Abstract: This paper presents a planar rectenna (rectifier + antenna) design at 2.45 GHz ISM band for microwave power transmission for powering devices involving low power consumption, located in unreachable area or needing expensive maintenance costs. The proposed design incorporate a 3×3 circular polarized antenna array with an enhanced directivity of 9.14 dBi and an overall size of 26.18×11.86 cm2 modeled by using CST Microwave Studio software, and associated to a microstrip rectifier based on a voltage doubler circuit with HSMS 2822 Schottky diode designed and simulated by using schematic simulation in ADS. A high conversion efficiency of 71% and a DC output voltage of 10V can be reached for a given input power level of 20 dBm with an optimum load of 1500 Ω.
