Antenna system and method

摘要

A conical radiator coupled to an antenna patch disposed along a first end of the radiator, said patch disposed on an insulator. A ground plane is connected to the insulator and a radiomen is disposed opposite a second end of the radiator. The radiomen has a first region presenting a convex surface towards the radiator, and a second region presenting a concave surface towards the radiator. The first end of the conical radiator is the apex of the cone. A ground plane is included and a portion of the ground plane is a planar surface and another portion extends away from the planar portion towards the radiomen. Also disclosed is a method for forming a radiation pattern by shaping the radiomen to effectuate a predetermined radiation pattern using localized convex and concave surfaces positioned on the radiomen at different points in relation to the conical radiator.

1. A device for enhancing directivity in a desired radiation pattern including:
a ground plane; a radiator assembly capable of emitting electromagnetic radiation in the desired radiation pattern; a patch; and, a radome, positioned to cover the radiator assembly and connected to the ground plane,
wherein the radiomen includes a valley region approximately in the center of the radiomen, wherein the lowest point of the valley region is aligned with a vertex of the radiator assembly,wherein the radiomen further includes a first and second peak region separated by the valley region.
