Competitive Advantages
- Improved reading range
- Reduced size compared to commercially available RFID tag antennas
- Low cost solution
Summary
Our researchers have developed a novel RFID tag antenna geometry for UHF Radio frequency identification systems using 3D printing. 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 the best 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 omni-directional beam pattern. Hence, this technology proves to be effective in terms of cost, size, weight and read distance.
