Abstract
The use of arrays of injection-locked voltage-controlled oscillators couple d to nearest neighbors has been proposed as a means of controlling the aper ture phase of one and two-dimensional (2-D) phased-array antennas, It has b een demonstrated both theoretically and experimentally that one may achieve linear distributions of phase across a linear array aperture by injection locking to an external oscillator the end oscillators of an arl ag of a mut ually injection-locked oscillators, These linear distributions cause steeri ng of the radiated beam, It is demonstrated theoretically here that one may achieve beamsteering in a similar manner in two dimensions by injecting ap propriately phased signals into the perimeter oscillators of a 2-D array, T he analysis is based on a continuum representation of the phase previously developed in the context of beamsteering via tuning of the perimeter oscill ators.
