Abstract: A phased-array antenna system includes: an array of discrete antenna modules disposed conformally with an exterior surface of a platform; a digital distribution system comprising a digital communications medium to convey digital signals to and/or from respective input/output ports of the antenna modules; and a controller system to supply and/or receive the digital signals to/from the antenna modules via the digital distribution system. The controller system controls relative phases of the digital signals to enable the antenna elements to form a directive antenna beam pattern. Each antenna module includes: an antenna element to emit and/or absorb RF signals; an input/output port to send and/or receive digital signals; an electronics unit including an A/D and/or D/A converter to provide an interface between the antenna element and the input/output port; and a housing in which the antenna element and electronics unit are packaged.
