A Microwave Narrowband Bandpass Filter Using Inductive Post in Rectangular Waveguide

인덕티브 포스트를 이용한 도파관형 마이크로파 협대역 대역 통과 필터

Narrowband bandpass waveguide filters using inducive post obstacles are designed and constructed to have an equal-ripple bandwidth of 50MHz at a center frequency of 9GHz. Both the triple-post and the single-post configurations are realized and compared. The measured results for both filters show good agreement with the theoretical calculations. When the two filters are compared, the performance of the triple-post filter is better than that of the single-post filter.
