Current Distributions on Transmitting and Receiving Antennas

A method for the direct measurement of the amplitude and phase of current and charge distribution along cylindrical antennas is presented for both transmission and reception. This method is applicable not only to the cylindrical antenna treated here but to many other antennas which may be used over a ground screen. The measured distribution on the transmitting antenna is continued into the coaxial line so that a complete picture of the system as a whole is obtained. The measured distribution on the receiving antenna is then shown to vary as a function of the terminating load as predicted by theory.
