设计了一种缝隙多频微带天线。通过在微带天线贴片上加载缝隙改变电流分布，从而实现微带天线的多频谐振。用HFSS软件对其进行仿真分析实现参数的优化设计，在1~6 GHz内得到了3个谐振频率：2.43，4.40和5.27 GHz，其回波损耗分别为：–31.84，–32.82，–29.62 dB。当回波损耗小于–10 dB时，相对带宽分别为：3.29%，1.41%，2.05%。该多频微带天线具有体积小、回波损耗低等优点，可用于无线通讯系统。

A multi-frequency slot microstrip antenna was designed. The current distribution on the antenna patch was changed by loading slot on the patch of the antenna, the multiple frequency resonance of the antenna was realized. HFSS software was used to simulate for optimizing the design parameters. Results show the proposed antenna has three resonant frequencies of 2.43, 4.40 and 5.27 GHz, whose return losses are –31.84, –32.82, –29.62 dB, respectively. When the return loss is less than –10 dB, their relative bandwidths are 3.29%, 1.41%, 2.05%, respectively. The proposed antenna has the advantages of small volume, low return loss, it can be used for wireless communication system.
