Micro-strip Patch 2.4 GHz Wi-Fi Antenna Design For WLAN 4G- 5G Application

Abstract

In this study, an antenna with a frequency of 2.4 GHz has been designed that can be used in new generation wireless communication systems, which are in high demand with the development of technology. The designed antenna has Wi-Fi operating frequency range according to IEEE 802.11 standards. While choosing the antenna design, micro-strip antenna was preferred due to their geometry, lightness, low cost of production and compactness. While designing the antenna, the CST microwave studio program was deemed appropriate to be used and the necessary measurements were made. It has been deemed appropriate to use copper in the ground and patch parts of the antenna design. ROGERS 5880 (RT5880), for micro-strip circuit applications, was preferred as the substrate material. The dielectric coefficient of the selected material is 2.2. Its thickness is taken as 0.81 mm. As a result of the design, most of the intended goals were achieved. The gain of the designed antenna is measured as 2.73 dBi return loss value 30 dB and the bandwidth as in the 2.33-2.48 GHz range. These results are acceptable according to the standards. The 2.4 GHz antenna designed in this study can be used for Wi-Fi studies according to the experimental results.
