Abstract
An antenna for radiating ultra wide bandwidth radio frequency pulses for in communications systems and sensors is disclosed in which a TEM horn is loaded by a resistively loaded parallel plate section and a shunt network connected to the parallel plate section in order to provide a low VSWR high efficiency antenna.
Claims10
An antenna for radiating UWB RF pulses, comprising:
- a transverse electromagnetic mode antenna having an input end and an output end;
- a resistively loaded parallel plate section connected to said output end of said transverse electromagnetic mode antenna;
- a shunt network connected between parallel plates of said resistively loaded parallel plate section;
- wherein said resistively loaded parallel plate section comprises two sections of parallel plates;
- and
- wherein each of said parallel sections of plates is comprised of a plurality of plates having varying widths.
