  • Patent number: 12074386
    Abstract: This document describes methods and systems for an antenna system integrated with side-keys of an electronic device. The antenna system enables antenna integration in a metal frame using a metal support structure and fastener(s) to route antenna signals around side-key modules embedded in the frame without encountering or causing interference with the side-key modules. By using these techniques to integrate antennas on areas around the side-key modules, more antennas can be implemented on the electronic device, leading to improved capabilities supporting additional wireless standards and a better user experience in terms of improved communication quality.
