Miniaturized Thin Flexible Fractal-Slot-Based Artificial Magnetic Conductor for Radio Frequency Identification Applications

This paper designs a miniaturized flexible artificial magnetic conductor (AMC) based on a T-square fractal structure with slot operating at 920 MHz. The main advantage of the proposed AMC is the compact size, simplicity in design, and flexibility. This is achieved by optimization of the fractal-slot-based AMC structure on a thin polycarbonate substrate using computer simulation technology (CST) microwave studio simulator software. The results show that the proposed AMC is smaller in size compared to the conventional square-based AMC. In particular, unit cell size reduction of 22.4% is achieved, in which the unit cell size of the proposed AMC is 76 mm, which is only 23.3% of the operating wavelength. The proposed AMC can be applied in radio frequency identification (RFID) applications for performance enhancement.
