Planar dual-antenna system for blind spots elimination in mobile communication system

A planar dual-antenna system (DAS), composed of series-fed microstrip antenna and planar Yagi-Uda antenna, is proposed for blind spots elimination in mobile communication system. The planar DAS is developed as a reflector in a non-line-of-sight (NLOS) environment. Broad-angle scattering and polarization transition can be realized. Equivalent bi-static radar cross section (BRCS) is used to demonstrate the effectiveness of the DAS in eliminating blindness and improving the propagation channel under the NLOS environment.
