Abstract:

A compact, symmetrical, three-port S-band circulator composed of reciprocal tee junctions and nonreciprocal phase shifters is investigated theoretically, and its experimental performance results are presented. The comparison of these results demonstrates that 1 circulators can be designed and their experimental performance described from a network model and 2 there is no theoretical limitation on the minimum amount of total differential phase shift necessary for perfect circulation. Bandwidth is investigated and techniques are discussed, including the introduction of a backward wave phase shifter, for achieving larger bandwidths. The stripline, nonreciprocal, comb- filter phase shifter used in the ring circulator is described and performance results are given.
