RFID performance in high-voltage corona

This paper presents a general analysis of radio frequency identification (RFID) performance when surrounded by a corona plasma resulting from placement on a high-voltage source. It is found that a plasma layer can detune a planar antenna by 4%. Results also indicate that lower frequencies in the microwave bands may be used to minimize attenuation effects, and planar antennas may minimize corona plasma formation due to the low potential gradients on their flat surface.
