Convergence Acceleration Methods (CAMs) are presented for the fast analysis of wire antennas. Using this method, the convergence speed of wire kernel and its relative integrals expressed as exact series representations is greatly accelerated, and hence the computing time for the impedance matrix Z is greatly reduced. Finally, the validity and usefulness of the new method are illustrated with its application to moderately thick cylindrical wire antennas.
