摘要
The new stacked-patch endfire antenna is proposed for wireless fidelity (WiFi) access point and base station. The proposed using three copper patches is presented. The new antenna uses easily fabrication. The advantage of the endfire antenna with three patches compared to the conventional Yagi antenna is a reduction in the length of the antenna and the dimension of the antenna is 0.504 lambda x 0.664 lambda x 0.075 lambda mm(3) The antenna has a gain of 9 dB, return loss better than - 10 dB around the WiFi band from 2.4 GHz to 2.483 GHz and the front-to-back can achieve 15 dB. We described the antenna structure and presented the comparison of simulation results with experimental data. The proposed antenna is fabricated, and measured reflection coefficient, radiation patterns, and gain are presented.
