초록

본 논문에서는 벨리미터파대 linear tapered slot (LTS) 안테나와 linear constant tapered slot(LCTS) 안테나를 시간영역 유한차분법(FDTD)을 이용하여 최적화한 후. 제작하고 측정하였다. 급전구조로 $\lambda$/4 개방 스터브의 폭을 확장시킨 microstrip-to-slot transition을 사용하여 대역폭이 16.5 GHz(VSWR~2)의 광대역 특성을 갖도록 제안하였다 제작된 안테나의 해석값과 측정값을 비교한 결과 LTS 안테나의 대역폭이 각각 8.3 GHz (26.47%)와 7.1792 GHz(22.44 %) 였고. LCTS 안테나의 대역폭은 각각 8.1 GHz(26.47 %)와 6.3243 GHz(20.43 %)의 우수한 대역폭을 얻을 수 있었다.

In this paper, the linear tapered slot(LTS) antenna and linear constant tapered slot(LCTS) antenna are optimized for millimeter-wave antenna by the finite difference time domain(FDTD) method and then fabricated and measured. The microstrip-to-slot transition is proposed with the widen $\lambda$/4 open stub as feeder for wide bandwidth of 16.5GHz($VSWR\leq2$). The results of the calculation and measurement, the bandwidth of LTS antanna is 8.3GHz(26.47%) and 7.1792GHz(22.4%) respectively. Also, the bandwidth of LCTS antenna is 8.1GHz(26.47%) and 6.3243GHz(20.43%) respectively.
