| 摘 要： | 设计了一款适用于手机的小型化WLAN天线,尺寸为10 mm×35 mm,天线的主要结构为一个折叠型倒L-L结构.设计过程中采用了共面波导馈电（CPW）技术,有效地增加了天线的带宽.仿真结果表明,天线在2.45 GHz时覆盖了2.38 GHz ～ 2.688 GHz,5.2 GHz时覆盖了4.77 GHz～6 GHz,同时达到了IEEE 802.1 1a和IEEE 802.11 b/g标准.整体来说,天线尺寸小、频带宽,方向图性能良好.对天线进行了实物加工并进行了测试,结果显示仿真与实验结果吻合,均能覆盖所需频段.

| Abstract: | A small-size dual-band WLAN antenna has been designed. The size of the antenna is only 10 mmx 35 ram. The main part of the antenna is a folded inverted L-L structure. In order to broaden the bandwidth, CPW feeding technology has been used. Numerical simulation results show that the antenna can cover 2.38 GHz - 2. 688 GHz in 2.45 GHz and 4.77 GHz - 6 GHz in 5.2 GHz, which can cover both IEEE 802.11 a and IEEE 802.11 b/g standards. The size of the antenna is compact and has wide bandwidth, and the overall performance of the antenna radiation pattern is good. The proposed antenna is fabricated and tested. The measured and simulated results are matched well, which means that the anten- na designed can cover the desired bands. |
