Accurate Computation for Resonant Frequency of Rectangular Microstrip antennas with Multi-Layer Dielectric

本文将谱域导抗法推广应用于计算多层介质覆盖矩形微带天线的谐振频率。通过引入两种特殊的数值积分方法，解决了二维振荡函数无穷区间积分问题。获得了一些有用的结论。

A numerical method for calculating the resonant frequency of multi-dielectric covered microstrip antennas by means of spectral domain immittance approach is described. Two specific method of numerical integrals are proposed to deal with the chief difficulty. A rectangular patch has been fabricated and measured. The numerical results of resonant frequency are in good agreement with experimental data. Some useful conclusions have also been obtained.
