EXPERIMENTAL STUDY OF ELECTRICALLY THICK MONOPOLE ANTENNAS. I. EQUIPMENT, ADMITTANCES AND IMPEDANCES,
Abstract
The purpose of this research was to investigate the behavior of electrically thick cylindrical antennas by obtaining experimental data on a physics counterpart of a theoretical dipole antenna model. The experimental apparatus, consisting of a monopole antenna driven over an image place by means of a coaxial line, was designed to allow for the measurement of antenna characteristics over a 0.1<or=ka<or= 1.0 thickness range, where a is the antenna radius and k = 2 pi/wavelength is the propagation constant. This is a thickness range for which all higher order coaxial modes are still below cutoff but, on the other hand, ka values are large enough that they are out the range of validity of linear antenna theory.
