Study on an S-Band Rectenna Array for Wireless Microwave Power Transmission
Microwave Power Transmission (MPT) system is to wirelessly transmit microwave power from one location to another, in which the transmitted microwave power is received and converted to DC power. The microwave power transmission is an approach for wireless power transmission. As an important component of a microwave wireless power transmission systems, microwave rectennas are widely studied. A rectenna based on a microstrip dipole antenna and a microwave rectifier with high conversion efficiency was designed at 2.45GHz. The dipole antenna achieved a gain of 5.2dBi, a return loss greater than 10dB and a bandwidth of 20%.
