Abstract

This paper designed a compact printed meandered scot antenna which to integrate in wireless LAN and proposed a printed dual meandered slot antenna for improving bandwidth. A printed dual meandered slot antenna is calculated by using the mehtod of FDTD. The calculated results showed good agreement with the measured results. As a result of measurement, the bandwidth(VSWR< 2) of single meandered slot antenna is 115 MHz and the bandwidth of dual meandered slot antenna is 164 MHz. The dual meandered slot antenna bandwidth has been improves to that of 43% comparing to single meandered slot antenna.

무선 LA기 단말기 내부에 집적하기에 적합한 초소형 인쇄회고 형태의 안테나 개발을 위해 미앤더드 슬롯 안테나를 연구하였으며, 인쇄회로형 안테나의 협대역 특성을 개선하기 위하여 이중 미앤더드 슬롯 안테나론 제안하였다. FDTD 방법으로 수치 해석하였으며, 인계된 안테나의 측정치는 해석 결과와 잘 일치하였다. 측정결과, 단일 미앤더드 슬롯 안테나와 이중 미앤더드 슬롯 안테나의 대역폭(VSWR<2)은 각각 115MHz 와 164 MHz 이며, 단일 미앤더드 슬롯 안테나와 비교한 결과, 제안한 이중 미앤더드 슬롯 안테나의 대역폭이 43% 증가됨을 확인하였다.
