Characteristics of spiral top-loaded antenna (STLA) have been derived by the self-consistent field method, and a general design procedure has been systematized. The results of the analysis suggest that the STLA has desirable characteristics among very low frequency antennas because of its relatively small size, low feed voltage, and absence of tuning inductor.
