Wide coverage area of UHF-band RFID system using a pattern reconfigurable antenna

Abstract A new type of a reader antenna for a UHF-band RFID system is proposed to cover a wider area. The proposed antenna consists of a circular polarized patch element, an omnidirectional electrical loop element, and a feeding network. By combining two antenna elements whose radiation patterns and half-power beamwidths (HPBW) are different from each other, the coverage area of the RFID system is increased. The experimental results show the proposed antenna has a HPBW of more than 120° and works well in the UHF band RFID system. © 2007 Wiley Periodicals, Inc.

RFID research and testing for packages of apparel, consumer goods and fresh produce in the retail distribution environment

Abstract Radio frequency identification (RFID) is a term used for any device that can be sensed at a distance by radio frequencies with few problems of obstruction. The origins of the term lie in the invention of tags that reflect or retransmit a radio-frequency signal. According to a recent article by Forrester Research, the minimal ,Slap and Ship' approach to RFID compliance will cost an individual company between $2 million and $20 million. Because retailers like Wal-Mart plan to share with their suppliers all the RFID-generated data points (from when a case/pallet enters their distribution centre until it leaves their stockroom), suppliers will eventually be able to use this data as a powerful forecasting tool. RFID is an enabling technology that can potentially facilitate a real-time, end-to-end supply chain visibility system. Suppliers who integrate full-scale RFID systems will realize efficiencies in time, material movement, inventory planning, shipping and warehousing both internally and externally. This paper provides a brief overview of the RFID technology, mandates by retailers and federal agencies, advances towards global standardization and typical consumer level RFID applications, and discusses RFID initiatives taken by some of the global leaders in apparel, consumer goods and fresh produce industries.
