IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.This paper presents a broadband 1‐bit reconfigurable transmitarray operating at 11.7 GHz, using interdigital structures to achieve a 23.1% 3‐dB transmission‐loss bandwidth without requiring an air gap. An EM‐acquired CRCS‐based link gain model is developed to evaluate the radiation gain, scattering characteristics and gain‐frequency response of the RTA.

Electronics Letters, 2003 It is shown that the dominant factor controlling reflectarray bandwidth is the bandwidth of the radiating element, and that the effect of non-constant path delays over the surface of the flat reflector has little significance unless the aperture is electrically very large and the f/D ratio is small. An example of a polarisation-twist reflectarray using

On the Role of Reflectarrays for Interplanetary Links
IEEE Open Journal of the Communications SocietyInterplanetary links (IPL) serve as crucial enablers for space exploration, facilitating secure and adaptable space missions. An integrated IPL with inter-satellite communication (IP-ISL) establishes a unified deep space network, expanding coverage and reducing atmospheric losses.
