| Abstract: | In this paper, the local oscillator arrays were presented using the symmetry triangle coupled oscillator arrays, and its phase control principle was analyzed. It was deduced that the phase distributing was symmetrical when coupled-LO arrays was synchronized, and the phase step between coupled-LO array units only had relation with the boundary oscillators frequency. According this attribute the weight vector was derived, and the beamforming directional diagram was obtained. Thought, it was validated that the beamforming of antenna arrays using triangle coupled local oscillators was feasible. |
| Keywords: | nonlinear oscillator injection-locked coupled local oscillator triangle array beamforming |
