Abstract

This paper presents the design and implementation of the CPW end-coupled band-pass filter with the finitely backed conductor (FBC). To reduce the large insertion loss in CPW structure, the improvement in loss characteristic through the change of CPW structure is introduced. The CPW filters with narrow bandwidth are suggested and characterized for their microwave performance using the finitely backed conductor. This structure

본 논문에서는 Finitely Backed Conductor(FBC) CPW(Coplanar Waveguides) 구조를 이용한 대역 통과 필터를 제안한다. 특히, 마이크로 스트립 전송 선로와 비교하여 CPW구조의 단점인 적은 결합량 문제를 해결하기 위한 방법으로 구조적 변화를 통한 특성 향상을 소개한다. 본 논문에서는 FBC 구조를 이용하여 협대역 대역 통과 필터를 제안하였으며, 측정 결과를 통해 삽입 손실의 향상 효과를 확인할 수 있다. Finitely backed conductor(FBC)를 이용한 CPW 대역 통과 필터를 설계하기 위해 FEM 방식을 이용한 HP사의 HFSS 소프트웨어를 사용하였다.
