Abstract :
The results of the design and experimental investigation of a waveguide ferrite phase shifter with magnetic memory for 3 mm-wave phased antenna arrays are discussed. The phase shifter is based on a longitudinally magnetized ferrite rod and operates with circularly polarized waves. The system of magnetization includes a coil and a system of ferrite conductors. This construction of the phase shifter provides a fast response time, small energy consumption for the operational cycle, and high activity and Q-factor.
