摘要

利用热弹性光学指示显微镜(TEOIM)技术,在1.575~GHz波段观测了GPS贴片天线的微波近场分布。实现了天线辐射的可视化,根据与天线表面的距离和光学指示器描述电磁场强度和分布。将实验数据与仿真结果进行了比较,两者吻合较好。讨论了TEOIM系统的可能应用。

IMAGING OF MICROWAVE NEAR-FIELD DISTRIBUTION OF GPS PATCH ANTENNA
Microwave near-field distribution of the GPS patch antenna was visualized by a thermo-elastic optical indicator microscopy (TEOIM) technique at $1.575~GHz$. Visualization of the antenna radiation is realized to describe the electromagnetic field intensity and distribution depending on the distance from the antenna surface and optical indicator. Experimental data was compared and confirmed with simulation results, which are in good agreement. Possible applications of the TEOIM system were discussed.
