Abstract
A phased array antenna design that is modular and scaleable in terms of beam quantity, coverage area, and receive sensitivity/transmit EIRP. A modular array building block for an antenna array comprises: a plurality of antenna elements, each antenna element operable to receive and output an electromagnetic wave signal, the antenna elements arranged adjacent to each other, a plurality of antenna element interface assemblies; each antenna element interface assembly coupled to one of the plurality of antenna elements and coupling the received signal to an amplifier, and a plurality of circuit board assemblies, the circuit board assemblies arranged substantially parallel to each other, each circuit board assembly comprising: a plurality of amplifiers, each amplifier operable to amplify a received signal from an antenna element, and a plurality of beamformers, each beamformers coupled to an output of an amplifier, wherein the circuit board assemblies, antenna element interface assemblies and antenna elements are arranged so as to form a module.
