Abstract

In this Paper, the Performance of the semi-anechoic chamber which is to be constructed by the cross-shaped ferrite absorbers with broadband frequency characteristics, has been evaluated by the image method. As a result it was confirmed that the cross-shaped absorber has excellent performance over the frequency range from 30 MHz to 3,000 MHz, while the tile and the gird-type ferrite absorbers have the bandwidth of 30 - 1,000 MHz.

본 논문에서는 광대역 특성의 십자돌기형 페라이트 전파흡수체로 이루어지는 전파 반무향실의 특성을 영상법에 의하여 평가하였다. 그 결과, 그리드형 전파흡수체가 3 ~ 1000 MHz의 주파수 대역폭을 가지는 데 대하여, 십자돌기형 페라이트 전파흡수체는 30 MHz ~ 3,000 MHz의 주파수 대역에서 우수한 특성을 가지는 것을 확인하였다.
