Abstract: Wellbore logging tools can include a coil antenna assembly that prevents breakage of a coil wire during downhole use under elevated pressure. The antenna assembly can include an insulator base used to help insulate the wires so elevated downhole pressures do not result in a short to a tool mandrel. The insulator base provides a recessed path for the in/out portions of the wire so manufacturing fixtures of the antenna assembly will not damage them.

Abstract: A single layer antenna path profile is provided. An antenna assembly for the single layer antenna profile includes a bobbin having a cylindrical body defining an outer radial surface, an inner radial surface, and a central axis. The antenna assembly also includes one or more channels defined in the outer radial surface. In some aspects, each channel is defined by a continuously curved inner surface having a constant radius. In some aspects, the inner surface extends more than 180 but less than 360 and thereby defines an opening in the body. The antenna assembly also includes a coil including a wire wrapped about the bobbin and received within the one or more channels. In some aspects, an arcuate portion of the wire extends through the opening such that a portion of the wire protrudes out of the channel.

Abstract: An antenna assembly includes a bobbin that provides a cylindrical body that defines an outer radial surface, an inner radial surface, and a central axis. One or more channels are defined on the outer radial surface, and each channel provides a first sidewall, a second sidewall opposite the first sidewall, a floor, and a pocket jointly defined by the first sidewall and the floor. A coil including one or more wires is wrapped about the bobbin and received within the one or more channels.
