Abstract :
A fabricated reflectarray design has been presented showing the possibility of using elements of various heights to design reflectarray systems with steerable beams. A static prototype has been fabricated to show the technique. MEMS technology can be used to manufacture elements that have variable heights which can be used to continuously shift the re-radiated phase, steering the main beam of the antenna.
