A method for the calculation of properties of wire antennas
Abstract
The properties of a symmetricallyfed dipole antenna are examined by methods of an integral equation and a modified transmission line approach. The kernel of the integral equation is explored, including a modification due to a hypothetical filamentary source along the antenna axis. An iterative form is developed for the antenna current, and transmission line equations are defined which are equivalent at the first iteration. A second order solution for the dipole antenna is formulated, along with an expression for the Hertzian vector and the input impedance. The deltafunction feed and the approximate kernel are found to be mathematically imcompatible. Further conclusions are drawn on the form of the quasistatic current near the origin, an explicit expression for the line reactance, and the use of a circuit equivalence to determine the amplitude for the iterative process.
