This research presents a novel antenna design tailored for satellite applications, incorporating a hybrid configuration comprising one Complementary Split Ring Resonator (CSRR) and nine Toothed Split Ring Resonators (TSRRs) on a defected grounded plane. The proposed antenna leverages metamaterials, characterized by unique properties like negative permeability and negative permittivity. The entire structure is implemented on an FR4 substrate with a height of 1.53 mm. The introduction of a slots enhances the antenna's versatility, enabling operation across multiple frequency bands i.e, 4.5 GHz, 5.05 GHz, and 5.55 GHz, resulting in notable improvements in gain, bandwidth, and return loss. Further refinement involves the truncation of antenna corners, resulting in circular polarization and enhanced impedance matching. Simulation tools such as CST, HFSS, and FEKO were employed to analyze and validate the proposed antenna design. Experimental testing in an anechoic chamber yielded a return l
