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