초록

본 논문에서는 LMDS용 평변형 안테나로 28 GHz에서 동작하는 LTS 안테나와 Vivaldi 안테나를 시간영역 유한차분법(Finite Difference Time Domain Method)를 이용하여 최적화한 후 제작 및 측정하였다. 부엽의 크기 를 줄이기 위하여 corrugation 구조를 설계한 평변형 안테나에 적용하여 FDTD 방법으로 최적화 한 후, 제작 및 측정하였다. 측정결과, corrugation 구조를 갖는 LTS 안테나와 Vivaldi 안테나의 부엽의 크기가 약 4 dB 감소됨을 확인하였다.

In this paper, the planar LTS and Vibaldi antenna operating at 28 GHz for LMDS is optimized by finite difference time domain(FDTD) method and then fabricated and measured. We designed LTS and Vivaldi antenna with corrugation structure for reducing sidelobe, then these antenna are optimized by FDTD, and then fabricated and measured. In a results of the measured values, sidelobe level of LTS and Vivaldi antenna with corrugation structure is 4 dB lower than that of LTS and Vivaldi antenna.
