A body structure has an inner region shape that defines a cavity within the body structure. The invention includes a novel antenna comprising a first dielectric substrate having opposite first and second surfaces, a patch of conducting material disposed on the first surface, a ground plane of conducting material disposed on the second surface, and at least three input ports, each input coupled to the patch at a feed point. The user can select between \u201cprint\u201d and \u201csend\u201d as an alternative process for the undisplayable data. The system is modular so that the capacity can be expanded as required.
