应用于WLAN的宽频带天线设计

摘要

为了设计出可以覆盖无线局域网WLAN的2.4 GHz,5.2 GHz,5.8 GHz三个频带的天线,采用一种结构简单的宽带双频共面波导馈电的单极子天线.该天线由一个平面倒L形和一个倒U形贴片连接构成,实际加工制作了一个天线并且实测了S11参数,结果表明该天线具有两个独立的谐振模式,并且在应用范围内具有良好的阻抗匹配特性.%In order to design the antennas of 2. 4 GHz,5. 2 GHz and 5. 8 GHz which can cover WLAN, a simple monopole antenna with broad band, dual-frequency and CPW feed is presented. It is consisted of inverted L-shaped planar and inverted U-shaped patch element. The structure and Sll parameter are measured. The results show that the antenna has two independent resonance modes, and has well impedance matching performance in application range.
