ABSTRACT:
This invention refers to an antenna structure for a wireless device comprising a ground plane and an antenna element, wherein the ground plane has a slot with at least a short end, an open end and a length substantially close to a quarter wavelength. The feeding and ground connections of the antenna structure are placed at the two different sides of said slot and the distance of at least one of them to the short end of the slot is equal or smaller than an eighth of the wavelength. The invention further refers to an antenna structure for a wireless device comprising a ground plane and an antenna element, wherein the ground plane has a slot with at least two short ends, and a length substantially close to half wavelength. The feeding and ground connections of the antenna structure are placed at the two different sides of said slot and the distance of at least one of them to a short end of the slot is equal or smaller than a quarter of the wavelength. Further the invention refers to a corresponding wireless device, a corresponding mobile phone and to a method for integrating such an antenna structure within a wireless device.
