Claim 0:
1. A communication device comprising:
a metal chassis;
a printed circuit board positioned within the metal chassis; and
a hybrid cavity mode antenna, the hybrid cavity mode antenna including:
a conductive wall defining at least a portion of a cavity, wherein the cavity is further defined by one or more surfaces of the metal chassis and the printed circuit board, wherein the metal chassis includes a metal surface that is substantially parallel to a surface of the printed circuit board, and the conductive wall and the cavity are positioned between the surface of the printed circuit board and the metal surface, and
an electrically-fed antenna configured to radiate a first radiofrequency signal in a first frequency range, wherein the electrically-fed antenna is electrically driven from the printed circuit board of the communication device, the electrically-fed antenna being positioned within the cavity to drive the cavity to radiate a second radiofrequency signal in a second frequency range.
