Concurrent data processing from multi-port antenna of passive UHF RFID reader

In the present RFID sub-systems, the RFID reader scans data sequentially from individual antenna port by switching the multiplexer once at a time. When the number of antenna increases, the subsequent time interval of scanning data from any particular antenna may be sufficiently large, hence the probability of loosing any tag information passing through that antenna in any dynamic domain is very high. In this paper author proposes virtual concurrent data processing algorithm to scan the data parallelly and simultaneously from all the antenna at the single time quantum, thus minimizing the probability of loosing any tag information passing through any antenna in multi ported UHF RFID reader sub-system.
