A 5.80 GHz Harmonic Suppression Antenna for Wireless Energy Transfer Application

Abstract

In this paper, a simple structure based hexagonal microstrip-patch antenna has designed for wireless energy transmission. In this proposed structure, spurious harmonic suppression has achieved by using H shaped slot, defected ground structure (DGS) and open stub. Spurious frequencies has suppressed up to fourth harmonics. Designed antenna is compact size, operating frequency is 5.8 GHz and 10 dB return loss impedance bandwidth of 5.48-6.08 GHz (10.38%) simulated gain of 3.8 dB and radiation efficiency of more than 79% have also been achieved from the designed structure. Because of its fruitful properties, this antenna is well suited for wireless energy transfer applications.
