摘要

针对短波无线电传播环境下的多径衰落问题,提出了一种UHF/RFID频段多极化天线系统。移动车辆用超高频/射频识别(UHF/RFID)多极化天线系统是由多个微带天线组合通过射频组合器和分集单元连接而成。从测量结果可以看出,采用该多极化天线系统后,在视距/非视距短距离无线电波传播环境中出现的多径衰落明显减少。

A Multi-polarized Antenna System for Combating Multipath Fading in UHF/RFID Frequency Band in Moving Vehicles
This paper proposes a multi-polarized antenna system with UHF/RFID frequency band for combating multi-path fading in short-range radio propagation environments. The multi-polarized antenna system of the UHF/RFID for using moving vehicles is composed of multiple micro-strip antenna combinations connecting by the RF combiner and diversity unit. From the measurement results it can be seen that the multipath fading occurred in LOS (line-of-sight)/NLOS(non-line-of-sight) short-range radio wave propagation environment is markedly reduced by using the proposed multi-polarized antenna system.
