Abstract

A compact dual-fed circular polarization (CP) antenna array with reflector is designed for radio frequency (RF) energy harvesting system. The antenna composed four patches with dual slots are placed underneath of radiating patches to reduce the antenna´s sizes while the reflector is use to reflect the back radiation as well increase the gain. A narrow bandwidth (2.47 GHz - 2.53 GHz) with good axial ratio (AR) bandwidth (2.47 GHz - 2.49 GHz) and gain of 6.73 dB is presented. This antenna is suitable for application of WiMAX and rectenna for energy harvesting system.
