AI Technical Summary

Technical Problem

Current wireless communication systems face challenges in achieving high spectral efficiency, reduced latency, and enhanced signaling efficiency, particularly in vehicle-based communications where RF signals often face interference and attenuation due to the vehicle's structure.

Method used

The integration of an array of optically transparent and electrically conductive lens elements within a glass assembly, such as a vehicle windshield, which imparts a plurality of phase shifts to incident radio-frequency (RF) waves, enabling improved RF signal transfer and manipulation.

Benefits of technology

This solution enhances RF signal transfer by providing high-gain, directional radiation and impedance matching, thereby improving antenna performance, increasing signal strength, and reducing interference, particularly in vehicle-based communication systems.
