Abstract
An antenna system includes a metal housing including a first edge and a second edge that meet at a corner and a slot located proximate the second edge that extends from the first edge parallel to the second edge defining a strip and an antenna located behind and in close proximity to the strip. The antenna is coupled to the strip. A parasitic element is located proximate the antenna and the strip includes a ground coupling that crosses the slot in spaced relation thereto. The parasitic element assists in establishing second and third higher frequency modes of the antenna system.
Claims26
An electronic device comprising an antenna system including:
- a metal housing wall including a slot;
- an coupling structure located proximate said metal housing wall and coupled to said metal housing wall proximate said slot.
The electronic device according 11 to claim wherein said parasitic element includes a grounding tab that is positioned in spaced relation from said slot between said open end of said slot and said closed end of said slot.
A wireless communication device comprising:
- an antenna system including:
- a metal part including:
- a first edge and a second edge that meet at a corner, a slot formed in said metal part extending from said first edge, proximate to said second edge thereby defining a strip bounded on three sides by said slot, said first edge and said second edge;
- a coupling structure coupled to said strip;
- a parasitic element disposed proximate said coupling structure substantially overlying said strip in spaced relation to said strip;
- a grounding conductor extending from said parasitic element across said slot and galvanically coupled to a portion of said metal part located across said slot from said strip.
