Abstract
Analysis of electromagnetics for an antenna analyzes a current on a conductor having a junction between a linear conductor and a planar conductor relying upon a moment method. A planar dipole segment 9 includes a planar monopole 91-2 in which the current flows in the same direction as the current flowing through part of a quadrangle 41-2-4 of a radial segment 41, and a planar monopole 91-1 in which the current flows in the same direction as the current flowing in a planar monopole 35-1 of a planar dipole segment 35. In the vicinity of the junction between the linear conductor and the planar conductor, currents are expressed that flow through the vicinity of the junction where three segments consisting of a radial segment and two planar dipole segments are overlapped one upon the other.
