摘要： The disclosed system may include an enclosure that is configured to house a printed circuit board (PCB). The PCB may have various internal electrical components mounted thereto. The system may also include a radiating component mounted to an opposite side of the PCB. Still further, the system may include a unified grounding structure that couples the PCB to the enclosure in multiple locations. As such, the radiating component may be grounded to the unified grounding structure at the multiple different locations. Various other methods, systems, and computer-readable media are also disclosed, including methods of manufacturing mobile electronic devices.

摘要： 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.
