Abstract :
We present a Boundary Integral Method (BIM) for the computation of the current distribution in an antenna with negligible skin depth, the unknown quantities being the overall current intensity and the scaler magnetic potential on the boundary. After computing these quantities, the current density distribution can be deduced and the resistance as well as the inductance of the antenna evaluated. The results are compared with experimental values
