Partial H-Plane Band-Pass Waveguide Filter Using Compact Resonators

M. Hajnorouzi; H. Ghorbaninejad

In this paper partial band-pass waveguide filter using compact resonators are presented which is implemented in partial H-plane waveguide. Partial H-plane band-pass filters compared with E-plane band-pass filters, in the same frequency range, have one quarter cross section size. Partial H-plane band-pass waveguide filter with compact resonators has less longitudinally length relative to the conventional partial H-plane filters. Compact resonators in partial H-plane waveguides reduce both the cross section size and the total length of filter, in the same frequency range while compared with conventional partial H-plane filters. In the design procedure, the shape of resonators is determined by fitting the characteristic (transfer function) of a desired resonator to that obtained from an equivalent circuit model. The design process is based on optimization using an electromagnetic simulation to take the effect of higher order modes (evanescent mode). The usefulness of the proposed partial H-plane band-pass filter and its performance are verified by designing and simulating two filters.
