This paper presents a simple antenna system for land vehicle communication aimed at Engineering Test Satellite-VIII (ETS-VIII) applications. The developed antenna system which mounted into a vehicle is compact, light weight and simple satellite-tracking operation. Owing to low profile, a patch array antenna, which includes onboard-power divider and switching circuit for antenna feeding control, is...
Antenna system for land vehicle communications aimed at ETS-VIII applications was proposed. The proposed antenna system consists of an array antenna loaded with switching circuit onto which controlled by a developed program after receiving data input from gyro sensor of GPS unit. As a result, for an elevation angle El=48deg, three beams are electronically created in the azimuth direction with a minimum...
In this paper, we propose a configuration of antenna system for mobile ground terminal using GPS and gyroscope terminal unit as automatic-navigation system to track the ETS-VIII satellite. To miniaturize the antenna system we introduce an electronically tracking rather than mechanically by use of a developed control program. With this configuration the antenna system becomes light and low profile...
