Scattering Study of Microwave Transmitted From a Patch Antenna On an Object Embedded in a Dissipative Medium

This report presents the power pattern calculated by HFSS for the RF-microwave transmitted from a low profile inexpensive small patch antenna and scattered by a spherical object embedded within the confines of cuboid dissipative medium. The localization of the object causes the alteration of the radiation power pattern as well as the efficiency of the antenna. The calculation results indicate a patch antenna can be applicable to microwave image study identifying the presence of an object embedded in a dissipative material.
