Self-biased Receiver System


Background: Conventional rectenna systems have been developed for large power reception and efficient power conversion. Applications of this technology are typically large power transfer systems which require a large-scale array. Technology Description: This innovation is the first rectenna technology proposed for small-scale personal use. The device receives a microwave or RF signal sent by a transmitter and the received power is delivered to a microwave or RF receiver and also to a rectenna. The receiver recovers the transmitted data or voice signals while the rectenna generates DC power to be supplied to the receiver. This reduces the demand on the DC power supply which results in longer battery life. Applications: Low power short-range wireless sensors such as: RF Tags Security access systems.
