초록

본 논문은 격리도가 향상된 US-PCS 대역 댁내용 중계기 안테나를 제안하였다. 일반적으로 중계기는 송신신호와 수신 신호 사이의 간섭을 줄이기 위해 격리도 확보가 필요하다. 그러므로 선형 편파 특성이 우수한 IBD(Integrated Balun Dipole) 안테나에 편파 다이버시티 기법과 캐버티, 멀티 캐버티, 개구정합 방법을 사용하여 안테나의 전후방비 개선을 위한 연구를 하였다. 시뮬레이션과 측정을 통해 개구 정합 방법과 편파 다이버시티 기법을 동시에 사용한 안테나는 US-PCS 대역에서 VSWR < 1.5의 대역폭, 8 dBi 이상의 이득, 그리고 약 15$\~$24dB의 격리도 개선효과가 있음을 확인하였다.

This paper presents an antenna for US-PCS band indoor repeaters with enhancement of isolation. In common repeaters require an enough isolation to reduce the interferences between transmitted and received signals. Thus, it is investigated to improve front-to-back ratio of IBD(Integrated Balun Dipole) antenna which has a good linear polarization with a cavity or multi-cavity by using polarization diversity and aperture matching method. From the simulated and measured results, the antenna realized by using polarization diversity and aperture matching method has a VSWR below 1.5, gain over 8 dBi and enhanced isolation of 15$\~$24 dB in US-PCS band.
