摘要：

提出了一种工作在GSM/DCS/PCS/UMTS/HIPERLAN/2 以及IEEE 802.11 a 频段的五频平面倒F天线的改进形式。该天线结构通过在主辐射贴片以外的容性寄生贴片末端增加延展，改变天线工作的自然模，对多个谐振器进行参差调谐以覆盖感兴趣的频率范围，达到寄生耦合以控制带宽。同时，容性寄生贴片末端的延展部分相当于增加了堆栈的寄生贴片，从而实现多频工作。改进的天线形式满足在所有5个频段内的S11＜-10 dB。利用FDTD方法对该天线进行了仿真，仿真结果与实验结果一致。

Abstract:

An improved penta-band planar inverted-F antenna design for mobile devices at those bands of GSM/DCS/PCS/UMTS/HIPERLAN/2 and IEEE 802.11a is presented. The main improvement was to increase the horizontal part of capacitor so as to control bandwidth which covers the interest frequency ranges by coupling, and also multi-frequencies was achieved due to the parasitic stacked elements to the patch correspondingly, resulting in the realization of penta frequencies with S11< -10 dB. FDTD method was also used for the antenna simulation, and as well as perfect agreement was achieved with experiments.
