Abstract
A monocone antenna includes a conical radiation element having a feed point at a vertex of the conical radiation element being connected to a feed transmission line and a capacitive ring radially outside of the conical radiation element and in proximity to the conical radiation element. The capacitive ring is connected to a ground plane of the monocone antenna. Optionally, a capacitive gap may be defined between the conical radiation element and the capacitive ring that is substantially filled with dielectric material.

A monocone antenna comprising:
- a conical radiation element having a feed point at an vertex of the conical radiation element being connected to a feed transmission line;
- and
- a capacitive ring radially outside of the conical radiation element and in proximity to the conical radiation element, the capacitive ring being connected to a ground plane of the monocone antenna.
A monocone antenna comprising:
- a substrate having a base and a top with a side wall between the base and the top, the substrate having a conical cavity open at the top and tapering inward toward the base, the conical cavity defined by an inner cavity wall;
- a conical radiation element on the inner cavity wall;
- and
- a capacitive ring on the exterior side wall radially outside of the conical radiation element and in proximity to the conical radiation element.
