Abstract
An antenna, including a dielectric carrier having a bounding surface, and a conductive monopole resonant at a first frequency, the monopole having at least one conducting section mounted on the bounding surface. The antenna further includes a labyrinthine conductive coupling element mounted on the bounding surface so as to encompass the dielectric carrier. The coupling element is located with respect to the conductive monopole so as to transfer from the conductive monopole a second frequency lower than the first frequency.
