Abstract :
A candidate High Gain Antenna (HGA) architecture for NASA´s Europa Clipper mission is presented. The HGA is a dual reflector antenna system composed of an Axially Displaced Ellipse (ADE) geometry with an X/Ka-band feed. In this investigation an array feed composed of four X-band horns surrounding a Ka-band feed is investigated as a low-cost feed option.
