3D Tag with Improved Read Range for UHF RFID Applications

技术优势: Low cost solution, Improved reading range, Reduced volume and weight of tag compared to commercially available ID tag antennas.

详细技术说明: USF inventors used a 3D approach to design a novel tag antenna geometry for UHF Radio Frequency Identification systems. The antennas were compared to commercially available tags in size, weight, and read distance, showing a read range improvement of 136% (for a threshold power of 30 dBm) with respect to thebest tag tested. A reduction in length of 78 % with respect to a planar 2D model was also achieved. The radiation patterns were measured, showing an omnidirectional beam pattern.

*Abstract: Researchers at the University of South Florida have designed and developed a RFID tag antenna that is connected to a RFID chip to provide a good impedance match and the highest gain possible to improve read range.
