Abstract

This paper introduces an active phased array antenna for mobile DBS service. The main idea for the antenna is to use twelve active array elements for cost effectiveness. For this purpose, the attractive hybrid tracking method with two-dimensional array structure is also used. The electronic beam scan coverage of this antenna is over 24 degrees wide in elevation, and 12 degrees in azimuth. The high-speed tracking capability of this antenna for fast moving vehicles gives other applications in satellite mobile multimedia services like mobile internet services by satellite hybrid link. Finally, this paper also introduces recent results for developing active phased array antennas for the high-speed data communications via satellite
