Band-Selective Phased Array Shading for Satellite Communications ID: 2014-008

This technology significantly enhances mobile satellite communications through innovative phased array shading techniques.

Technology Overview

This invention from Brigham Young University proposes a novel method to improve satellite communication transceivers. It focuses on using band-selective phased array shading to enhance the performance of mobile satellite terminals. By employing phased array antennas with electronic beam steering, the technology offers a lighter, less expensive alternative to traditional mechanically steered antennas. The core innovation lies in designing separate receive and transmit illumination shading across the phased array aperture, optimizing sensitivity and reducing interference.

Key Advantages

• Enhanced sensitivity and reduced interference in satellite communications
• Cost-effective and lighter alternative to mechanically steered antennas
• Electronic beam steering for dynamic and efficient communication
• Meets regulatory requirements with low sidelobe transmission
• Significant improvements in sidelobe reduction through innovative shading techniques

Problems Addressed

• Bulky and expensive mechanically steered antennas in mobile satellite terminals
• High sidelobe levels leading to interference and regulatory non-compliance
• Limited sensitivity and performance of traditional satellite communication systems

Market Applications

• Mobile satellite communication terminals
• Telecommunications infrastructure for remote and mobile applications
• Defense and aerospace satellite communication systems
• Commercial satellite broadcasting and data transmission services
