International Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.Enhancing antenna gain remains a key requirement in modern wireless systems, particularly with the rapid evolution of 5G, emerging 6G networks, satellite links, and high‐resolution radar. Recent research trends increasingly rely on frequency‐selective surfaces (FSSs) and metasurface‐based reflectors, which offer precise electromagnetic wave control ...

Review of Wideband Passive Reflectarray Antennas
IEEE AccessReflectarray antennas (RAs) combine the high gain and low-loss space feed of reflectors with the per-element phase control of phased arrays, but their resonant, path-length-dependent operation makes bandwidth their principal limitation.

New Phase Realization Approach for Implementation of Braodband Reflectarrays
International Journal of Information and Communication Technology Research, 2021 We present a new phase realization approach applied to design the broadband single-layer reflectarray antennas. Such an optimization technique minimizes the adverse effects of frequency dispersion which limit the bandwidth of reflectarray antenna ...

Design of complementary reflectarray
Electronics Letters, 2014 A novel solution for the manufacture of a reflectarray antenna is presented. The unit cell simply consists of dielectric foam inserted between two thick metallic plates. The plate illuminated by the feeder is a 0.5 mm‐thick stainless steel sheet into which the C and the reverse C slots are laser cut.
