TEM horn antenna for high energy pulse emission

In the paper a TEM horn antennna for 0.1 to 1 GHz band design is described. The antenna is appointed to emmitt subnanosecond high energy pulses of a high power short pulse generator, designed for testing of electronic devices resistance to high power electromagnetic pulse. The TEM horn uses tapered plates and their form was optimized using modelling and simulations in the CST Microwave Studio program. The designed horn parameters and antenna patterns are presented and discussed.
