Abstract :
In this paper, an improved model of oscillating AIA is proposed. Considering the frequency dependent model of patch antenna, we improve York´s nonlinear dynamic theory. Based on our improved model, the nonlinear phase-relationship of the coupling oscillating AIA has been primarily analyzed. It proved that dynamic characteristic of the four-element array performed better in this model. By changing the oscillating frequency of each active antenna, the beam scanning is realized without phase shifters.
