Abstract:
A multi-band antenna is provided that operates in non-harmonically related frequency bands. The antenna includes a primary antenna element for a first frequency band of the non-harmonically related bands, said primary antenna element extending perpendicularly from a ground plane, the primary antenna element electrically isolated from the ground plane, a plurality of secondary elements extending from the ground plane parallel to the primary antenna element and arranged in a circle around the primary antenna element, each of said plurality of secondary elements electrically isolated from the primary antenna element and ground plane and a plurality of antenna elements for a second frequency band of a higher relative frequency than the first frequency band, the plurality of high frequency antenna elements extending parallel to the primary and secondary antenna elements and disposed in a circle around the secondary antenna elements.
