Abstract

In this paper, a compact partial H-plane filter with periodic structure is proposed. Guided wavelength of periodic structure' is reduced by slow wave effect. Cross-section and length of partial H-plane filter with periodic structure are considerably reduced by 75% and 30%, respectively, as compared with conventional E-plane filter. In addition, spurious responses of the bandpass filter are improved. To design bandpass filter with periodic structure, we have analyzed a periodic structure of partial H-plane waveguide and derived equations of the periodic filter. Measured results are in good agreement with simulated results.

본 논문에서는 주기 구조를 이용한 소형화된 partial H-plane필터를 제안하였다. 주기 구조의 관내 파장은 저속파의 영향으로 인해 그 크기가 줄어든다. 주기 구조를 이용한 partial H-plane 필터는 일반적인 E-plane 필터보다 단면적과 길이가 각각 75%, 30% 축소되었다. 또한 대역 통과 필터의 스퓨리어스 응답 특성이 향상되었다. 주기 구조를 이용한 대역 통과 필터를 설계하기 위해 partial H-plane 도파로의 주기 구조가 해석되었고, 설계식이 유도되었다. 측정된 결과는 시뮬레이션 결과와 잘 일치함을 확인할 수 있었다.
