Abstract

This paper introduces a novel, broadband, low-cost technique for beam steering at millimeter-wave frequencies using a moveable grating film fed by dielectric image line. An excellent radiation pattern is maintained over wide scan angles across the 30-40 GHz range, with up to 53° scanning reported at 35 GHz. Theoretical calculations closely predict the observed scan angle across the entire range of measurement.
