In the next few years the birth is expected of several ne wKa-band satellite communication system, based on a constellation of Geostationary Earth Orbit (GEO) satellites to provide a global coverage. A key part of these systems is the mobile satellite terminal, which has to satisfy several requirements, such as: ability to scan the beam, high gain, compakt design and lowcost. A survey of the recent advances in antenna technology for mobile satellite terminals is presented in this paper. Among those solutions, a new active antena is presented, consisting of a slotted waveguide array electronically scanning in the elevation plane. This solution combines the high perfomance of an active phased array with the low cost of a passive fixed beam slotted waveguid array.
