Abstract
A broadband antenna system is disclosed. The antenna system relates to a cylindrical structure, wherein the feed region comprises segmented radiators with tapered feed points, distributed around the circumference of the structure, and a balun that is co-planar with the cylindrical structure. This allows a plurality of feed lines, cables, piping, or other structures to be run through the center of the antenna without interfering with the performance of the antenna system. Segmentation of the radiators permits the integration of a corporate feed network, suppresses overmoding, and permits operation without the need for a ground plane. The invention further relates to a stacked broadband antenna system wherein additional antenna elements or devices may be stacked collinearly on the antenna structure and operated via the plurality of feed lines or other structures. The overall system thus provides a wide range of transmitting, receiving, sensing and other capabilities over a virtually infinite bandwidth.
