Ultra-wideband high power photon triggered frequency independent radiator with equiangular spiral antenna

An ultra wideband RF radiator, comprising:

• an electrical energy storage device coupled to a source of electrical voltage, said device comprised of a dielectric medium consisting of first and second dielectric pieces each having an upper and lower surface, said upper and lower surfaces of each said dielectric piece having a metalized electrode resting thereon, said upper surface electrode of each said dielectric piece forming a spiral arm, said dielectric pieces separated by a predetermined gap distance and positioned with respect to each other such their spiral arms form a spiral antenna;
• and
• a photoconductive switch electrically connected to said spiral arms, said switch becoming conductive upon the application of a predetermined type of light energy such that the energy stored by said storage device discharges through a load, said discharge generating a time varying electromagnetic wave comprising a relatively high amplitude, narrow output pulse of nanosecond pulsewidth dimension.
