(PSO) for wireless ultra-wideband (UWB) applications. The proposed fractal antenna design, featuring a central plus sign and an outer circular ring with eight smaller rings, enhances bandwidth for UWB response. The ground plane is modified with an etched curved slit to optimize antenna impedance. Utilizing PSO, we determine the fractal antenna’s dimensions with optimization goals of minimizing size while ensuring |S11| < −10 dB. Experimental data demonstrates strong performance across the 2.05 GHz–14.5 GHz frequency range,
covering diverse wireless standards like UWB from 3.1 up to 10.6 GHz, X-band from 8 up to 12.5 GHz, and lower band of Ku from 12.5 to 14.5 GHz. Consistent measured and simulated results validate our contribution’s applicability. Additionally, a time-domain analysis underscores the antenna’s adaptability to UWB applications, offering insights into its response to transient signals. |
