Abstract
A loop antenna assembly is provided that can include a loop antenna with one of more magnet wires encased in a non-magnetic flexible sheath and mounted to a transceiver block that is mountable to a tool body, where the loop antenna can at least partially encircle the tool body. The loop antenna can include a plurality of magnet wires each individually encased in the sheath, with a metal adaptor attached to each end. The magnet wire can be coated with thin insulation, thin enamel insulation, and/or a polymer film. A plane of the loop antenna can be perpendicular relative to the longitudinal axis or at an obtuse angle relative to the longitudinal axis. A non-magnetic locating ring positioned in the loop antenna assembly can secure the loop antenna of the assembly about the tool body.
