Modified Dipoles: I. Theoretical and Experimental Study

摘要

The object of the research is to pursue a theoretical and experimental exploration of the effects induced by the presence of the conducting volume on the antenna performance, i.e., input characteristics, current distribution along the surfaces of the entire radiating structure and radiation properties. In Volume I a mathematical model consisting of a perfectly conducting sphere from which project the ends of a thin biconical antenna is chosen to simulate the actual sphere-centered thin dipole. The conical antenna is driven at its junction with the sphere by a rotationally symmetric electric field maintained across the gap by a biconical transmission line excited by the TEM mode. (Author)
