The highly integrated antenna design for the electric device is a trend to help
produce performance better appearance and style. Full metal surface treatment is
also a trend to deliver the better user experience in industry point of view. This
invention will introduce a cavity antenna design which will provide the full metal
environment scenario in laptop computer, and there will be an air channel RF
reflector to improve the placement possibility. This air channel RF reflect will break
through the limitation of the cavity antenna and provide the solution for the key
components which need air space such like speaker box or thermal fan to improve
the placement possibility.
