Abstract
An ultra wide band (UWB) antenna includes: (i) an array of antenna elements spaced from a central axis; and (ii) a network of lossy feedlines respectively communicatively coupled to the array of antenna elements. Each lossy feedline is periodically loaded with a resistance that is capacitively coupled to ground. Respective lengths of each lossy feedlines are selected to increase with an increase in distance from the central axis to achieve frequency independence of a radiated beamwidth from the UWB antenna.
