An auto-focusing lens module includes a substrate, guiding members positioned on the substrate, an actuator unit, a driving plate, and a lens holder holding a lens therein. Arrays of halftone threshold values are used to determine a desired orientation, e. The present invention realizes the first application of the cold island effect principle in the technical field. Each connector comprises a first surface and a second surface. In addition, the method includes calibrating the antenna elements of each antenna array using the calibrated calibration circuits.
