to a coupler which is connected to the branching circuit through a transfer circuit. In the transmitter, the OMT is connected at one input to a branching circuit and at the other input to a coupler subsequently connected to the branching circuit through a transfer circuit.
