Abstract
A device for radio frequency communications includes an antenna cavity enclosed by at least four conductor walls, a gap between two perpendicular conductor walls at a first side of the antenna cavity, and a cavity extension extending at a direction perpendicular to the first side of the antenna cavity and aligned with the gap. The cavity extension extends from a second side of the antenna cavity opposite to the first side of the antenna cavity, and the cavity extension is closed at an end of the cavity extensions.

1-19. (canceled)
A device for radio frequency communications, the device comprising:
- an antenna cavity enclosed by at least four conductor walls;
- a gap between two perpendicular conductor walls at a first side of the antenna cavity;
- and
- a cavity extension extending at a direction perpendicular to the first side of the antenna cavity and aligned with the gap,
- wherein the cavity extension extends from a second side of the antenna cavity opposite to the first side of the antenna cavity, and
- wherein the cavity extension is closed at an end of the cavity extension.
A method for operating a device for radio frequency communications, the method comprising:
- detecting a folded state of the device;
- and
- switching off at least one of a plurality of antenna cavities of the device in response to detecting the folded state, and
- wherein the device comprises:
- an antenna cavity enclosed by at least four conductor walls;
- a gap between two perpendicular conductor walls at a first side of the antenna cavity;
- and
- a cavity extension extending at a direction perpendicular to the first side of the antenna cavity and aligned with the gap,
- wherein the cavity extension extends from a second side of the antenna cavity opposite to the first side of the antenna cavity, and
- wherein the cavity extension is closed at an end of the cavity extension.
A non-transitory computer-readable medium, having computer-executable instructions stored thereon, the computer-executable instructions, when executed by one or more processors, cause a device for radio frequency communications to:
- detect a folded state of the device;
- and
- switch off at least one of a plurality of antenna cavities of the device in response to detecting the folded state, and
- wherein the device comprises:
- an antenna cavity enclosed by at least four conductor walls;
- a gap between two perpendicular conductor walls at a first side of the antenna cavity;
- and
- a cavity extension extending at a direction perpendicular to the first side of the antenna cavity and aligned with the gap, wherein the cavity extension extends from a second side of the antenna cavity opposite to the first side of the antenna cavity, and
- wherein the cavity extension is closed at an end of the cavity extension.
The non-transitory computer-readable medium of claim 17, wherein the device further comprises a first frame and a second frame coupled by a folding mechanism, wherein the antenna cavity is located in proximity of the folding mechanism in the first frame, wherein the cavity extension extends away from the folding mechanism, and wherein the plurality of antenna cavities are located in proximity of the folding mechanism.
