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.
