Abstract
An antenna assembly includes a portion of the metal computing device case as a primary radiating structure. The metal computing device case includes a back face and one or more side faces bounding the back face. The metal computing device case further includes a radiating structure having an aperture formed in the back face from which a notch extends from the aperture cutting through the back face and through at least one side face of the metal computing device case. A conductive feed structure is connected to a radio. The conductive feed structure is positioned proximal to the radiating structure of the metal computing device case and is configured to excite the radiating structure at one or more resonance frequencies.
