Assignee: ROSEMOUNT AEROSPACE INC.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 10:
11. A wireless communication device for use on an aircraft comprising:
a metallic chassis with a slot extending through a sidewall of the metallic chassis;
a memory, a processor, an input port, and an output port positioned within the metallic chassis, wherein the memory is electrically coupled to the processor, the input port, and the output port; and
a slot antenna coupled to an interior surface of the metallic chassis adjacent to and covering the slot of the metallic chassis, the slot antenna comprising:
a printed circuit board positioned adjacent to the metallic chassis 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;

wherein the resonator in the conductive layer and the slot in the metallic chassis are configured to produce a resonant frequency when a radio frequency current is provided to the printed circuit board, producing an electromagnetic wave at a frequency; and
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.
