PASSIVE ELECTROMAGNETIC WAVE DUPLEXER COMPRISING A SEMICONDUCTOR

摘要

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