ABSTRACT:
A planar scanning antenna is configured for scanning and tracking. In one embodiment, the planar scanning antenna may include a transducer module configured to provide an electromagnetic beam. According to another aspect of the invention, the apparatus may include a first planar dielectric element having an axis of rotation and configured to direct an electromagnetic beam. In one embodiment, a second planar dielectric element oriented adjacent to the first planar dielectric element and having the axis of rotation may be configured to direct electromagnetic energy. The apparatus may further include a mounting structure arranging the transducer module and the first and second planar dielectric elements. In yet another embodiment, the apparatus may include a drive means for positioning the first planar dielectric element independently from the second planar dielectric element.
