Abstract:
1. An apparatus comprising: an antenna element having a multi-band behavior and configured to operate in at least first and second non-overlapping frequency bands and comprising a plurality of geometric elements arranged to define empty spaces in the antenna element to provide at least first and second winding current paths through the antenna element, the at least first and second winding current paths circumventing the empty spaces and respectively corresponding to the at least first and second non-overlapping frequency bands to provide the antenna element with the multi-band behavior; and a ground plane, the antenna element being electrically coupled to the ground plane; wherein the antenna element provides a substantially similar impedance level and radiation pattern in the at least first and second non-overlapping frequency bands; wherein the geometric elements are arranged such that the antenna element does not comprise a group of single band antennas that respectively operate in the at least first and second non-overlapping frequency bands; and wherein the antenna element is not a fractal type antenna element.
