초록

본 논문에서는 고정형 위상천이기를 이용한 동위상 급전 평면형 전력분배기 회로를 제안하였다. 정교한 빔 조향을 위한 위상배열안테나의 집적도가 높아짐에 따라, 소자 안테나에 동일한 위상 신호를 공급하기 위해 급전 선로의 길이를 조정하는 기존의 방법에는 공간적 제약이 존재하게 된다. 따라서 평면형 위상천이 기능을 갖는 결함접지구조를 이용하여 인위적인 급전선 길이 조정 없이 소자 안테나에 동일 위상 신호를 공급하는 전력분배기를 설계하였다. 결함접지구조는 선로의 삽입손실을 최소화하고, 위상 천이를 조절할 수 있도록 설계되었으며, 안테나 포트간 격리도와 평면형 구현이 가능한 분배기를 설계 제작하였다.

In this paper, a planar equi-phase power divider is proposed using fixed phase shifters. As the integrability of a phased array antenna increases for accurate beam steering, a conventional method to excite equi-phase signals to all element antennas, extending the feedline, has spatial limitations. Therefore, the planar equi-phase power divider is designed using a defected ground structure with a planar phase shift function without intentional feedline extension. The defected ground structure has been considered for a low insertion loss and a controllable phase shift, whereas the power divider has been designed and implemented with a port-to-port isolation and a planar configuration.
