Abstract

A novel tunable E-band (78–82 GHz) Reconfigurable Electro-Mechanical Reflectarray (REMR) is demonstrated for beam focusing and steering. This design is based on our previous study, which achieved a 350° phase dynamic range in simulations, and is experimentally validated here. The results confirm precise beam focusing and ±3° beam steering, showing excellent agreement with simulations. To further enhance performance, an innovative dual-patch unit cell with a flat ground plane is introduced, enabling nearly 360° phase coverage and extended beam steering up to ±6°. The simplified architecture reduces fabrication complexity and cost while providing a compact, robust, and power-efficient solution for E-band and millimeter-wave communication systems.
