Millimeter-wave ferrite phase shifter in substrate integrated waveguide (SIW)

The analytical model of the ferrite phase shifter in SIW and formulae are firstly introduced. On the basis of theoretical simulation, the optimum parameters of the phase shifter have been given. Furthermore, the design of transition from ferrite phase shifter in substrate-integrated waveguide (SIW) has been investigated, and the simulation results have shown the good performance of this integrated structure.
