Abstract
A power recovery system includes a transmission line that is coupled to transfer an RF signal received via an antenna. The RF signal generates a partial standing wave in the transmission line and the transmission line has at least one standing wave anti-node. A power recovery circuit converts an anti-node signal from the at least one standing wave anti-node to a power signal.
