Abstract

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 gain more than 5 dBic and an axial ratio less than 3 dB. In addition, the antenna beam could be automatically switched with good results.
