(54) Multiple band antenna


(57) A dual band antenna includes a first conductor (4) in the form of a wire (7) wound in a helix, and a second conductor (6) in the form of a short stub inserted into the helix at a free end (10) thereof where the helix is adapted to operate substantially at a first operating frequency range and the second conductor electromagnetically couples with the first conductor for intrinsic operation at both first and second frequency ranges so that a particularly simple, reliable and easy to manufacture dual frequency band antenna is provided.
