The paper proposes a Ku-band ultra small aperture terminal (USAT) network offering various kinds of multi-media communications services. The USAT network proposed will accelerate the diffusion of the multimedia communications by enhancing the features of satellite communications such as multiple access, simultaneous distribution and wide service area. Furthermore, the USAT network is expected to be used in various kinds of service applications by a huge number of users owing to low-cost and easy installation of USAT terminal. The USAT antenna aperture size assumed in the paper is around 50-cm that is relatively smaller than the conventional VSAT antenna of around 1.2-m. As the key technologies for the realization of the USAT system, a low sidelobe simple antenna which meets ITU-R Recommendations, a carrier power spectrum density reduction technique for suppressing interference levels towards adjacent satellite systems, and an efficient multiple access method which can accommodate a huge number of USAT terminals with the higher throughput-delay time performance are proposed.
