摘要: The present invention relates to antennas and in particular a multi-resonant antenna. addresses the requirement for dual frequency operable two distinct bands. In accordance with first aspect of invention, there is provided antenna comprising second conductive elements which extend relative ground plane; wherein structure are adapted couple between themselves provide variable phase velocity surface currents radio signals. A method operation also disclosed.
