Abstract
Mechanisms for induction-based resistivity measurements can be provided for use in geo-steering in a drilling operations environment. An antenna assembly can provide effective protection for antenna sections without hindering propagation of electromagnetic signals. The antenna assembly can include a bobbin disposed about a collar of a tool string; an antenna disposed on an outer surface of the bobbin; an outer adhesive layer covering the antenna and at least a portion of the bobbin; and a protective layer disposed against the outer adhesive layer; wherein the outer adhesive layer fills a space radially between the bobbin and the protective layer.
