Dual-Antenna System Using Series-fed Microstrip Antenna and Planar Yagi-Uda Antenna

摘要

Aplanardual-antenna system (DAS), composed of series-fed microstrip antenna and planar Yagi-Uda antenna, is proposed for eliminating blind spots in mobile communications system. The planar DAS is developed as a passive 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 blind spots and improving the propagation channel under the NLOS environment.
