Paper Abstract

Recent results are reported that improve the prompt radiated response from reflector and lens impulse radiating antennas (IRAs) by improved control of the aperture fields of the TEM mode distribution. Both reflector and lens IRAs benefit from trimming the aperture to eliminate portions where the vertical component of the electric field is oriented in the wrong direction. Reflector IRAs can further benefit from reorientation of the TEM feed arm angles as well as the relative size of the feed arms to the maximum aperture radius. Significant improvements over 45-degree feed arms can be realized by making 200-Ohm reflector IRAs with feed arms at 30 degrees from the vertical with the circle of symmetry slightly inside the aperture outer boundary and small amounts of aperture trimming.
