Method to Increase Reader to Tag reading Distance in existing UHF Passive RFID System

摘要

This invention relates to an universal method to increase the tag reading distance by any existing UHF RFID reader system at 860MHz to 960MHz. The innovations are in following aspects: (1) Design of the new device (may called “Device-X”) which will be used with existing UHF RFID reader system to increase Passive Tag reading distance. (2) The mentioned device-X universally will support all the different passive UHF RFID class (ISO 18000-6A, ISO 18000-6B, ISO 18000-6C, EPC C1G1, EPC CIG2) readers to get enhanced read range. (3) Designing of the network architecture and said device-X parameter specifications which to be followed to get a very large region reading distance from the main RFID reader receiver antenna.
