ABSTRACT:
An antenna is provided including first and second strip resonant elements, a dielectric and a metal cover. The first strip resonant element has an F-shaped area that lies in a first plane. The second strip resonant element has an L-shaped area that lies in a second plane that is parallel to the first plane. The second strip at least partially underlies the first strip. The dielectric is positioned between the first and second strips. A metal cover is provided. Part of the metal cover is positioned perpendicularly to the first and second strips so as to provide electromagnetic shielding for the first and second strips.
