<p>An antenna has a ground plane (30) and a radiating element (15), and a shorting path (10, 110, 160, 170), coupling the ground plane (30) and the radiating element (15), the shorting path (10, 110, 160, 170) having an inductive element (10). The inductive element (10) can be a variable inductor. The antenna can have a short circuit path (160) across the inductive element (10), with a switch (170) to switch the short circuit path (160) in place of the inductive element (10).</p> |
