A Study on the Rectangular Waveguide Phase-Shifter Partially Loaded with a Rectangular Dielectric Slab

Generally, the waveguide phase-shifter has been analyzed by the modal expansion method. We can not apply this method in the case which is difficult to choose a nenerating function. In this paper, we are analyzed the rectangular waveguide phase shifter using the perturbation method. When the depth of dielectric slab is smaller then one half of the waveguide height, the experimental results are well agreed with the calculated values by this method.
