Abstract: A system and method for controlling azimuth beamwidth in a wide band antenna array, the system including radiating element(s) disposed above a ground plane and parasitic element(s). The parasitic element(s) include a slot formed therein, the parasitic element(s) and slot(s) configured to control beamwidth across a specific frequency range. The parasitic element(s) and the slot(s) may be configured to control beamwidth across contiguous or non-contiguous frequency ranges.

Abstract: A system and method for providing a compact azimuth beamwidth in a wide band antenna. The system comprises a first radiating element disposed above a ground plane and one or more parasitic elements disposed proximate to and/or around the first radiating element. Each of the parasitic elements has a slot formed therein that is configured to control beamwidth across a specific frequency range. In one embodiment, the parasitic elements and the slots can be configured to control beamwidth across different frequency ranges. And in another embodiment, another parasitic element is disposed within the slots to control beamwidth across another frequency range.
