ABSTRACT:
The disclosed embodiments of the present invention include an antenna element having a generally low profile and providing a larger bandwidth. The disclosed embodiments include antenna elements having a top section with at least one cutout. Each cutout is provided with one or more tongues therein. The tongues extend from an edge of the cutout inward. The tongues may be coplanar with the top section or may be positioned between the top section and a bottom plate. Each tongue may be positioned separately to produce the desired antenna element characteristics.
