EXPERIMENTAL VERIFICATION OF THE INPUT IMPEDANCE OF THE COAXIAL UNDERSEA ANTENNA

Abstract

An experiment was performed to check the expressions for the impedance of a coaxial type of antenna submerged in a conducting medium (sea water). The experiment was conducted at high frequencies in order to take advantage of frequency scaling. Details of the construction of the antenna along with methods and results of experimental measurements on the antenna are included. The experimental results check closely with the theoretical values obtained using expressions derived on the assumption that the antenna in a conducting medium is considered a transmission line with a lossy outer conductor.
