Use of active quenching for reduction of power dissipation in dipole antenna array

Reduction of power dissipation in dipoles upon incidence of plane waves by means of an oscillator coherent with the field of such a wave is extended from a single thin dipole to a finite periodic array of thin dipoles with an arbitrary direction of incident waves. The problem reduces to a system of Gallen integral equations for unknown currents and the solution is sought which minimizes the current norm. Calculations for an array with a period d = 1.8 lambda (lambda - wavelength) in both H-plane and E-plane, composed of 0.007 thick and 0.625 lambda long dipoles reveal that the quenching effectiveness factor depends only slightly on the angle of wave incidence. Varying the dipole dimensions reveals that it decreases fast with increasing dipole thickness and peaks to a maximum at some dipole length corresponding to resonance.
