Collapsible impulse radiating antenna

1. Field of the Invention (Technical Field) A broadband collapsible impulse radiating antenna having a reflector and feed arms made from a flexible conductive material. An umbrella-like support mechanism is used to collapse and deploy reflector . The umbrella-like mechanism consists of a plurality of support ribs , a center support rod , center push rods , feed arm support rods , and push sleeve . Support ribs are attached to the reflector and are pivotally connected to a central hub . Push sleeve slides along center support rod causing the radial center push rods to provide a radial force to reflector and thereby deploy and collapse the antenna. Center can contains center support rod and an RF splitter that splits the input signal into two feed cables of equal length leading to the feed point . Optional expandable seams can be provided in the reflector and feed arms so that the surface curvature of the reflector can be adjusted.
