An article comprising:
- a conductive body;
- a magnetic diverter positioned on an outer surface of the conductive body, the magnetic diverter covering a substantial portion of the outer surface of the conductive body;
- and
- a communication device;
- wherein the communication device comprises at least one of (i) an RFID tag, (ii) a resonant RF circuit, and (iii) a smart sensor;
- wherein the communication device comprises a first antenna and a second antenna, the second antenna being in electrical communication with a phase shifting circuit,
- wherein the phase shifting circuit shifts the voltage of the second antenna by about 90 degrees,
- wherein the first antenna has a first portion and a second portion, and
- wherein the first portion is positioned on an outer surface of the diverter and encloses the article in a sweep of about 180 degrees and wherein the second portion is longitudinally offset from the first portion and encloses the article in a sweep of about 180 degrees which is opposite the sweep of the first portion.
