Abstract

For WLAN dual-band operation, a modified Yagi dipole antenna is presented. The modified dipole antenna consists of a dipole antenna with open sleeves and parasitic elements. The parasitic elements are used for the practical application of the radiation patterns and high-gain operation at the WLAN dual band. The experimental results showed that the achieved impedance bandwidths were 320 MHz (2.4 to 2.72 GHz) and 640 MHz (5.04 to 5.68 GHz), respectively. The measured maximum gain at the two WLAN bands was 7.74 dBi and 6.93 dBi, respectively.

WLAN 이중 대역 동작을 위한 수정된 야기 다이폴 안테나를 제안하였다. 제안된 안테나는 오픈 슬리브 다이폴안테나와 기생소자들로 구성되었다. 각 WLAN 동작 대역에서 오픈 슬리브의 영향, 방사 특성, 그리고 기생소자의 영향에 관하여 분석하였다. 측정 결과 제안된 안테나의 임피던스 대역폭은 320 MHz (2.4 - 2.72 GHz)와 640 MHz (5.04 - 5.68 GHz)이고 각 WLAN 대역에서의 최대 이득은 7.74 dBi와 6.93 dBi이다.
