Abstract
An apparatus includes a multi-band antenna element that operates in at least three frequency bands and includes geometric elements arranged to define empty spaces in the antenna element to provide at least three winding current paths through the antenna element which circumvent the empty spaces, the at least three winding current paths respectively corresponding to the at least three frequency bands, wherein each of two or more of the geometric elements is traversed by more than one of the at least three respective winding current paths. The antenna element provides a substantially similar impedance level and radiation pattern in the at least three frequency bands. The geometric elements are arranged such that the antenna element does not comprise substantially non-overlapping portions that serve as respective single band antennas, and a geometry of the antenna element is not substantially self-repeating.
