Abstract

The development of microstrip antenna technology is rapid. A microstrip antenna can support RFEH (Radio Frequency Energy Harvesting) implementation. A wideband circular polarization (CP) microstrip antenna at 2.45 GHz is presented. This research offers an antenna with circular patch structure with right and left parts cut off. The ground plane of the antenna is rectangular at the bottom to widen the bandwidth. The simulation and measurement results for return loss are -24.892 dB and -22.975 dB respectively. For axial ratio are 2.209 dB and 0.080 dB respectively. This value close to the ideal value for a wideband CP microstrip antenna
