Mathematical models of cylindrical spiral antenna
Физика волновых процессов и радиотехнические системы, 2013 In this article the cylindrical spiral antenna with a linear winding pitch that is placed over the perfectly conductive surface is considered. It was shown that with such statement this problem of currents distribution in a spiral is reduced to a solving
