Abstract
A multi-beam antenna (MBA) system for a spacecraft, the MBA system including a reflector and a feed array of radiating feed elements configured as a phased array and illuminating the reflector. The feed array includes a plurality of interchangeable modules. Each of the plurality of interchangeable modules includes a distal mounting panel and a proximal mounting panel, and at least six feed array elements. Each feed array element is electrically coupled with a respective amplifier and mechanically coupled with an exterior surface of the distal mounting panel. The respective amplifiers are thermally coupled with the proximal mounting panel and are mechanically coupled to an interior surface of the distal mounting panel and an exterior surface of the proximal mounting panel. An interior surface of the proximal mounting panel of each interchangeable module is mechanically and thermally coupled with a back plate.
