Sažetak
Passive ultra-high frequency radio frequency identification systems (UHF RFID) have become essential components of contemporary logistics in various industries. They play a crucial role in facilitating critical operations such as asset tracking, inventory management and supply chain optimization. However, the effectiveness of these systems depends heavily on the design and efficiency of the antennas used. Therefore, this paper aims to improve the efficiency of a passive UHF RFID antenna by adopting a microstrip patch design. The proposed antenna comprises a rectangular patch with a looped slot printed on a slim single-layer dielectric substrate. To optimize performance, a comprehensive parametric study is carried out using the CST simulator with the objective of increasing the gain while reducing the overall antenna. As a result is a miniaturised slot antenna design with a total size of 87×85×0.9 mm3 and a gain of 4.14 dBi at 894.4 MHz frequency. This result will contribute to the advancement of passive UHF RFID antennas and create opportunities for enhanced detection reliability in relevant applications while simultaneously reducing system costs.
