Patent ID: 8779999

Claim:
An apparatus comprising: an electrically conductive frame; and an L-shaped slot antenna formed, at least in part, by the electrically conductive frame and within a first plane of the conductive frame, wherein the L-shaped slot antenna includes a slot opening and is configured to provide at least a first frequency resonance and includes a feed point dividing the L-shaped slot antenna into an open-circuited portion and a short-circuited portion; a coupling element formed within a second plane of the conductive frame and separated from the conductive frame by a first insulating material, the coupling element being configured to be excited by an electrical signal via the feed point, the feed point being disposed proximate to the coupling element and the L-shaped slot antenna such that a first portion of the coupling element is proximate to the open-circuited portion and a second portion of the coupling element is proximate to the short-circuited portion; a coupling arm coupled with an end of the L-shaped slot antenna, the coupling arm being formed within a third plane of the conductive frame and separated from the conductive frame by a second insulating material, wherein the first plane, second plane, and third plane are different planes such that the L-shaped slot antenna, the coupling element, and the coupling arm are above or below each other.
