提出了一种微带馈电式圆形微带天线设计方案，通过在辐射贴片表面加载月牙型缝隙，改变电流有效路径，实现多频特性。通过HFSS仿真分析缝隙形状对天线性能的影响。结果表明，天线工作的三个频段相对带宽分别为4.1%(2.39~2.49 GHz)，3.98%(3.92~4.08 GHz)和3.75%(5.51~5.72 GHz)。其中低频和中频段的最高增益达到6.58 dB和5.01 dB。天线尺寸为35 mm×52 mm，具有小体积、高增益、全向性良好的特点，能够应用于无线通信系统中，并且这种结构简单、参数少、多频段的设计方法为天线设计提供了新的途径。

A design of circular microstrip antenna with microstrip feed was presented. By loading crescent-shaped slot, the current effective length was changed and the antenna obtained the multi-frequency characteristics. The slot’s impact on performance of antenna was analyzed by HFSS software simulation. Three relative bandwidths are 4.1% (2.39-2.49 GHz), 3.98% (3.92-4.08 GHz) and 3.75% (5.51-5.72 GHz), respectively. And the maximum gain of low frequency and mid-frequency are up to 6.58 dB and 5.01 dB. The antenna has a dimension of 35 mm×52 mm and the characteristics of small volume, high gain and omni direction. It can be applied in wireless communication system. Moreover, this multi-frequency design with simple structure and less parameters provides a new way for antenna designs.
