Summary

• What is new: A novel beam-broadening algorithm for LEO SatComs that accounts for Earth’s curvature, maximizes PA efficiency, and minimizes interference.
• Why this is important: Ensuring quality of service in LEO Satellite communications by addressing signal path loss variation, power efficiency, and interference.
• What the research proposes: A new beam-broadening algorithm for uniform rectangular arrays that incorporates isoflux radiation patterns, constant modulus constraint, and out-of-beam radiation suppression.
• Results: The proposed method significantly suppresses out-of-beam radiation, meets design criteria, and offers at least four times greater channel capacity than traditional narrow-beam approaches.
