Flexible Antenna Assembly for Well Logging Tools
First Claim
1. A well logging tool comprising:
- a tubular member;
at least one antenna assembly flexibly mounted on the tubular member, the antenna assembly including a flexible, non-conductive cylindrical core having an outer surface and an electrically conductive path positioned on the outer surface of the core, the electrically conductive path including an electromagnetic coil operable to transmit or receive electromagnetic energy; and
electrical circuitry electrically coupled to the at least one antenna assembly to provide electric current to or receive electric current from the electromagnetic coil.

Abstract
A disclosed example embodiment includes an antenna assembly for use in a well logging system. The antenna assembly includes a flexible, non-conductive cylindrical core having an outer surface and an electrically conductive path positioned on the outer surface of the core. The electrically conductive path forms an electromagnetic coil operable to transmit or receive electromagnetic energy. The electrically conductive path is formed on the core without winding a wire around the core using, for example, a removal process selected from the group consisting of milling, machining, etching and laser removal, an additive process selected from the group consisting of printing with conductive and dielectric inks and silk screening with conductive and dielectric epoxies or an integrated material deposition process such as a multi-material 3D printing process. The antenna assembly may be flexible mounted on a tubular member during assembly of a well logging tool.
