Abstract

The boundary element procedure is developed for modelling the loaded dipole antenna embedded in a dissipative medium. Such approach provides a simple and efficient algorithm for the calculation of current distribution and input impedance. Numerical results are presented for current distribution and input impedance spectrum for a resistively loaded dipole antenna. 1 Introduction The input impedance of the electrically short wire antennas is strongly frequency dependent. On the other hand, the traveling wave antenna has input impedance which is essentially frequency independent. Some decades ago it was theoretically and experimentally shown that such a traveling wave antenna can be realized by a continuous resistive loading if the resistence per loa
