Adjustable Helical Antenna

Abstract

The present invention provides a helical antenna with an adjustable height. When the antenna height is changed; the pitch and the number of turns changes without changing the overall diameter of the antenna. The helical antenna has a pitch that can be adjusted while preventing the antenna elements from buckling or otherwise deforming out of a helical arrangement. These pitch adjustments can change the operating characteristics of the antenna for different applications, environments, or other situations.
