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.

An integrated circuit comprising:
- an antenna;
- an RF receiver;
- a transmission line, coupled to transfer an RF signal received via the antenna, the RF signal generating a partial standing wave in the transmission line, the transmission line having at least one standing wave anti-node;
- an impedance matching circuit, coupled to the transmission line and the RF receiver, the impedance matching circuit having impedance matching characteristics that support the production of the partial standing wave having at least one peak;
- and
- a power recovery circuit, coupled to the at least one standing wave anti-node that corresponds to the at least one peak, for converting an anti-node signal from the at least one standing wave anti-node to a power signal.
