Abstract

In this paper, a Four-wired antenna was designed and manufactured using Four-wires in order to perform EMI/EMC experiments. As compared with a TEM cell, the feature of the Four-wired antenna has simple installment with broadband balun, a Four-wired antenna, and loading resistances in an anechoic chamber. And the E-field polarization of antenna can be easily changed. Without the limitation of space, EMI/EMC experimental environment could be built within the anechoic chamber with the moderate cost. In S, C, and X-bands, the manufactured antenna was able to make an experiment on EMI/EMC with the DUT which has the quiet zone of the height, width, length equal to about 10 cm.

본 논문은 Four-wired 안테나를 이용하여 EMI/EMC 실험을 할 수 있는 안테나를 설계, 제작하였다. 일반 TEM-cell과 비교하여 이번 논문에서 설계, 제작하는 안테나의 특징은 무반향실에 broadband balun, Four-wired 안테나와 Loading resistances을 쉽게 설치하여, E-field polarization을 선택 할 수 있다는 점이다. 그리고 공간의 제약없이 기존의 무반향실을 이용하여 적은 비용으로 EMI/EMC 실험 환경을 구축할 수 있다. 제작된 안테나는 S, C 및 X-band에서 EMI/EMC 실험을 할 수 있는 가로, 세로, 높이 모두 약 10 cm 정도의 크기를 갖는 quiet zone을 얻을 수 있었다.
