Abstract

This paper describes the design and performance of a circularly polarized antenna for satellite communication applications. The antenna design includes a monopole patch antenna, split ring resonator, defective ground surface and a metallic reflector. The antenna is designed to operate in multiple frequency bands and to have high gain. The metallic reflector is used to enhance the antenna gain by reflecting the signal in the same phase as the transmitted signal, thereby strengthening the signal. The antenna resonates in 4.4 GHz and 7.6 GHz frequency bands, making it suitable for satellite communication applications. The paper presents both simulated and measured results of the antenna's performance, including return loss, gain, VSWR and polarization characteristics. The paper provides a detailed analysis of antenna's performance, demonstrating its suitability for satellite communication applications. The use of a metallic reflector, the split ring resonator and defective ground surface design results into antenna's high gain and multiband operation.
