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.
Claims22
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, wherein the second current path comprises first and second segments in the plane of the radiating structure and a bridging segment electrically connecting the first and the second segments, the bridging segment extending out of the plane of the radiating structure along an edge of the second current path;
- 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.

An antenna comprising:
- a slow wave ground conductor;
- a slow wave feed conductor;
- a planar conductive radiator conductively connected to the ground conductor and the feed conductor, the radiator comprising:
- a high band region providing a first current path having a length to create a resonant condition at a first frequency;
- and
- a low band region providing a second current path having a length to create a resonant condition at a second frequency, the second current path comprising first and second planar conductive segments and a bridging segment conductively connecting the first and the second segments, the bridging segment extending out of a plane of the first and the second conductive segments.
