Abstract: The present invention refers to an antenna diversity system comprising at least a first antenna and a second antenna wherein the first antenna substantially behaves as an electric current source or as a magnetic current source, and the second antenna substantially behaves as an electric current source or as a magnetic current source and a corresponding wireless device. Further the invention relates to an SMT-type slot-antenna component comprising at least one conductive surface or sheet of metal in which the pattern of a slot is created, at least one contact terminal accessible from the exterior of said component to electrically connect the conductive surface included in the slot-antenna component with the ground plane of a circuit board such as a printed circuit board and a corresponding wireless device.

Abstract: The invention refers to an antenna comprising: a conducting trace (15, 20), said conducting trace (15, 20) defining a curve (1, 4, 5, 6, 6?, 6?, 8), said curve (1, 4, 5, 6, 6?, 6?, 8) including two or more feeding points (16a, 16b, 16c, 17, 18, 19), a portion of said curve (1, 4, 5, 6, 6?, 6?, 8) being shaped according a geometry selected from a group of geometries including a space-filling curve, a grid-dimension curve, a box-counting curve and a contour curve or the curve (1, 4, 5, 6, 6?, 6?, 8) or a portion of said curve having a shape of a multilevel structure. Further the invention refers to a related SMD component, an IC-package, a wireless device and a method for contacting an antenna.
