Abstract

A multiband antenna, including a ground plane, an open-ended radiating element offset from the ground plane and fed at a feed point, the open-ended radiating element radiating in a first frequency band and a conductive ground leg extending between the feed point and the ground plane, the conductive ground leg galvanically connecting the open ended-radiating element to the ground plane, the conductive ground leg radiating in a second frequency band and having an electrical length at least equal to about a quarter of a wavelength corresponding to the second frequency band.
