1. An antenna comprising:
- (a) at least one main driven antenna element; and
(b) a plurality of parasitic antenna elements, where at least some of the parasitic antenna elements have coupling elements or devices associated with them for electrically coupling said at least some of the parasitic antenna elements to said one main driven antenna element, the coupling elements or devices being tunable to control a degree of coupling between adjacent antenna elements.

Abstract
An antenna having at least one main element and a plurality of parasitic elements. At least some of the elements have coupling elements or devices associated with them, the coupling elements or devices being tunable to thereby control the degree of coupling between adjacent elements. Controlling the degree of coupling allows a lobe associated with the antenna to be steered.

18. A method of steering an antenna comprising:
-
disposing at least one main antenna element and a plurality of parasitic antenna elements in an array adjacent a ground plane, where at least some of the antenna elements have coupling elements or devices associated with them; and
adjusting the coupling elements or devices to thereby control the degree of coupling between adjacent antenna elements in said array whereby the degree of coupling varies cyclically in radial directions away from said at least one main antenna element in said array. - View Dependent Claims (19, 20, 21, 22, 23)
