Rectifier analysis for Radio Frequency energy harvesting and Power Transport

2012 42nd European Microwave Conference, 2012
Wireless Power Transmission (WPT) is an attractive powering method for wireless sensor nodes, battery-less sensors, and Radio-Frequency Identification (RFID) tags. The key element on the receiving side of a WPT system is the rectifying antenna (rectenna) which captures the electromagnetic power and converts it to the electric power.
