1. 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;
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 the first side of the antenna cavity, and wherein the cavity extension is open at an end of the cavity extension; and
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, and wherein the cavity extension extends away from the folding mechanism.
