A Miniaturized HF/UHF Dual-Band RFID Tag Antenna

Research output: Chapter in Book/Report/Conference proceedingConference paperpeer-review


This paper presents a miniaturized HF/UHF dual-band antenna fed by a dual-interface RFID chip. The main goal of the antenna design is to achieve a compact, cost-effective, multi-purpose, and high performance RFID transponder. The proposed antenna utilizes the HF coil as a ground for a meandered monopole antenna operating at UHF band. An inductive network is adopted to achieve a conjugate matching between the antenna and the UHF chip interface. Measurements of a transponder prototype show a power sensitivity of −16.5 dBm, which corresponds to a realized antenna gain of approximately −1 dBi at 860 MHz.
