In recent decades, the demand for high-quality communication has soared, particularly in the military and healthcare sectors. This study investigates modern anti-interference technologies for communication satellites by synthesizing data from reliable academic resources, including dissertations, journal papers, and periodicals. The research focuses on a comparative analysis of four primary anti-interference methods: frequency hopping, spread spectrum, encryption transmission, and adaptive antennas. Key performance aspects such as signal intensity, anti-interference capability, implementation cost, and complexity are evaluated. The findings indicate that adaptive antenna technology demonstrates superior performance, especially under extreme weather conditions, owing to its unique operational principles and robust anti-interference capabilities. This research concludes that adaptive antennas offer the most promising solution for ensuring stable and reliable satellite communication in challenging environments, and suggests that future advancements will continue to enhance the efficacy of these technologies.
