Abstract
This manuscript presents the design, fabrication, and performance evaluation of microstrip patch antennas tailored for Wireless Local Area Network (WLAN) applications, specifically IEEE 802.11b/g/n standards. Emphasis is placed on techniques prevalent up to 2018, including substrate selection, feed methods, and optimization of return loss and radiation patterns. A prototype antenna operating at 2.4 GHz is fabricated using FR4 substrate. Simulated and measured results demonstrate a bandwidth of 100 MHz, a gain of 6.2 dBi, and efficiency over 75%. The research underscores fabrication tolerances and suggests avenues for enhancing gain via array configurations.
