Abstract

In this paper, the effect of slot antenna's location in the radiation performance and impedance bandwidth was analyzed. The proposed antenna was designed to operate at Wi-Fi band(2.4~2.5 GHz) when the slot antenna is located at the center of the ground plane, the proposed antenna has a bandwidth of 340 MHz(2.24~2.58 GHz) under voltage standing wave ratio of = 2 and achieves average realized efficiency of 69 % over Wi-Fi bands.

본 논문에서는 PCB 몸체에서의 슬롯 안테나의 위치가 변할 때 안테나의 방사 성능의 변화가 발생하게 되는 이유에 대해 분석하고, 슬롯의 위치에 따라 대역폭 및 안테나 효율에 미치는 영향을 살펴보았다. 본 논문에서 제안되는 슬롯 안테나는 Wi-Fi 대역에서 동작되도록 설계되었으며, PCB 몸체에서 슬롯 안테나가 PCB 몸체 중앙에 위치할 경우, Wi-Fi(2.4~2.5 GHz)에서 -10 dB 기준 340 MHz(2.24~2.58 GHz)의 넓은 대역폭과 69 %의 높은 안테나 평균 효율을 얻을 수 있음을 확인하였다.
