Abstract
A novel unit cell for transmitarrays with innovative design based on a double-square slot frequency selective surface;
Ability to independently control vertical and horizontal polarisation bandpass filtering, distinctly acting as a polarising filter, by means of electronic tuneable biasing network;
Transmitarray enabled to perform beamsteering in two dimensions (azimuth and elevation, of at least 25 degrees in each plane) with polarisation diversity, by means of electronic tuneable biasing network.
