A phased array antenna system for INMARSAT mobile ground terminal
This paper presented a design of phased array antenna system for INMARSAT mobile ground terminal. Using GPS and electronic compass, antenna can scan the communication satellite automatically from 300 to 900 in elevation and 3600 coverage in azimuth through the DSP module. antenna gain is better than 14dB, diameter is less than 550mm, height is less than 110mm. In this paper, we put emphasis on the introduction of the design of the single-feed dual-band circular polarization micro-strip antenna element, the antenna system components and system performance. Measured results show that the antenna system be able to meet the maritime mobile satellite ground terminal applications.
