Abstract: The disclosed system may include an enclosure that is configured to house internal electrical components disposed on a printed circuit board (PCB). The system may also include a first antenna feed that is electrically connected to the PCB, to the enclosure, and to a radiating coupling arm configured for wireless communication in a first wireless communication band. The system may further include a second antenna feed that is electrically connected to the PCB and to an antenna configured for wireless communication in a second, different wireless communication band. The system may also include a first grounding leg that forms an electrical ground between the PCB and the enclosure, and a second, switchable grounding leg positioned away from the first grounding leg. This switchable grounding leg may provide a controllable electrical ground between the PCB and the enclosure. Various other methods and apparatuses are also disclosed.

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.
