US Patent 11777218 Antenna design with structurally integrated composite antenna components

This document describes techniques and apparatuses directed at antenna designs with structurally integrated composite antenna components. In aspects, an electronic device includes a mechanical frame having housing components configured to house electronic components. The electronic device further includes a composite antenna having at least one set of co-located antenna patches forming two resonance frequencies. The set of antenna patches includes an upper patch and a lower patch. The upper patch is formed integral to a housing component and operably connected to a feedline and an electrical ground. The lower patch is implemented in a flexible printed circuit board positioned proximately beneath the upper patch and operably connected to the upper patch through the feedline, as well as the electrical ground.
