초록

본 논문에서는 composite right- and left-handed (CRLH) 전송선로를 이용한 나선구조 zeroth-order resonance (ZOR) 안테나가 제안되었다. 안테나의 영차공진특성은 주기구조의 분산특성에 의해 이론적으로 분석되었다. $2{\times}2$ 나선구조 안테나의 크기는 $0.155{\lambda}_{0}{\times}0.155{\lambda}_{0}$이며 CRLH 전송선로의 병렬 인덕턴스 값이 증가함으로 인해 제안된 안테나의 크기는 일반적인 버섯구조 ZOR 안테나보다 65%의 크기를 감소시킬 수 있었다. 또한, 제안된 안테나의 방사특성은 버섯구조 ZOR 안테나와 비슷한 전방향성 방사특성을 가짐을 확인하였다.

In this paper, the spiral zeroth-order resonance (ZOR) antenna using composite right- and left-handed (CRLH) transmission line is proposed. The zeroth-order resonant characteristics of the antenna are described by dispersion relation of a periodic structure. The size of the $2{\times}2$ spiral ZOR antenna is $0.155{\lambda}_{0}{\times}0.155{\lambda}_{0}$. By increasing shunt inductance of CRLH transmission line, the size of this antenna is reduced by 65% compared with that of a mushroom ZOR antenna. The radiation pattern of this antenna have omnidirectional pattern which is similar to that of mushroom ZOR antenna.
