On the Theory of Biconical Antennas

Abstract

The investigation contained in this paper gives a general treatment of the theory of biconical antennas based upon Smith's formulation of the problem. For the case of small-angle cones, an expression of the effective load admittance is obtained which is the same one that Schelkunoff derived based upon two rather ingenious methods, both of which, however, are not as rigorous as the present one. As an illustration of another application of the analysis, a treatment is given of the characteristics of biconical antennas where the space between the cones is filled with a dielectric other than air.
