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 ...

A Ku-Band Foldable Reflectarray Based on a Maltese-Cross Microstrip Element
Известия высших учебных заведений России: Радиоэлектроника, 2021 Introduction. Reflectarrays have a number of design and functional advantages over their closest analogue - reflector antennas (RA). Although microstrip elements are the most preferred reflectarray elements, single-layer microstrip elements do not allow ...
