In mobile communications in urban area, it is a significant problem that blind spots of in the narrow street are caused by high buildings. In this research, a new dual-antenna system is proposed, including a receiving and a reradiating antenna and feeding networks to realize a broad-angle beam control. An equivalent bistatic radar cross section (BRCS) is deduced to evaluate the antenna performance. The main advantage of this design over ordinary reflectarray antenna as a passive RF booster is its flexible beam control capabilities.
