Title: Compact phased array antenna system, and a method of operating same

Abstract: An antenna system (10) includes circuitry (13) and an antenna unit (12). The antenna unit includes a multi-layer circuit board (21). The circuitry provides radio frequency signals, control signals and power to the circuit board. The circuit board has an array of antenna elements (23) on one side thereof, and has a plurality of modules (71, 72) soldered to and projecting outwardly from the opposite side thereof. The modules each have electronic circuitry thereon, which is electrically coupled to the circuit board. Each module includes a thermal transfer element (96), the heat generated by the electronic components on that module being thermally transferred by the thermal transfer element to a cooling section (51).
