Dual-Antenna System Composed of Patch Array and Planar Yagi Antenna for Elimination of Blindness in Cellular Mobile Communications

For a cellular mobile communication system in narrow streets of urban areas, blind spots caused by shadowing of high buildings are a signiflcant problem. In this research, a new dual- antenna system (DAS) is proposed, including a power transmission network, a receiving and a reradiating antenna to realize a broad- angle beam control. An equivalent bi-static radar cross section (BRCS) is deduced to present a theoretical explanation to the operating principles of the DAS. The main advantage of this design over ordinary re∞ectarray antenna as a passive RF booster is its ∞exible beam control capabilities. The simulated BRCS of the proposed DAS, composed
