Abstract
A Method and system for remote power distribution and networking for passive devices is provided. In this regard, a sensor comprising a leaky wave antenna may be powered utilizing energy from a radio frequency signal received via the leaky wave antenna. The sensor may be operable to recover a baseband signal from the received radio frequency signal. The sensor may be operable to generate one or more sensor readings in response to the received baseband signal. The sensor may be operable to communicate the sensor reading to a source of the received radio frequency signal via a backscattered signal. The backscattered signal may be generated by controlling spacing between surfaces of the leaky wave antenna. The backscattered signal may be generated by switching a load in and out of a receive path of the sensor and/or by switching between a plurality of feed points of the leaky wave antenna.
