摘　　要：本文用FDTD全波分析法研究了双极化方形贴片单元的物理参数,即馈线宽度、相对介电常数和基片厚度对天线谐振频率、反射系数和隔离度的影响.比较了这些参数对二元阵和单元性能影响的不同,同时研究了阵列互耦随天线参数的变化情况.The effects of dual - polarized square patch antenna physical parameters, such as the width of feedline, the relative dielectric constant and the depth of the substrate, on the antenna resonant frequency, reflection coefficient and isolation are analyzed by the FDTD method. The different effects of these parameters on the two - element array performance are compared with those of the single element. The variances of the array coupling with its parameters are also studied.
