Abstract :
A suspended planar patch antenna is presented for ISM band (2.4-2.485) GHz applications. This antenna can be used for wireless energy transfer as proposed in this paper. The radiating patch of the suspended patch antenna is placed over a ground plane at a height and is fed by a coaxial probe. The dielectric medium between the radiating planar patch and the ground plane is air. Suspended planar patch antenna design equations are validated by simulated and experimental results. The radiation patterns are measured in E-plane and H-plane. The analysis is performed using Method of Moments (MOM) simulation software (Zeland- IE3D version 12.0) and the experimental results are obtained from the network analyzer and radiation measurements are done in anechoic chamber. The proposed antenna provides S11 of -45dB, gain of 9.78 dBi with radiation efficiency of 99% at 2.45GHz resonant frequency. Wireless energy transfer is verified by measuring transmitted and received power using power meter with Friis transmission equation.
