Multi-loop antenna for high frequency RFID smart shelf application

This paper has presented a patent-pending multi-loop antenna for HF (13.56MHz) RFID smart shelf applications. The proposed antenna prototype has been able to generate magnetic field with uniform magnitude for a larger interrogation region. In addition, the low profile structure makes it very easy for implementation and not necessary for any modification to the shelf. Hence, the system installation cost has been reduced significantly. The patent-pending multi-loop antenna has been used for RFID smart shelves which are implemented in library for book management with achieved detection accuracy of 95-100%.
