1. An antenna structure comprising a ground plane, one and only one planar feed element, one and only one planar parasitic element (230), one and only one feed conductor (203) and one and only one short-circuit conductor, the feed conductor being coupled to the feed element (240) and the short-circuit conductor being connected to the parasitic element, which, being larger in surface area than the planar feed element, is a main radiating element, and said feed element, which is not connected to the short-circuit conductor, being electromagnetically coupled to said parasitic element.
