ABSTRACT:
A resistivity tool for use in a wellbore is provided. The resistivity tool, in one embodiment, may include a longitudinal tool member, a first set of slots at a selected location in the longitudinal tool member and a conductor associated with the first set of slots to form a first antenna having a first orientation, and a second set of slots substantially at the selected location of the longitudinal tool member and a second conductor associated with the second set of slots to form a second antenna having a second orientation, thereby forming co-located antennas having different orientations.
