A Design of a Compact Low Power Rectenna Based on Microwave Power Transmission

摘要

Microwave power transmission (MPT) is a new type of wireless energy transmission with broad prospects. The research on it has been one of the most active topics in the world. Rectenna is a key component of the MPT system, as well as the main direction of research at home and abroad. At present, most researches on rectennas are large-scale array antennas, of which the rectification efficiency performs well, but the design and implementation can be complicated. For this reason, in this paper, we design a simple meander dipole rectenna of 2.45 GHz for compact and low power, with a rectification efficiency of 40.5%, which is appropriately applied to most compact wireless energy transmission equipment.
