The possibility of integrating single-wall carbon nanotubes (SWCNT) in RF receivers was investigated in this work. We have approached this by two methods; replacing copper in copper coils by SWCNT and coating copper coils with sufficient thickness layer of SWCNT. Replacing copper with Single-wall carbon nanotubes shows promising results with some challenges. These hurdles are; high DC resistance and low impedance values. Using different CNT grades might help to overcome these challenges. Because of the high DC resistance of the CNT layer, coating copper with SWCNT layer did not affect the coil performance in terms of resistance, impedance, or quality factor.
