Abstract
Novel microwave phase shifters are proposed and fabricated utilizing nonreciprocal wave propagation whose insertion loss is independent of the obtained angle in phase shift. The fabricated phase shifter consisted of a ferrite ring resonator whose feeder point can be mechanically adjusted to give 360° phase-shift angle at relatively constant insertion loss. Measurements are compared with calculations.
