Abstract

Even if use ICS repeater in radio communication system, distance between Donor antenna and Service antenna though do much isolation degree must that shortcoming have. Proposed IP antenna to supplement this shortcoming in this paper. Result Doner antenna and isolation of Service antenna that measure through examination do 1.5m and when did direction 180 degree, Isolation confirmed that is measured 110dB. Confirmed that can unuse ICS repeater through this result and service by general RF repeater.

무선통신시스템에서 ICS 중계기를 사용하더라도 Donor 안테나와 Service 안테나의 사이의 거리를 많이 이격시켜야 격리도를 확보해야 하는 단점을 가지고 있다. 본 논문에서는 이러한 단점을 보완하기 위해 IP 안테나를 제안하였으며, 시험을 통해 측정한 결과 Doner 안테나와 Service 안테나의 이격거리를 1.5m로 하고 방향을 180도로 하였을 때 격리도는 110dB 확보됨을 확인하였다. 이 결과를 통해 ICS 중계기를 사용하지 않고 일반 RF 중계기만으로도 서비스할 수 있음을 확인하였다.
