Abstract

In this paper, a microstrip dual mode band pass filter with doubly fed line is proposed. The proposed filter consists of a corner truncated patch with right crossed slots and doubly fed lines. In general, the resonator with the right crossed slots simultaneously has size reduction and spurious response suppression. In order to improve the rejection performance in out of its higher stop band, the dual mode resonator is excited by using doubly fed line. Details of the filter characteristics are described, and both simulated and measured results of the designed filter are presented.

논문은 이중 급전을 갖는 마이크로스트립 이중 모드 대역 통과 필터를 제안한다. 제안된 필터는 이중 모드 구현을 위해 모서리 부분을 제거되고, 직교 슬롯을 포함하는 정사각형 패치와 이중 급전 구조로 구성된다. 직교 슬롯은 공진기의 소형화 및 불요신호를 억압하기 위해 사용되고, 상측 차단 대역에서의 차단 특성을 개선하기 위해 이중 급전 구조를 사용하였다. 보다 자세한 필터 설계 방법 및 특성 결과를 본문에 기술하였다.
