1. An antenna comprising:
- a monoconical antenna feed assembly having a base and an apex;
a ground plane located adjacent to said monoconical antenna feed assembly proximate the apex;
an antenna reflector coupled to said ground plane, said antenna reflector at least partially surrounding said monoconical antenna feed assembly;
whereinthe orientation of the reflector to the monoconical feed assembly is sloped at a first non-vertical angle relative to the ground plane,the orientation of the monoconical feed assembly is sloped at a second angle relative to the ground plane, andthe first non-vertical angle is different from the second angle.

Abstract
An antenna which includes a monoconical antenna feed assembly, where the feed assembly has a base and an apex, a ground plane adjacent to the monoconical antenna feed assembly near the apex, and an antenna reflector coupled to the ground plane, where the antenna reflector at least partially surrounds the monoconical antenna feed assembly. The monoconical feed point is used to drive a reflector antenna. The broadband characteristics of the monoconical image vertical antenna (typical ground plane geometry) are used as the feed point for the reflector to give modest amount of gain while maintaining larger than previously developed bandwidths.
