Abstract-The design and analysis of a small circular patch antenna with a defective ground structure (DGS) for C and X-band applications are presented in this study. The antenna has a s11 39.2 dB magnitude when it resonates at 8.52 GHz. We used the EM modeling tool CST-STUDIO to optimize the radiation parameters and developed the antenna on a 14 x 14 mm2 FR-4 dielectric. We used this tool to run many simulations. The antenna was built with a peak gain of 7.4 dBi at 7 GHz for both C-band (4–8 GHz) and X-band (8–12 GHz) communication systems. Wideband characteristics and high gain of the antenna for wireless communications within the designated frequency bands, radar systems, and satellite communication. Comprehensive modeling and experimental results are provided to assess the effectiveness of the antenna and emphasize its suitability in modern high-frequency communication systems.
