Abstract
An antenna, and method for forming the same, is provided that receives or transmits three (3) components of low frequency magnetic fields while having physical dimensions that can be easily housed inside a slim borehole tool. The antenna includes a permeable core and a plurality of sets of windings of conductive wire surrounding the permeable core, with each set of plurality of sets having a cross-sectional area associated therewith, with the cross-sectionals of the remaining sets. Typically, the cross-sectional area of each of the plurality of cross-sectional areas extends orthogonally to the cross-sectional areas of the remaining cross-sectional areas of the plurality of cross-sectional areas.
