It is presented the design of an electronically steerable medium gain antenne for aircraft able to provide voice communication through satellite. The antenna consists of 5 radiating facets and the cove rages achieved, including the effect of the aircraft fuselage, are based on the experimental results obtained with the actual components of the Beam Forming Network (switches, phase shifters, power dividers) and the radiating facets including the matching network. 100 % of the mandatory coverage (colatitude 0-85 deg) is achieved with a gain greater than 10 dBi and 12 dBi are achieved in 60 % of it. Concerning the goal coverage (colatitude 0-105 deg) a gain greater than 7 dBi is achieved in 84 % of it. The dimensions of the radome required for this antenna are: length 1780 mm, width 255 mm, height 197 mm.
