摘　　要：介绍了蝶形微带贴片天线的一种双频设计。基于变分法导出蝶形微带天线谐振频率闭式计算公式 ,采用矩量法对天线进行了全波分析 ,该法比已有方法具有更广的适用范围。最后对设计结果进行了加工和测试 ,测试结果与实验结果相当吻合 ,证实了数值分析与设计方法的有效性。A design of dual-frequency operation for the bow-tie microstrip antenna is proposed. The closed form calculation formula of resonant frequency for the bow-tie microstrip antenna is derived, and the full wave analysis is established by the MoM (method of moments), which has wider application than the method reported in the literature. Based on this design result, a dual-frequency antenna has been fabricated and measured. The measured results and the calculated ones are in good agreement, verifying the validity of this numerical analysis and design program.
