Abstract: This paper presents the design, fabrication, and experimental validation of a Ku-band 3D-printed reflectarray (RA) antenna established on a quasi-periodic arrangement, operating at 13 GHz.

Abstract: With the electromagnetic spectrum becoming increasingly crowded, reconfigurable transmitter arrays can use spatial diversity to avoid interference. Tunable reflectarrays provide a useful ...
