Millimeter-wave substrate integrated waveguide ferrite phase shifter for wireless communication application

The design idea and technique of the substrate integrated waveguide (SIW) ferrite phase shifter has been investigated. Firstly, on the basis of theoretical simulation, the optimum parameters of the phase shifter have been given. And then, the design procedure of transition from ferrite phase shifter in SIW to CPW has been introduced; and the agreement between the simulation results of the final integrated structure and the experimental results of the equivalent model has shown the good performance of this integrated structure.
