Design of a Half-Wave Dipole Antenna for Wi-Fi & WLAN System using ISM Band

Due to the low cost and high data transmission speed, the demand for wireless communication systems (WLAN, Wi-Fi) is increasing day by day. Nowadays, high-speed data transmission can be provided to a whole area or a building using WLAN and Wi-Fi systems. Since better performances and efficiency are expected for WLAN and Wi-Fi systems in the future, considering these issues, a Half-wave Dipole Antenna has been designed with an operating frequency of 2.45 GHz (ISM-Band). The antenna has been developed using the Copper (annealed) and the Perfect Electrical Conductor (PEC) material in the CST Studio Suite 2019 Software. After completing the simulation of the antenna, a Return Loss of -31.019 dB has been successfully achieved. A Gain of 2.026 dBi and a Directivity of 2.032 dBi was also achieved, respectively. The antenna's efficiency was determined as 99.70 %, which was calculated by using the value of Gain and Directivity. The other obtained performance parameters of the antenna are Surface Current, Bandwidth, etc. Considering all of the above performance parameters, the simulated Half-wave Dipole Antenna will be an ideal option for the WLAN and Wi-Fi systems.
