Measurement of the Parameters of Three-Element Nonresonant Dipoles with Two Reactive Elements

Resumo

A technique for the measurement of the parameters of three-dimensional nonresonant dipoles is proposed. The technique is based on measurements of the currents travelling through the dipoles and the phase shifts that occur as alternating voltages of two fixed frequencies are fed to the dipoles. An algorithm for performing measurements and processing results by means of the circle diagrams of currents at two near frequencies with iterative measurements of angles is considered. It is shown that the new technique may be successfully used to determine the parameters of three-element nonresonant dipoles with unique reactive component.
