Abstract:

The modified dipole has its origin in the consideration of the general properties of a satellite antenna which bears great resemblance to a dipole modified to incorporate at the center a conducting volume which is used to radiate electromagnetic waves and to house a power supply and radio frequency generators, etc. 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.
