Abstract
A communications device may include an RF device, and an antenna coupled to the RF device. The RF device may have a conductive ground plane, a conductive support rod carried by the conductive ground plane and extending outwardly therefrom, and a conductive body coupled to and surrounding the conductive support rod. The conductive body may have a helical slot to define a helical slot radiating antenna.
