Abstract :
The theory of a transmitting biconical antenna in a radially and continuously stratified medium is developed; its input impedance is computed and plotted vs. its length for various media and cone angles. The medium extends to infinity and is characterized by a complex dielectric factor \\xi=\\epsilon-i\\sigma /\\omega =\\epsilon_{0}f(r) , where r is the radial distance from the center of the antenna. For the "stratification function" the form f(r)= (kr+a)/(kr+b) is considered, where a and b are constant parameters, in general complex. The plots clearly exhibit all effects of dissipation and stratification expected on physical grounds and observed experimentally for dipole antennas.
