Abstract
An apparatus configured to evaluate an earth formation that includes a tuned transmitter antenna and an untuned broadband receiver antenna. The transmitter antenna being configured to generate electromagnetic energy and the untuned broadband antenna configured to produce an output responsive to the generated electromagnetic energy. The untuned, broadband receiver antenna is configured reduce to reduce tool complexity, antenna coupling, and cross-talk between conductors to the antenna assemblies. The method includes using the apparatus in earth formation evaluation.
