AN EXPERIMENTAL STUDY OF AN ELECTRICALLY THICK, TUBULAR, MONOPOLE ANTENNA DRIVEN BY A COAXIAL TRANSMISSION LINE

Abstract

Current distribution and input admittance of an electrically thick, tubular, monopole antenna driven by a coaxial transmission over a ground plane has been investigated and compared with theoretical results. When the circumference of the antenna is comparable to a free-space wavelength, this experiment verifies that the theoretical model of a tubular dipole antenna with a delta-function excitation only on the outside surface describes the experimental situation more properly than the conventional model of a delta- function excitation on both outside and inside surfaces of the antenna.
