Antenna system of ultrawideband borehole radar based on loaded electric dipoles

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
