초록

본 논문에서는 마이크로스트립선의 전송선로 특성을 이용하여 5선으로 선간 간격의 폭을 조정한 값으로 시뮬레이션하여 다이플렉서 특성을 구하고 이를 실현하였다. 제작한 다이플렉서를 실험한 결과 기존의 균등한 선간 간격 배열 구조에서의 특성보다 선간 간격을 각기 다르게 한 경우 통과 대역에서 평탄 특성이, 저지 대역에서는 감쇠량이 약 15dB이상 개선되었음을 확인하였다.

Transmission line characteristics in microstrip line is used to in this paper. 5-microstrip lines composed of various spacing between them suggests characteristics of a diplexer in simulation. By applying the simiulation results, the diplexer realized shows better results of flat responses in bandpass characteristics and bandstop characteristics around 15 dB than symmetric spacing one.
