Abstract: Metasurface antennas provide a compact and efficient solution for high-performance communication in small satellites, particularly within the X-band (8–12 GHz). This paper explores the design, analysis, and comparison of circular, linear, and dual-polarized metasurfaces, employing a single monopole feed for CubeSat applications. The proposed designs offer polarization diversity while maintaining a space-efficient structure suitable for satellite integration. HFSS simulations are conducted to evaluate key performance metrics, including Gain, S Parameter, and Radiation Pattern. The findings highlight the trade-offs among different polarization states in terms of signal integrity and environmental adaptability, offering valuable insights for optimizing metasurface antennas to enhance link reliability and polarization versatility in small satellite communications.
