In this manuscript, A compact geometrical configuration and simplified structure of a monopole antenna is given which is functional over an UWB frequency range (3.1GHz to 10.6GHz). The focus of the study is to design a compact and low-cost antenna that can provide an extended impedance bandwidth while maintaining stable and reliable radiation performance suitable for current wireless applications. The proposed design incorporates modifications to both the radiating patch and the ground plane to enhance impedance matching and improve overall radiation performance. Full-wave electromagnetic simulations are conducted to analyse these improvements, and a prototype is fabricated to validate the design experimentally. The measured results closely correspond with the simulated response, confirming wideband operation, consistent radiation patterns, and satisfactory gain levels required for UWB communication. The Proposed antenna design outperforms previous research due to its small size, wide bandwidth and high gain making it an excellent option for UWB systems. Because of its compact footprint, dependable wideband response, and simple fabrication process, the antenna is well suitable for portable and sensing-based UWB applications.
