摘要
用变分法分析了变形圆贴片微带天线主模的谐振频率特性,用瑞利—里兹法(Rayleigh-Rits)确定其本征值和本征函数,理论值与实验值吻合得很好。这种方法适用于任意形状的微带天线元。文末,分析和讨论了几种变形圆贴片微带天线主模的谐振频率。
The fundamented modle resonance frequency of deformed circular microstripantennas is analyzed with the variational method.Eigenvalus and eigenfunction are deter-mined using the Rayleign-Rits method,The numberical examples are compared with experimen-tal results,the agreement is very good.This method can be used for an arbitrarily shapedmucrostrip antenna element.Finally.the resonance frequencies of deformed circular microstripanternna elements are calculated with the method.
