Abstract
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 the 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. 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.

44. A wireless device comprising an antenna structure and a radio frequency (RF) module, the antenna structure comprising:
-
a ground plane comprising at least one slot; an antenna element comprising at least one feeding connection to electrically drive the antenna element and at least one ground connection; wherein the at least one feeding connection is coupled to the RF module; wherein the at least one slot features a short end in an inner part of the ground plane and a second end; wherein the at least one feeding connection and the at least one ground connection of the antenna element are placed respectively at two different sides of the at least one slot; wherein each of the at least one feeding connection and the at least one ground connection are closer to the short end than to the second end; and wherein the at least one feeding connection and the at least one ground connection electrically drive the at least one slot. - View Dependent Claims (45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63)
