Abstract
An edge fed patch antenna is designed to operate in the Wi-Fi band of 5.2 GHz. For improving the band width and for achieving multiband operation, a Koch fractal DGS structure was incorporated into the ground plane. On introduction of fractal DGS, the antenna exhibits dual-band operation at 3.9 and 6.8 GHz. In order to obtain the originally designed frequency of 5.2 GHz, the antenna structure was optimized using Particle Swarm Optimization (PSO). The optimized antenna resonates at 5.2 GHz and also at 3.5 GHz, which is the proposed frequency for 5G operations. So our optimized antenna exhibits dual-band operation and is suitable for Wi-Fi and 5G applications. Also, it provides good gain in the operating frequency bands. This novel antenna design approach provides dual-band operation with enhanced bandwidth in compact size. The antenna structure was simulated and its performance parameters evaluated using OpenEMS.
