Abstract
In this paper, the feed network for PCS base station antenna was designed using ADS. To verify the design results, feed network with 8-ports was fabricated and the calculated results were compared with measured results. The measured results showed good agreement with calculated results. As results of measurements, return loss of -30dB is achieved at res band. The designed feed network could used as the feed network of base station antennas.
본 논문에서는 PCS대역(1,750 MHz ${\sim}$ 1,870 MHz)에서 동작하는 급전회로를 ADS (Advanced Design System)를 이용하여 설계하고, 설계된 결과로부터 급전회로의 구조 값을 결정하였다. 설계된 급전회로의 타당성을 검토하기 위하여 8포트 급전회로를 실제 제작하고 반사손실을 측정하여 계산 값과 비교하였다. 측정결과 반사손실은 -30dB 이하를 만족하였으며 본 논문에서 설계한 급전회로는 이동통신 기지국용 안테나의 급전회로를 사용할 수 있을 것으로 생각된다.
