Abstract

This technical report investigates the design and performance evaluation of compact dual-frequency Wi-Fi antennas tailored for integration into mobile devices. The antennas are designed to optimize size, efficiency, and performance over the 2.4 GHz and 5 GHz frequency bands that are essential for modern Wi-Fi standards. They are based on patch and meander line topologies. The important characteristics like return loss, VSWR, gain, radiation patterns, efficiency, and impedance bandwidth were carefully examined. Findings show that impedance matching was successful; gains were 2.1 dBi (2.4GHz) and 2.4 (5GHz) for the circular antenna and 3.8 dBi (2.4GHz) and 2.8 (5GHz) for the long antenna. The study emphasizes how the antennas' effective omnidirectional radiation patterns and small design can improve Wi-Fi connectivity in mobile devices. The outcomes validate the long antenna design's potential for more effective signal reception in radiosonde applications by showing a high gain enhancement.
