Popis: In this paper a planar rectenna (rectifier + antenna) design which is the crucial part in a microwave power transmission system is presented. The developed structure is suitable to harvest RF energy at 5.8GHz ISM frequency band for powering devices involving low power consumption, located in unreachable area or needing expensive maintenance costs. The proposed design incorporate a 2 × 2 circular polarized antenna array with an enhanced directivity of about 10.2 dBi and an overall size of 14.6 × 8 cm2 built and carried out by using CST Microwave Studio software. The receiving antenna is associated with a microstrip rectifier that combines series and shunt configuration employed Schottky diode HSMS2852 and HSMS2850. The RF-to-DC rectifier circuit is designed and simulated by using schematic simulation in ADS software. An output DC voltage of 2.2 V and a RF-to-DC conversion efficiency of more than 70% were achieved with an optimum load resistance of 6 kΩ for 0 dBm microwave incident power level.
