(54) Title: COVERAGE AREA ADJUSTMENT TO ADAPT SATELLITE COMMUNICATIONS 1-1 (57) : The described features generally relate to adjusting a native antenna pattern of a satellite to adapt communications via the 71- 01 N coupled between the feed array assembly and the reflector. The feed array assembly may have a plurality of feeds for communicating satellite. For example, a communications satellite may include an antenna having a feed array assembly, a reflector, and a linear actuator signals associated with a communications service, and the reflector may be configured to reflect the signals transmitted between the feed O 01 array assembly and one or more target devices. The linear actuator may have an adjustable length, or otherwise provide an adjustable 1-1 position between the feed array assembly and the reflector. By adjusting the position of the feed array assembly relative to the reflector, 00 the communications satellite may provide a communications service according to a plurality of native antenna patterns. 1-1 O C [Continued on next page] WO 2018/190794 Al MIDEDIMOMOIDEIREEMOMOHMONEHOHIMEIS (84) Designated States (unless otherwise indicated, for every kind of regional protection available): ARIPO (BW, GH, GM, KE, LR, LS, MW, MZ, NA, RW, SD, SL, ST, SZ, TZ, UG, ZM, ZW), Eurasian (AM, AZ, BY, KG, KZ, RU, TJ, TM), European (AL, AT, BE, BG, CH, CY, CZ, DE, DK, EE, ES, FI, FR, GB, GR, HR, HU, IE, IS, IT, LT, LU, LV, MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
