Abstract

Fractal antennas have gained significance in radio frequency applications owing to its compact design, better bandwidth, and low loss. This research article proposes a novel Spidron Fractal wide-slot antenna for 5.8 GHz Radio Frequency Identification (RFID) applications. An active RFID tag is designed to be in the size of 0.28 λr × 0.28 λr × 0.015 λr, (14.625 × 14.625 × 0.8 mm3) where λr is the resonant wavelength corresponds to the operating frequency, i.e. 5.8 GHz. The proposed slot antenna is printed on a 0.8 mm thick FR-4 substrate with relative permittivity of 4.4 and a loss tangent of 0.02. The proposed wide-slot antenna is excited by a 50 Ω microstrip line. The fractional impedance bandwidth is 15.52%, and the antenna gain achieved is 3.62 dBi, according to the results. The antenna's radiation performance is omnidirectional. These outcomes make the antenna suitable for RFID applications at 5.8 GHz.
