Fractal Geometries in Wireless Communication: A Focus on Sierpinski Carpet Fractal Antennas
Öz
This article explores the design and performance of a Sierpinski carpet fractal antenna aimed at achieving a resonant frequency of approximately 2.4 GHz, a critical band for wireless applications like Wi-Fi. The study emphasizes the advantages of fractal geometries in enhancing antenna miniaturization, bandwidth, and gain, making them suitable for modern communication systems. Using COMSOL Multiphysics, the antenna's electromagnetic characteristics were simulated and experimentally validated, focusing on reflection coefficients, radiation patterns, and impedance matching. The simulation revealed strong impedance matching at 2.432 GHz with an S11 reflection coefficient of about -30 dB, indicating minimal power loss. Experimental results closely align with simulations, confirming the design's narrowband operation and nearly spherical radiation pattern, which are suitable for applications such as RFID, Wi-Fi, and certain medical devices.
