This research purposed the design of rectenna that it can convert the electromagnetic field source into the DC voltage output. The research is conducted in two steps, simulation and fabrication of antennas, and rectifier circuits. This research applies CST Studio Suite software to simulate the antenna and NI Multisim 14.0 to simulate the rectifier. The antenna has been designed and fabricated by utilizing the array antenna of the circular patch microstrip with adding of the insertion feeder with 7 mm of length and 1 mm of width to reach of the matching antenna. The rectifier has been created by using BAT 85 DO-35 Schottky diode where it can work at high frequency. The measurement result of the antenna is minimum with the return loss amount of 33.783686 dB, bandwidth is 100 MHz, and VSWR (Voltage Standing Wave Ratio) is 1.021669. The rectenna can receive a maximum voltage of 11 mV at a range of 1cm.
