Abstract
The present invention provides a planar antenna having a first, outer planar conductive element and a second planar conductive element located in a hole in the outer element. At least 75% of the boundary between the hole and the first outer planar conductive element is a continuous concave smooth curve. The second planar conductive element is substantially coplanar with and surrounded by the first outer planar conductive element. At least 75% of the outer boundary of the second planar conductive element is a continuously convex smooth curve.
