Development of H-shaped fractal slot antenna for WLAN/WiMAX and sub-6 GHz 5G wireless applications

Abstract Sub-6 GHz frequency band offers enhanced channel capacity and adequate bandwidth for wireless 5G automotive applications. Such applications demand user equipment antenna terminal with multiple resonating frequencies with acceptable gain to ensure the reasonable data rate for effective communications. To meet these specific requirements a H-Shaped fractal slot patch antenna with shorting metal strip is presented for WLAN/WiMAX and sub-6 GHz 5G wireless applications. Further, Whale Optimization Algorithm (WOA) is used to find the optimum position for a shorting strip placed between the fractal slot patch and ground. The proposed antenna has been evaluated with a set of representative numerical simulations have been done as per design specifications. The projected antenna resonates at S-band and C-band frequencies aroundn41 band, n46 band and n78 band. The antenna has a peak gain of 13.2 dB in the resonating range. The measured result confirms the accuracy of antenna design and results are quite promising.
