The Performance Enhancement of UHF RFID Reader in Multi-path Fading Environment Using Antenna Diversity

چکیده
Abstract: In wireless communication, the multi-path fading effect has big influence on the system performance. Especially, in passive UHF RFID system where tag is operated by the power supplied with the RF signal of the reader, the influence of multi-path fading increases. Therefore the communication performance changes drastically depending on the locations of tags and reader. In this paper, we propose a method to improve the performance of identification area and identifacation stability by using the antenna diversity. It decreases the shadow area and the bit error rate (BER) in situation of uniformly distributed tags.

Experimental Performance Evaluation of Dual Antenna Diversity Receivers for RFID Readers
Radio Frequency Identification (RFID) systems operating in the Ultra High Frequency (UHF) band, are exposed to fading. While state-of-the-art RFID systems employ multiple antennas, with random selection of a single receive path to obviate the performance losses, this paper proposes to employ antenna diversity by the combination of all paths applying maximal ratio combining. An experimental perf...

This paper investigates the problem of improving the identification performance of a UHF RFID system inside a room. We assume static reader, passive tags and availability of commodity antennas. A ray-tracing propagation model is developed that includes multipath in 3D space. It is found that careful selection of reader antenna placement and tilting must be performed to control destructive inter...
