Based on previous theoretical and experimental research progress of reconfigurable antennas as well as Metamaterial, reconfigurable lens antennas which rely on control metamaterial are further explored. The following contents are to be studied deeply: 1)the research of control Metamaterial along with the analysis of its electromagnetic properties and the influence of control signals on Metamaterial properties and their range. 2)the study of the most situable calculations of electric field distributing over the aperture that satisfy far field radiation properties on the basis of iterative algorithm of coupled mode theory. 3) obtain the design algorithm after researching propagation features of electromagnetic waves in non-uniform medium, and study the steering range of the lens antenna beam. 4)the research of dynamic reconfiguration characteristics of antenna radiation properties through constructing lens antennas which is made in control Metamaterial. This project is of great scientific significance in reconfigurable antenna techniques on the basis of control Metamaterial. The progress in this project will provide a new technical solution to pattern reconfigurable antennas, which has huge future applications in communications and radar systems.
