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.
