This paper summarizes some of the growth in technology for Fresnel zone plate antennas in the microwave and millimeter-wave regions. A description is given of the earliest developments of Fresnel zone plates at optical frequencies. Most of the material concerns previous results obtained for microwaves and millimeter-waves.
