Abstract

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.
