| 摘 要： | 从微带天线腔模法出发,结合叠加原理,提出了加载短路钉微带天线中,同轴馈线内部导线和加载的短路钉上电流比的概念。并利用此概念来分析加载短路钉微带天线内部的电磁场分布和谐振特性、阻抗特性以及辐射特性等。本文给出了加载单个短路钉矩形微带天线的分析,并将本文结果和Zeland软件的仿真结果进行对比,加载短路钉可以以较小天线尺寸实现较低谐振频率,验证了本文方法的有效性。

| Abstract: | Based on cavity model of microstrip antenna and the principle of superposition,the concept of the ratio between the currents on the inner conductor of fed-coaxial line of a microstrip antenna and shorting-pin is proposed here.The distribution of electromagnetic field inside a microstrip antenna as well as the characteristics of resonance and impedance and radiation of the microstrip antenna are analyzed by means of the ratio.A microstrip antenna loaded with one shorting-pin has been analyzed.Comparisons between presented results and IE3D results have shown the efficiency of presented method,small size of the antenna ledds to the low resonance. |
