1. A method for providing an ultra-wide bandwidth monopole antenna having at least a 10:
- 1 frequency ratio, comprising the steps of;
providing a monocone in spaced adjacency to a ground plane;
sizing the height and the cone angle of the monocone to establish a low frequency cutoff;
sizing the apex base of the monocone, to establish the high frequency cutoff of the monocone antenna; and
feeding the antenna between the apex and ground plane.

Abstract
A low radar cross-section monocone antenna is provided with an ultra-wide bandwidth in the microwave region of the electromagnetic spectrum running from 1 gigahertz to 18 gigahertz by decreasing the low frequency cutoff through enlarging the overall dimensions of the cone while at the same time maintaining the base diameter of the apex of the cone to the initially-set dimension that establishes the high frequency cutoff of the antenna. The apex of this cone that serves as its feed point has a base diameter that results in the wide bandwidth, with the monocone antenna having a 5 dBi gain and omnidirectional coverage.
