Omron develops RFID antenna technology that boosts UHF tag reading performance. ...

... "OMRON Corporation, a global leader in automation, sensing and control technologies, announced that it has developed a new electronic control antenna technology. The technology is the first of its kind to be embedded in UHF-band RFID reader that can improve RFID tag reading performance. UHF offers significantly greater communications range than other frequency bands. As a result, the use of UHF RFID systems for full traceability of products has seen tremendous growth in the retail and logistics industries, mainly in the United States but also in other parts of the world. UHF tags, however, are subject to multipath interference, an inherent problem of electromagnetic signals, which can make an RFID tag unreadable even if it is within the range of the reader. To solve this problem, OMRON developed a new type of antenna technology that can electronically control the electromagnetic field emitted from the reader. By adopting this technology for UHF RFID systems, OMRON has succeeded in reducing reflections, thus minimizing the degradation of system performance due to multipath interference. While an electromagnetic wave from a conventional antenna propagates over a wide area as it travels in a given direction, OMRON's new antenna technology allows a wave with directivity to propagate in any specific direction, with the direction of the propagation controllable from the reader.
