Abstract
The radiation characteristics of an infinite cylindrical antenna, insulated from the surrounding warm plasma by a concentric cylindrical sheath of free space, are investigated for the case in which it is excited by means of a delta-function voltage source. The uncoupled electromagnetic (EM) and plasma (P) space waves are excited. The radiation pattern and normalized radiation resistance of the antenna for the EM and the P modes are studied as a function of 1) the frequency, 2) the radius of the antenna and 3) the thickness of the insulation. The effect of the insulating ion sheath is found to be of some significance only in the case of the P mode.
