Abstract	5.8GHz circularly polarized single element patch antenna and 2×2 antenna array for RF energy harvesting were designed and fabricated. A comparison between Schottky diode and LTC5535 for RF energy harvesting rectenna (rectifying antenna) was analyzed at WLAN frequency of 5.8GHz. Both rectennas are printed on Rogers 4003C substrate. Maximum gain at boresight tip was measured to be 3.4dBi and 8.0dBi for circular polarized single element patch antenna and array patch antenna respectively. And the measured return loss of the two types of antennas was measured to be −10.3dB and −20.3dB respectively. The maximum output DC voltage reading is 72.5mV for Schottky diode and 428.3mV for the LTC5535 rectifier, at a distance of 15cm from the transmitting reference antenna.
