An antenna comprising a lamina of conductive material, the antenna being operable in one or more resonant operational modes in which at least one portion of the antenna is associated with an relatively high electromagnetic field and in which at least one other portion of the antenna is associated with a relatively low or substantially no electromagnetic field. The lamina is folded on itself so that said at least one portion of the antenna lies on an obverse face of the antenna and said at least one other portion of the antenna lies on the reverse face of the antenna. In one embodiment, the antenna is a slot-loop antenna. In a second embodiment, the antenna acts as a quarter wave monopole.
