Domestic mobile satellite communication system using 2.6/2.5 GHz band
Abstract
This paper describes domestic mobile satellite communication system concept using 2.6/2.5 GHz band. In this system a 1.85 m on-board satellite antenna covers the Japanese islands and the surrounding 200 nautical mile area. Two types of mobile terminals are considered, corresponding to voice and message services. For voice communication terminals, a 28 cm short backfire antenna is considered. For low bit rate (2.4 Kbps) message communication terminals, a 4.5 dB gain doughnut beam antenna without tracking is considered. Also, characteristics of the experimental mobile terminal antenna are described.
