The electric field at the surface of a cylindrical monopole

Abstract

Corona onset at the surface of an airborne antenna may limit radiated power and operating altitude. Corona may also be a source of severe electromagnetic interference to co-located receivers. Corona onset is a function of electric field strength and the maximum electric field produced by a linear antenna is usually at the antenna's surface. The electric fields at the surface of a cylindrical monopole are investigated both theoretically and by simulation. The partition theory of Schelkunoff and Friis is employed.
