3D Tag with Improved Read Range for UHF RFID Applications
Technology Benefits
Low cost solution, Improved reading range, Reduced volume and weight of tag compared to commercially available ID tag antennas.
Detailed Technology Description
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.
