ABSTRACT:
A passive duplexer for electromagnetic waves operated within the millimetric wave range. The duplexer comprises a first horn associated with a radar transmitter and having a propagation axis (.DELTA..sub.1), a plane circular grid inclined at 45.degree. with respect to (.DELTA..sub.1), and a second horn associated with the radar receiver and having an axis (.DELTA..sub.2) at right angles to (.DELTA..sub.1). The grid is formed by a network of resonant slots equipped with at least one diode.
