Abstract

A 4-element multibeam microstrip smart antenna system at 1.96 GHz is presented. It can be used in communications system such as the base station antenna of land mobile radio system. Test results showed that this microstrip smart antenna system is capable of automatically adjusting its radiation pattern direction, tracking the stronger receiving signal and rejecting the relatively weak co-channel interference by mean of internal feedback control while the system is in operation. This 4-element multibeam microstrip smart antenna system has significant improvements in not only increasing the spectral efficiency, capacity, and extending the range of coverage but also small size, light weight and lower cost.
