This study presents a novel UWB antenna featuring optimized radiation and incorporating a metamaterial-inspired design. The antenna utilizes a CPW-fed circular monopole paired with an 8×8 metasurface composed of low-profile metamaterial cells. Each cell has four star-shaped slots with identical arms, which contribute to the antenna's distinct electromagnetic characteristics. Both the antenna and metasurface are organized on an FR4. The results indicate that the design effectively spans from 3 to above 13 GHz, covering the 3.1-10.6 GHz UWB frequency spectra, offering strong frequency response, high radiation efficiency, and satisfactory gain. This antenna design is highly suitable for UWB applications, fulfilling the demanding specifications of contemporary wireless communication systems. This research work directly supports SDG 9 (Industry, Innovation and Infrastructure) by advancing the resilient and innovative communication infrastructure crucial for global connectivity.
