Abstract
An antenna including a substrate formed of a non-conductive material, a ground plane disposed on the substrate, a wideband element for coupling having one end connected to an edge of the ground plane and an elongate feed arm feeding the wideband element for coupling and having a maximum width of 1/100 of a predetermined wavelength, the predetermined wavelength being defined by formula (I) wherein λp is the predetermined wavelength, f is a lowest operating frequency of the wideband element for coupling, μ is a permeability of the substrate, εr is a relative bulk permittivity of the substrate, W is a width of a conductive trace disposed above the substrate and H is a thickness of the substrate, wherein formula (II).

1-16. (canceled)
A wireless communication device, comprising:
- a non-conductive substrate;
- a ground plane located on the non-conductive substrate;
- an element for coupling located in proximity to and offset from an edge of the ground plane with a gap therebetween;
- and
- an elongate feed arm located in proximity to and offset from the element for coupling and the edge of the ground plane along at least a portion of a length of the gap, the elongate feed arm being configured to feed at least one of the element for coupling and the ground plane.
