Claim 15:
16. A hybrid cavity mode antenna comprising:
an electrically-conductive chassis for a communication device, the electrically-conductive chassis having an electrically-conductive surface, a first electrically-conductive edge surface, and a second electrically-conductive edge surface;
a printed circuit board positioned within the electrically-conductive chassis;
a conductive wall defining at least a portion of a cavity, wherein the cavity is further defined by the printed circuit board, the electrically-conductive surface, the first electrically-conductive edge surface, and the second electrically-conductive edge surface of the electrically-conductive chassis, wherein the electrically-conductive surface is substantially parallel to a surface of the printed circuit board, and the conductive wall and the cavity are positioned bet wen the surface of the printed circuit board and the electrically-conductive surface; and
an electrically-fed antenna configured to radiate a first radiofrequency signal in a first frequency range, wherein the electrically-fed antenna is positioned within the cavity to drive the cavity to radiate a second radiofrequency signal in a second frequency range.
