摘　　要：提出一种分析多介质层矩形微带天线的解析方法。首先导出了计算多介质层微带线的等效相对介电常数的显式计算公式，进而得到了多介质层矩形微带天线谐振频率的解析计算公式和一些数值结果。与精确的数值方法结果和实验值作了比较，它们吻合得很好。本方法运算简单，特别适合于ＣＡＤ应用。A simple method is presented to predict the resonant frequency of rectangular microstrip antennas with multidielectric layers.A set of closed form expressions of the effective permittivity is derived firstly for the multilayer microstrip.Then the theoretical resonant frequency and its numerical results are obtained based on a generalized transmission line model of the rectangular microstrip antenna with multilayers. Present results are in very good agreement with those of the full-wave analysis and the experimental results in the literature.Due to the simplicity,the new formulation is suitable for direct application in CAD programs.
