摘要

研究了任意各向异性介质基板上的矩形微带贴片天线问题。采用完全匹配层吸收器时域有限差分法(FDTD)确定了该结构的时域场响应、回波损耗、输入阻抗和辐射方向图。此外，还研究了给料机位移的影响。用PML的时域有限差分法得到的结果与已发表的数据吻合较好。

FDTD analysis of a rectangular patch antenna on a general uniaxial anisotropic dielectric substrate

The problem of a rectangular microstrip patch antenna on arbitrary anisotropic dielectric substrate is treated. The finite-difference time-domain (FDTD) method with perfectly matched layer absorber (PML) is applied to determine the time domain field response, the return loss, the input impedance and the radiation pattern of the proposed structure. In addition, the effect of feeder displacement is studied. The results obtained by the FDTD with PML are found to be in good agreement with the published data.
