Abstract Picosecond pulses is much smaller compared to the membrane and nuclear membrane charging time of biological tissue (tens of nanoseconds and a few hundred nanoseconds), and it owns a rich spectrum of ultra wide band (almost from DC to GHz), which indicates high temporal resolution and spatial resolution. A wideband impulse radiation antenna (IRA) system was developed, which was composed of a cone structure with TEM coaxial feed and a prolate spheroidal reflector. It can focus the electromagnetic energy on a special target effectively. The E-field distributions of four kinds of models under different conditions were simulated, which could provide some optimal choices for the antenna design. The results shows that gain and field pattern of the antenna are stable, and voltage standing wave ratio is less than 2. At the same time, the pulse of focusing region maintains the input impulse characteristics, while the full width at high maximum of the electric field distribution generated in x-axis direction is less than 20mm, with y-axis and z axis 10mm.
