Abstract
This paper presents a design of a mesoband high power electromagnetic radiator using a coaxial switched
oscillator and a corona current generator. First, we present an FDTD simulation of the switched oscillator and compared
the obtained numerical results to the analytical equation derived by Baum. It is found that the analytical equation is able
to reproduce accurately the applied voltage to the antenna. We also describe a coaxial design of a corona current
generator that can be used as a source to the switched oscillator. The generator provides a natural DC isolation between
the radiat ..
