The rapid expansion of internet networks in various sectors, such as education and e-commerce, relies heavily on Wireless Local Area Networks (WLAN). WLAN utilizes radio waves for data transmission, typically operating at the 2.4 GHz frequency. To enhance wireless communication efficiency, microstrip antennas offer a compact, lightweight, and cost-effective solution. This study focuses on the design and fabrication of a microstrip antenna featuring hexagonal patches arranged in a 4x4 array, specifically aimed at widening bandwidth for Wi-Fi applications. The research resulted in an external antenna device capable of increasing data transfer capacity while operating effectively at the 2.4 GHz frequency. Testing parameters demonstrated a return loss of -14.52 dB and a Voltage Standing Wave Ratio (VSWR) of 1.5, indicating efficient performance. Furthermore, the proposed 4x4 hexagonal array antenna achieved a bandwidth of 162 MHz. Implementation tests revealed a significant improvement in signal reception, with a power level of -37 dBm. This represents a substantial 12 dBm enhancement compared to the standard built-in antenna, which recorded a power level of -49 dBm. These results confirm that the design successfully provides superior signal quality for Wi-Fi networks.
