초록

본 논문에서는 기존의 방법과 비교하여 간결한 X-band 위성 통신용 셉텀 편파기의 설계방법을 제안한다. 제안된 방법은 기존의 셉텀 편파기 설계 방법들과 비교하여 설계과정에서 소요되는 시간적인 측면과 설계방법의 복잡성 측면에서 개선된 방법이다. 더욱이 도파관형 셉텀 편파기의 해석 및 설계를 위해 등가모델링 방법을 상용 EM 소프트웨어를 이용한 전파상수(${\beta}$) 및 도파관 임피던스 계산과 전송선로 이론을 적용하였다. 마지막으로 시뮬레이션과 실제측정 결과를 통해, 위성 통신용 적합성을 확인하였다.

In this paper, a simple design method of stepped septum polarizer suitable for X-band satellite communication is proposed. This method is compared to two other conventional design methods in terms of time consumption and complexity of design procedure. In addition, an equivalent circuit modeling is used to analyze and design for the polarizer based on waveguide. For the validity of satisfying the satellite communication, electrical performances have been verified through the simulation and measurement results.
