Compact Antenna Design for RFID and IoT Applications

Radio Frequency Identification (RFID) as we know it is one of the promptly developing technologies in communication applications based on radio waves used in various sections related to security, tracking, ticketing, and more. This article proposes a small patch antenna design for RFID and wireless applications, using High Frequency Simulation Software (HFSS). The antenna has two slots etched on the radiator, and the ground plane has a rectangular slot to achieve resonance at 5.8 GHz and return loss at -26.93 dB with an impedance bandwidth of 300 MHz (5.64 - 5.94) GHz. The presented antenna was printed on an FR4 layer of 44 x 41mm

. Simulation and analysis of the antenna were performed by HFSS version 17.2. The simulation results show that the antenna provides good radiation efficiency and high gain, which makes the antenna suitable for RFID and wireless applications.
