ABSTRACT:
There is disclosed an electronic steering circuit suitable to be utilized in scanning antenna array systems for automatically steering receive and transmit signals between particular antenna elements and a plurality of transceivers. In the preferred form, the electronic steering circuit is coupled between each one of a plurality of antenna elements and a lens, such as a Luneberg lens. Each steering circuit is adapted to be connected to a particular transceiver. Transmitted signals from the transceiver are routed through the steering circuit to the lens and cumulated receive signals from the lens are routed through the steering circuit to the transceiver.
