Multiband antenna for mobile devices

摘要

The invention provides an antenna (1) for a mobile radio system, the antenna comprising two radiating conductive planes (2, 5) electrically connected together (at 4), a slot (3) in at least one of the planes, a feeder connection (6) disposed on one of the conductive planes, and a short circuit connection (7) connected to a ground (8) disposed on the same conductive plane as the feeder connection. The invention also provides a mobile radio device including an antenna according to the invention. The invention further provides a method of fabricating the above kind of antenna, including a step of cutting slots in a metal film and a step of bending the metal film to superpose two portions of the film.
