Abstract

In order to make the scanned radiation beam range wider, phased array operation of an active antenna radiating the second harmonic is studied. By numerical analysis of a coupled oscillator system modeling the active antenna array, it is shown that the variation of the phase difference of the second harmonic component between the oscillators reaches 2π when the oscillators are coupled only by the fundamental components. This value is twice that yielding the fundamental component. Through experiments using two- and four-element arrays, the results of the analysis are confirmed. The radiation beam of the second harmonic is successfully scanned in a wider range than that for the fundamental component.
