Abstract
By using the principles of the three line coupled, the equivalent admittance parameters of the band-stop filter of the three line two port spurline for MIC are derived. The frequency and in/output impedance characteristics of the filter were studied. One-section spurline bandstop filter with their stopband cented near 4GHz have been fabricated and tested. The results show good agreement between the theoretical centre frequency and the experimental results.
3선 결합선로의 원리를 이용하여 MIC를 위한 3선 2포트 Spurline으로 구성된 대역소거여파기의 등가 어드미턴스를 구하고 주파수및 입, 출력 임피던스 특성을 조사하였다. 소거내역의 중심주파수를 4GHz로 하는 대역소거 여파기를 제작, 실험한 겨로가 중심주파수의 이론치와 잘 일치하는 좋은 특성을 보여 주었다.
