Design and Interpretation of Microstrip Patch Antenna Operating at 2.4GHz for Wireless WI-FI Application

Abstract

With the renewed and changing technology in recent years, wireless communication has increased its importance in engineering, communication, transportation and almost every field. In this study, a Wi-Fi antenna with 2.4 GHz operating frequency, which is one of the leading studies of antenna technology, which can be used in wireless communication technology, has been designed. Wi-Fi antenna is very important for this technology, which has become indispensable for everyone today. To design the Wi-Fi antenna, the operating frequency specified in the IEEE 802.11 standards has been taken into account. While choosing the antenna model, micro-strip antenna was preferred due to its geometry, lightness, low production cost and compactness. While designing the antenna, CST Microwave Studio program was used and necessary measurements were made. While designing the antenna, FR-4 substrate with a dielectric coefficient of 4.3 and a thickness of 1.6 mm was used. Copper was used as the material for the ground and patch parts. As a result of the design, most of the intended goals were achieved. Graphs were analyzed from the CST microwave studio program. When the required S parameter value is examined; The antenna obtained as a result of this study operates in the 2.26 GHz-2.38 GHz band range, which is the targeted frequency of 2.4 GHz. The Wi-Fi antenna obtained in this study; return loss value is 25.90dB and gain value is 4.66 dBi. These results are acceptable according to the standards
