1. An antenna comprising:
- a radiating conductive structure, further comprising;
a first current path for providing a resonant condition at a first resonant frequency;
a second current path for providing a resonant condition at a second resonant frequency;
a common feed conductor for the first and the second current paths, wherein the feed conductor is connected to the radiating structure; and
a common ground conductor for the first and the second current paths, wherein the ground conductor is connected to the radiating structure.

Abstract
An antenna for transmitting and receiving radio frequency energy. The antenna comprises a conductive radiator comprising a first and a second conductive region for providing a first and a second current path length. A feed conductor and a ground conductor operate as meanderline (or slow wave) elements to provide an electrical length longer than a physical length.
