Analysis of S-band Parabolic Antenna Performance for Microsatellite Communication Systems

This report constitutes of, as the title for this paper, Analysis of S-band Parabolic Antenna Performance for Microsatellite Communication Systems. The objective of the paper is to build an intelligent antenna in order to receive with less noise signal transmitted by Microsatellite. It will be a challenging project since the distance of satellite from antenna is quite far with a lot of noise can affect the transmission process. Microsatellite missions enable innovative scientific experiments using a low-cost platform but are limited by their small size and available solar power. This imposes strict power budgets on radio links. Enhancing ground station antenna systems can improve communication margins by increasing forward gain, forward-to-backward ratio, and directivity, ultimately boosting link performance with the satellite. The purpose of this paper was to analyze the performance evaluation of parabolic reflector with horn feed antenna for communication with frequency operating between 2 GHz and 3 GHz Amateur S-band. Parabolic antennas serve as effective high-gain solutions for microsatellite communication. The far-field radiation pattern produced by a parabolic reflector is influenced by the feed element's radiation pattern and the specific type and dimensions of the reflector employed. In this study, the antenna system is designed and simulated in the CST Microwave Studio to achieve specific requirements which are minimum power reflected back to the source and maximum gain with minimum front-to-back ratio, VSWR and radiation pattern for the antenna system.
