Abstract

Abstract

An ultrawide band paraboloidal reflector antenna for ultra-high repetition pulse has been developed. For improving radiant efficiency, the antenna adopted a new coplanar TEM feed structure, and the impedance and radiation characteristics were analyzed. Results show that the rEpmax value is about 18.3 kV and rEpp value is about 35.7 kV when the antenna is excited by a pulse of 180 ps risetime and 3 kV peak voltage. Compared with those antennas with TEM horns, this kind of antenna has the best radiating property.
- paraboloidal reflector antenna,
- ultrawide band,
- pulse,
- high radiant efficiency
