UWB Dual-Polarized Antenna for HPEM Sources

A novel dual-polarized exponential tapered slot antenna for high power electromagnetic (HPEM) sources is designed and verified. This antipodal version of an ultra-wideband Vivaldi antenna offers compact sizes and sustains high input power of about 40 kV. Gains of about 8 dBi can be achieved. Both antenna planes are isolated with more than 20 dB.
