Abstract
The radiation characteristics for nearly-conical, semi-infinite, perfectly conducting bodies of revolution are calculated. The excitation is assumed to be performed by the given currents distributed in an axial-symmetric way at the top of the body and the wave-length of radiation emitted is assumed to exceed the radius of curvature of the top greatly. The problem of radiation from the top of conducting hyperboloid is solved exactly. For similar cases, not allowing the separation of variables, an approximate method based on separation of fields in quasi-static (corresponding to the proximity of the top) and wave-zones is formulated. It is shown that the total radiation loss for such nearly-conical bodies of revolution depends upon the frequency ω of the given currents as ωn. The powern is smaller than the valuen=4 corresponding to the Hertz's dipole and is determined uniquely by the cone's vertical angle.
