Abstract

In this paper, we propose a substrate integrated waveguide(SIW) power divider to yield excellent broadband isolation performance. In order to achieve high broadband isolation, a two stage Wilkinson power divider is employed in SIW. The measurement results show the insertion loss($S_{21}$, $S_{31}$ to be $4.0{\pm}0.5$ dB) and input return loss($S_{11}$ of 10 dB) from 13.12 GHz to 16.14 GHz. Moreover, the results show that the output return loss and isolation between output ports are larger than 10 dB between 10.37 GHz and 17.64 GHz.

본 논문에서는 광대역 격리 특성을 갖는 개선된 기판 집적 도파관(substrate integrated waveguide) 전력 분배기를 제안한다. 제안된 전력 분배기는 2단 월킨슨 전력 분배기의 구조를 기판 집적 도파관에 적용함으로써 우수한 입출력 정합 특성과 광대역 격리 특성을 갖는다. 측정 결과, $13.12{\sim}16.14$ GHz의 주파수 대역에서 삽입 손실은 $4{\pm}0.5$ dB, 입력 반사 손실은 10 dB 이상으로 나타났다. 또한, $10.37{\sim}17.64$ GHz의 주파수 대역에서 출력 반사 손실과 격리 특성은 10 dB 이상을 나타냈다.
