AI Technical Summary

Technical Problem

The increasing complexity and cost of radio frequency architectures in devices with smaller form factors, such as laptops and smartphones, due to the multiplication of radio front end circuitries, is exacerbated by the need for multiple radio transceivers to operate concurrently, particularly in millimeter wave technologies, which face challenges in integration, cost, and limited field-of-view.

Method used

An arc antenna array architecture with end-fire antennas disposed in an arc shape, eliminating the need for beamforming circuits like phase shifters or Butler matrices, allowing for high gain and wide spatial coverage without increasing complexity or cost, and supporting both communication and sensing applications.

Benefits of technology

The arc antenna array provides a cost-effective solution with enhanced spatial coverage, reduced complexity, and improved user experience by integrating easily onto contoured surfaces, supporting wide field-of-view applications like proximity sensing and gesture recognition.
