Antenna transceiver system

Provided is an antenna transceiver system for transmitting and receiving voice, digital data, radar and IR signals, and for processing received signals for use by an operator. The system includes an antenna array having a plurality of radiating elements, each element connected to a transmit/receive ("T/R") module. Each T/R module includes phase shifters, as well as a phase conjugation module for transmitting a return signal to a location along a beam path of an incoming signal. Transmission of the return signal does not require knowledge of the location of either the signal source or the antenna transceiver system. The antenna transceiver system is disposed on a plurality of vertically aligned planes integrated into a compact unit. The units can be embedded in headgear of a user, allowing for hands-free operation of the system. Alternatively, the antenna transceiver system can be integrated into a vehicle, man-transportable backpack, or other designated platforms.
