Claim 0:
1. A slot antenna for use in a wireless communication device on an aircraft, the slot antenna comprising:
a printed circuit board coupled to a metallic chassis of the wireless communication device such that a conductive path extends between the printed circuit board and the metallic chassis and such that the metallic chassis forms a larger ground structure for the printed circuit board to amplify a communication signal and to transfer an electromagnetic wave at a specific frequency for communicating with other communication devices set to that specific frequency, the printed circuit board comprising:
a ground plane comprising a conductive layer and a resonator extending through the conductive layer of the ground plane;

an antenna positive feed terminal electrically coupled to a first side of the ground plane and extending across the resonator to a second side of the ground plane to an antenna negative feed terminal electrically coupled to the second side of the ground plane; and
a feed cable electrically coupled at a first end to the antenna positive feed terminal and the antenna negative feed terminal and electrically coupled at a second end to internal circuitry positioned within the metallic chassis;
wherein the slot antenna is positioned on the aircraft and the slot antenna is configured to send and receive communications signals from within the metallic chassis thereby protecting the slot antenna from operating conditions during flight of the aircraft.
