Abstract
A well-logging tool for a geological formation includes a housing to be positioned in a borehole and an antenna assembly carried by the housing. The antenna assembly includes an antenna housing having a recess therein. A dielectric material layer comprises a basalt fiber composite and is within the recess. At least one antenna coil is supported by the dielectric material layer. An electrical connector is coupled to the at least one antenna coil. Resistivity processing circuitry is coupled to the electrical connector to determine an electrical resistivity of the geological formation based on the at least one antenna coil.
