A broadband antenna, including a centrally-positioned radiating element, a dielectric support element generally surrounding the centrally-positioned element, and a linear radiating element, which extends along at least part of the length of the centrally-positioned element and a portion of which is wound over the support element around the centrally-positioned element. The centrally-positioned element preferably includes a linear metallic radiator, and the linear radiating element preferably includes a wire, such that the portion of the wire that is wound over the support element defines a helical radiator.
