Low profile antenna

摘要

A multi-band antenna (10) is provided that operates in at least two non-harmonically related frequency bands. The antenna includes a ground plane (12), a cone-shaped relatively high frequency antenna element (14) with a tip (18) of the high frequency antenna disposed adjacent to but electrically isolated from the ground plane with a base (20) of the cone-shaped antenna element extending away from the ground plane, and at least three relatively low frequency antenna elements (16) electrically connected to and extending between the base of the cone-shaped antenna element and the ground plane.
