ABSTRACT:
A waveguide apparatus guides a first pair of horizontally polarized transmit and receive frequency signals independently of and in parallel with a second pair of vertically polarized transmit and receive frequency signals. The waveguide apparatus is constructed to operate across the 3.7 to 6.425 GigaHertz band with a very narrow bandwidth for the transmit frequency and a very narrow bandwidth for the receive frequency and with a single size of rectangular waveguide for separating the transmit and receive frequencies. This construction simplifies frequency separation filtering techniques and provides effective operation over this broad band with an apparatus which is efficient in terms of space, compact and implemented by a simple package.
