摘要

介绍了一种适用于无线局域网(WLAN)和笔记本电脑WIFI的小尺寸窄边框天线。天线占地面积仅为38.5×3×0.4 mm3，与200×260 mm2铜板结合，模拟系统地平面。PCB采用直接馈电臂(正面)和耦合臂(底部)的两层双组件。在底部的耦合臂形成1/4-λ基波在2.4 GHz和它的更高模式在5.75 GHz。在前端直接馈电臂形成1/4 λ基波在5.5 GHz。在远场测量中，低频段和高频段的峰值增益和效率分别为1.9 ~ 2.4 dBi和45 ~ 61%。实验结果表明，该天线具有良好的窄板性能。

Small WIFI/WLAN antenna for narrow boarder design

This paper presents small size and narrow border antenna for Wireless LAN (WLAN) and WIFI for laptop. The antenna occupies only 38.5×3×0.4 mm3, and the antenna is combined with 200×260 mm2 copper plate to simulated system ground plane. PCB uses two layer and two components of direct-fed arm (front side) and coupled arm (bottom side). In bottom side couple arm form 1/4-λ fundamental at 2.4 GHz and its higher mode at 5.75 GHz. In front side direct-fed arm form 1/4-λ fundamental at 5.5 GHz. In far field measured, peak gain and efficiency in low and high band are 1.9-2.4 dBi and 45–61 %. Finally, experiments demonstrate that the present antenna exhibits a good performance for Narrow boarder.
