A logging tool includes a mandrel having a tool axis, a first loop antenna including first windings wrapped about the mandrel, a second loop antenna co-located with the first loop antenna and including second windings wrapped about the mandrel, and a shield secured to the mandrel. The first loop antenna is in a first orientation and the first windings are wrapped at a first angle. The second loop antenna is in a second orientation opposite the first orientation and the second windings are wrapped at a second angle. The shield includes first slots overlapping and along the first loop antenna and second slots overlapping and along the second loop antenna. The first slots define a first trace angle with respect to the tool axis and different from the first angle. The second slots defines a second trace angle with respect to the tool axis and different from the first angle.
