Abstract

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