Ferrite phase shifter on frequency 94 GHz

摘要

Results of the design and experimental research of the waveguide ferrite phase shifter with magnetic memory for the 3-millimeterwave phased antenna array with electrical beam scanning are discussed. The phase shifter is based on an open longitudinally magnetized ferrite rod and operates at the waves of circular polarization of electromagnetic fields. The system of longitudinal magnetization is arranged inside the waveguide and includes a magnetizing coil and a system of ferrite conductors. Such construction of the phase shifter provides a fast response time, small energy consumption for operational cycle, and high activity and Q-factor.
