Abstract

Objectives: This study aims to design and analyze a novel compact antenna suitable for WLAN applications operating at 5.2 GHz. The primary objective is to enhance the antenna’s bandwidth to meet the increasing demands of wireless communication technologies. Methods: The antenna design utilizes a compact form factor with dimensions of (12.5 x 16.9 x 1.64) mm3 and employs FR4 as the chosen substrate material. The simulation is conducted using HFSS software, a reliable tool for antenna analysis and optimization. Findings: To achieve improved performance, the antenna incorporates dual L-shaped slots into its patch structure. These L slots are comprised of vertical and horizontal components, with sizes of (8 x 1.5) mm2 and (2 x 2) mm2 respectively. By subtracting these L-shaped slots from the antenna patch, both gain and bandwidth are significantly enhanced. The practical construction of the antenna validates the simulation results, showcasing a bandwidth increase of 480 MHz centered around a resonant frequency of 5.30 GHz. Novelty: In response to the burgeoning demand for expanded bandwidth in contemporary wireless applications, this study introduces a novel antenna design. The integration of dual L-shaped slots, along with the strategic subtractive optimization approach, presents a fresh and effective solution for fulfilling the requirements of advanced WLAN technologies.
