Abstract Artificial magnetic conductor (AMC) is widely employed in microwave applications to reduce electromagnetic interference (EMI) and enhance the gain of the antennas. In this work, an AMC was designed, examined, and fabricated alongside a chipless Radio Frequency Identification (RFID) tag operating in an ultrawideband (UWB) frequency range for wireless applications. The tag and AMC are constructed with low-cost FR4 substrate, with 0.15 mm and 1.6 mm thicknesses, respectively. An AMC of 0.3 m × 0.3 m is employed for a 0.22 m × 0.22 m tag. The size of the AMC rings is to be optimized to ensure that the resonating frequencies of both structures nearly coincide. The proposed tag, equipped with an AMC, has been fabricated and subjected to experimental testing to confirm its performance. The results of the tests have shown that the tag can achieve read ranges exceeding 1.2 m. The presented work can be effectively utilized in wireless RFID applications to enhance gain, reading distance, and protection against electromagnetic interference within the resonant frequency range.
