초록

본 논문에서는 SIR(Stepped Impedance Resonator) 구조를 이용한 초광대역(UWB:Ultra Wide Band) 개방형 스터브 대역통과 여파기를 제안한다. 제안한 개방형 스터브 대역통과 여파기는 초광대역을 구현하기 위해 스터브 위치에 SIR 구조를 적용하였으며 낮은 삽입손실을 갖는다. 제안된 대역통과 여파기의 대역폭은 중심 주파수 5.8GHz에서 103% 이고, 삽입 및 반사손실은 각각 0.17dB 및 13.1dB이며 전체의 크기는$21.6{\times}17.8mm^2$ 이다.

In this paper, an UWB (Ultra Wide Band) band-pass filter with open stubs using SIR (Stepped Impedance Resonator) structure is presented. The proposed band pass filter (BPF) has SIR structure instead of open stubs for UWB application with low insertion loss. The bandwidth of the proposed BPF is 103 % at the center frequency of 5.8GHz and the insertion and return losses are 0.17dB and 13.1dB, respectively. Also, the entire size of the proposed band-pass filter is $21.6{\times}17.8mm^2$.
