초록

본 논문에서는 하이브리드 balun을 갖는 계산가능 다이폴안테나의 안테나 인자 특성을 모멘트법과 기전력법으로 계산하여 비교하고 있다. 안테나 인자의 표현식은 전력부정합손실의 개념을 적용하여 도출한 식을 사용하였으며, 안테나 인자의 계산에서 나타나는 안테나의 입력 임피던스 및 유효길이는 모멘트법과 기전력법을 적용하여 계산하고 있다. 그 결과, 모멘트법과 기전력법에 의한 입력 임피던스 특성은 최대 17 ${\Omega}$ 정도의 차이가 발생하지만, 안테나 인자 특성은 0.24 dB 이내에서 일치하고 있음을 알 수 있었다.

This paper presents a comparison of antenna factor characteristics computed by the Method of Moments(MoM) and the electromotive force(EMF) method for a calculable dipole antenna with a hybrid balun. An expression for the antenna factor is formulated using the concept of power mismatch loss. The input impedance and effective length of the antenna, which are in the formula of the antenna factor, are calculated using the two methods. The results show that the antenna factors are agreed within 0.24 dB, although the maximum difference between the input impedances obtained from the two methods is about 17 ${\Omega}$.
