Land Mobile Satellite (LMS) systems can exploit multiple-input-multiple-output (MIMO) techniques in order to achieve high transmission rates. This paper evaluates theoretically the capacity of single-input-multiple-output (SIMO) system utilizing uniform linear arrays at the receiver terminal for satellite applications. The theoretical study is performed at three different frequency bands. Sufficient capacities are achieved varying between 5 and 6.2 b/s/Hz at L and S bands being almost independent from the elevation angle. In Ku band the capacity is highly variable with the elevation angle, taking values between 2 and 5.9 b/s/Hz, whereas the maximum capacity values are observed in a blocked environment. At L and S bands the capacity is uncorrelated with distance for element spacing up to
