摘要 This paper presents a novel electromagnetic metasurface-integrated antenna design that utilizes periodic structures to significantly enhance gain stability across the entire ultra-wideband (UWB) frequency range (3.1–10.6 GHz). Unlike conventional approaches that position metasurfaces as separate external elements, the proposed design directly integrates the metasurface into the antenna structure. This integration not only reduces spatial requirements but also improves overall compactness, making the antenna more practical for real-world implementation. The proposed antenna demonstrates consistent gain performance and a highly uniform broadside gain response throughout the full UWB spectrum. These advantages effectively address the persistent issue of gain fluctuation found in conventional UWB antennas, which is critical for maintaining stable communication performance. Furthermore, this work introduces a systematic design methodology that balances wideband impedance matching with enhanced radiation characteristics, advancing the application of metasurface technologies in antenna engineering. The proposed technique shows promising potential for future wireless communication systems and precision indoor positioning applications.
