  • Publication number: 20250158270
    Abstract: The disclosed wireless antenna may include a stratified architecture that electrically isolates an antenna radiating element from a ground plane. For example, the disclosed wireless antenna may be included in a wearable device such that the antenna radiating element is capacitively coupled with the bare skin of the wearer. A slot or cleared volume between the antenna radiating element and the ground plane causes electrical fields to close between the antenna radiating element—effectively enlarged by the bare skin of the wearer—and the ground plane. By clearly separating the antenna radiating element and the ground plane and coupling the antenna radiating element to conductive human tissue, the disclosed wireless antenna significantly improves performance at low frequencies such as LTD low bands. Various other methods, systems, and computer-readable media are also disclosed.
