For future science missions, communication antennas with full azimuth field-of-view are needed. In previous missions, X-band phasedarray antennae (PAA), with an aperture conformal to a cone surface, have been employed. Although such conformal geometries are stillvery promising candidates for future missions, X-band will phase limitations. For one, the tendency towards increased data rates drives the need for increased bandwidth and increased gain. Second, X-band is more and more occupied by terrestrial services so that its availability for future science space missions is at risk. More promising would be a K/Ka-band PAA, but the K/Ka band technologyreadiness is currently too low for space application. For this purpose, an activity is proposed on a deep-space K/Ka band communication antenna development suited for future science missions. An antenna architecture and layout shall be elaborated and justified byfuture mission needs. Radiating elements, subarray structuring and all active beam-forming network elements shall be assessed (SSPAs, LNAs, amplitude phase actuators etc.). A breadboard shall be designed, RF measured and manufactured. As a minimum, the breadboardshall contain all critical elements identified in the design phase and one fully operational subarray. A technology roadmap shall be presented at the end of the activity
