Simulation and Experiment of Phase Noise for Nonlinear Antenna Array

Nonlinear active antenna technique provides an efficient approach to generate stable high frequency signal source and finds its application in phase array. These techniques are Injection Locked oscillator(ILO), Phase Locked Loop(PLL) and Injection Locked Phase Locked Loop(ILPLL). Firstly, the noise performance and locking bandwidth of ILO , PLL and ILPLL are analyzed. Secondly, we completed the experiments of ILO , PLL and ILPLL. and draws the conclusion: ILPLL has superior noise performance compared with ILO and PLL.
