Abstract:
A co-polarized diplexer for coupling a receiver and a transmitter to a single antenna so as to allow for the simultaneous transmission and reception of co-polarized signals, the co-polarized diplexer comprising:a waveguiding structure defining a junction for separating a first signal having a first frequency and a second signal having a second frequency in the waveguiding structure, the first and second signals being co-polarized, the first frequency being different from the second frequency;a first filter, operatively connected to the waveguiding structure, for filtering the first signal; anda second filter, operatively connected to the waveguiding structure, for filtering the second signal;wherein all internal surfaces of the co-polarized diplexer are visible from external to the co-polarized diplexer and the co-polarized diplexer is of an integral cast construction.
