Abstract
An antenna assembly includes a tool mandrel having a tool axis; a first coil antenna including a first plurality of windings wrapped about the tool mandrel, wherein the first coil antenna is arranged in a first orientation and wherein portions of the first plurality of windings are wrapped about the tool mandrel at a first winding angle defined with respect to the tool axis; and a second coil antenna co-located with the first coil antenna and including a second plurality of windings wrapped about the tool mandrel, wherein the second coil antenna is arranged in a second orientation opposite the first orientation, wherein portions of the second plurality of windings are wrapped about the tool mandrel at a second winding angle defined with respect to the tool axis and wherein a difference between a loop area of the first coil antenna and a loop area of the second coil antenna is less than 25%.
