DEVICE AND METHOD FOR CONTROLLING AZIMUTH BEAMWIDTH ACROSS A WIDE FREQUENCY RANGE

摘要

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.
