The present disclosure describes various antenna assemblies, each antenna coil being disposed about a tool body section in an antenna pathway. The antenna pathway passes through alternating grooves and lands. In each embodiment, at least one of the grooves is disposed in the tool body section at a non-axial direction relative to the longitudinal axis of the tool body section. The antenna coil can be an axial coil or a tilted coil. Additional grooves oriented at axial direction may be included. Also described are methods including acquiring a plurality of data pairs, each data pair comprising an induced signal at a receiver and a corresponding toolface angle using a tool including at least one antenna assembly disclosed, and a method to generate a measurement containing information about the directionality of the formation by calculating areas of an induced signal function approximated by the plurality of data pairs.
