Abstract
In a ferrite phase shifter, a temperature rise at ferrites can be suppressed to maintain the characteristics of the frites even when used at high power. Thus, the phase shifter can stably demonstrate high performance. The ferrite phase shifter includes a rectangular waveguide, substantially sheet-like ferrites disposed to face each other with respective mounting surfaces kept in tight contact with inner walls of wide surfaces of the rectangular waveguide facing each other, and a coil which is wound around the periphery of the rectangular waveguide in a position substantially corresponding to the position of the ferrites and through which a current is passed.
