The results of time-domain theoretical and experimental studies of ultra-wide band antennas with impulse excitation in radiating and receiving modes are presented. The antennas under consideration, like a monopole antenna, a dipole antenna and a horn-like antenna, are used widely for high-resolution videopulse subsurface (ground-penetrating) radars and should be operated near the border between two medias with different electrical properties.
