Abstract：The dynamics model of weak coupling periodic antenna structure is established. Based on the dynamics model, vibration properties of the structure are studied. Active vibration control of the structure considering disorder is investigated by applying Linear Quadratic Regulator control method. Results of numerical examples show that small disorder of the structures can induce remarkable mode localization and ratio of the amplitude of perfect structure to that of disordered structure is about 30%. The disorder must be considered seriously while performing active vibration control of this kind of structure to avoid invalidation of vibration control system.
