Abstract :
The problem of antennas of revolution with anisotropic surface impedance boundary conditions (IBC) is solved by the method of moments using the simplest basis function, pulse function, and Galerkin´s matching procedure. An electric field integral equation (EFIE) is used with different segmentations for the integral and the derivative regions. This method can also be applied to isotropic and conducting IBC. As an example, the electric current distribution and input admittance for a spherical antenna are given.
