【 摘 要 】

The design of an ultrawideband borehole radar antenna system based on loaded electric dipoles is presented. The antennas are designed to operate in a dielectric medium in the frequency range of 0.25-1 GHz. The results of calculations and measurements of antenna characteristics are presented. The results of sounding the objects when placing antennas in a medium with a relative permittivity of 4 are presented as well.
