Abstract:

A new integral equation for the current distribution of an electrically thick tubular antenna which is driven by a voltage across a finite gap on an infinitely large ground plane is formulated. It is found that, in order to describe the experimental model of an antenna driven by a coaxial-line over a ground plane more correctly, an additional source term is required in the conventional integral equation of Hallens. This term can be expressed explicitly in terms of both the radius of the antenna and the dimension of the gap. A numerical solution of the integral equation has also been obtained by a so-called approximate product-integration technique and the results have been compared with the experimental data. Author
