ABSTRACT:
A millimeter wavelength monolithic ferrite circulator/antenna device is pided comprising a four-sided ferrite rod having one end which is to be selectively coupled to millimeter wavelength radar transmitter and receiver apparatus and the other end coupled to a load. The rod end coupled to the radar apparatus has a pair of permanent magnets disposed on opposite sides of the rod and is shaped as a right prism having prism bases formed by sections of the rod sides on which the magnets are mounted and prism faces formed by sections of the remaining two rod sides and by the cross-section of the rod itself. The dc magnetic field produced by the magnets is perpendicular to the longitudinal axis of the rod and causes the prism to act as a ferrite circulator with respect to millimeter wave energy transmitted through the prism faces and along such rod axis. The remainder of the rod is utilized as a ferrite rod antenna of the leaky-wave type by providing energy emitting perturbations on one of the rod sides.
