Input impedance calculation of vertical wire antennas above lossy ground using matrix pencil method

A method for evaluation of impedance and current distribution of vertical wire antennas above lossy ground is presented. Simulation is performed for several frequencies and the electrical parameter of soil. The results are compared with those of other methods showing the accuracy of our developed routine. In this paper we use Pocklington´s integral equation and we use the method of moment to solve it. Reshaping the integral equation is done for easier computation. To evaluate the produced Sommerfeld integral we use suitable path and employ a new method that is called matrix pencil method. Simple implementation by digital computer, fast and accurate simulation procedure and easy generalization for multilayer soil are the features of the proposed method..
