Abstract
A multi-band antenna is provided that operates in at least two non-harmonically related frequency bands. The antenna includes a ground plane, a cone-shaped relatively high frequency antenna element with a tip of the high frequency antenna disposed adjacent to but electrically isolated from the ground plane with a base of the cone-shaped antenna element extending away from the ground plane, and at least three relatively low frequency antenna elements electrically connected to and extending between the base of the cone-shaped antenna element and the ground plane.
