Abstract
Disclosed are systems and methods which provide multi-band antenna elements using multiple radiating branches interconnected with a feed plate, thereby providing a multi-band antenna element having a single feed. Additionally or alternatively, a wide band antenna configuration is provided utilizing multiple radiating branches of a multi-band antenna element of the present invention. Embodiments utilize one or more reflectors, such as to provide directivity and/or radiation pattern shaping, including utilizing one or more radiating branches of a multi-band antenna element as a reflector for another one or more radiating branches of the multi-band antenna.
Claims80
An antenna element comprising:
- a first radiating branch associated with a first resonate frequency band;
- a second radiating branch associated with a second resonate frequency band;
- and
- a signal feed plate coupling said first radiating branch and said second radiating branch thereby providing a single signal feed with respect to said first and second radiating branches.
A method for providing an antenna element comprising:
- coupling a first radiating branch associated with a first resonate frequency band to a second radiating branch associated with a second resonate frequency band using a signal feed plate, said signal feed plate providing a single signal feed with respect to said first and second radiating branches.
A dipole antenna system comprising:
- a first dipole element associated with a first frequency band;
- a second dipole element associated with a second frequency band, wherein said second dipole element is oriented parallel to said first dipole element, and wherein said first frequency band is greater than said second frequency band;
- and
- a reflector providing reflection of both said first frequency band and said second frequency band, wherein said first dipole element is disposed between said second dipole element and said reflector.
