Abstract

We analyze the radiated emission and mutual coupling problem from a single microstrip transmission line and double signal traces with various ground patterns. In this paper, it is shown that the reduction of the radiated emission from the signal traces can be accomplished by using the novel and compact patterns on the ground planes in a specific frequency band. The accuracy and validation of radiation mechanism from the transmission line on a novel ground plane are evaluated and explained by using a commercially available software and experiment, respectively.

본 논문에서는 다양한 접지면과 함께 단일 신호 선로 및 복수 신호 선로로부터의 복사성 방사 레벨과 신호간 커플링 현상을 관찰하고 좁은 접지면과 새로운 패턴을 이용하여 일정한 주파수 대역에서 신호 선로로부터의 복사성 방사 레벨의 감소를 얻을 수 있음을 접지면의 최적화 과정과 함께 기술하고 있다. 다양한 접지면과 함께 윗층에 설치된 신호 선로로부터의 복사 메커니즘의 예측 및 해석의 정당성을 각각 상용 소프트웨어와 실험을 통하여 검증하였다.
