Thus, by using a circular loop MCF element placed flat against an electric conductor, we can realize an extremely low profile monopole antenna. In contrast, electric current filaments produce a null field (i.e., they do not radiate)when placed flat against an electric conductor. Benefits: Small platforms, such as automobiles, now have an alternative to traditional HF/VHF/UHF monopole (blade) antennas which offer the potential of little or no visible signature. Return
