Automated design of an HF RFID loop antenna based on parametric geometry modification

In this paper, we take an innovative approach to the design of RFID loop antennas. As we want to increase the reliability of HF RFID systems, we need to step away from the traditional circular antenna shape. Adapting the shape of the antenna to its environment will improve the reliability of the HF RFID systems with a single loop antenna. We compare various shapes to serve as a reader antenna in a metallic tunnel. The optimized loop antennas are created by an antenna design tool which combines MATLAB® and CST EM Studio®. One of the optimized loop antennas is selected to serve in a practical case. Measurements were performed on this practical case with some promising results. © 2014 IEEE.
