Design of a Hexagonal Patch, Defected Ground Antenna for Energy Harvesting Applications

The design of a wide-band CPW-fed hexagonal antenna for 5.8GHz RF energy harvesting applications is presented in this manuscript. Partial ground with a rectangular slot is used to improve the matching of impedance and gain parameters at the operating frequency. This antenna is designed on a 30×30mm
²
FR4 substrate to make it compact, economical, and robust. The performance parameters, such as reflection coefficient, gain, surface current, radiation pattern, etc., have been presented, which shows the proposed antenna is working fine for the claimed operational bandwidth.
