Claim Text:
1. Antenna structure-comprising: an active radiating structure-comprising at least an active radiating element; a passive radiating structure comprising at least a passive radiating element that can at least partially reflect and/or direct the electromagnetic radiation received and/or transmitted by the active radiating structure, and lacking an electrical pathway to the active radiating element; a ground plane structure comprising at least a ground plane element having a slot or cut-out, and lacking an electrical pathway to the active radiating element; at least a first circuitry to selectively electrically connect/disconnect said passive radiating element with/from said ground plane element; wherein said ground plane structure comprises regulating means for controlling the current distribution along said ground plane structure and, consequently, the radiation pattern of the antenna, when said antenna structure emits/receives an electromagnetic radiation; and wherein said regulating means comprise at least a second circuitry to selectively electrically connect/disconnect portions of said ground plane element, which are separated by said slot or cut-out.
