Claim Text:
1. An antenna comprising: a ground plane; and an array of helical antenna elements, each helical antenna element comprising a support structure and a conductor helically supported thereby, geometric centers of cross-sections of a helix formed by the conductor defining a respective axis of the helical antenna element, the axis extending from the ground plane in a direction substantially perpendicular thereto, the helical antenna element having a terminal end and having a base end mounted to the ground plane; wherein at least one helical antenna element of the array of helical antenna elements further comprises a conductive loading element at the terminal end of the array of helical antenna elements, the conductive loading element of the helical antenna element being connected to the conductor thereof and the center of the conductive loading element being laterally offset from the axis of the helical antenna element toward the centre of the array.
