Millimeter wavelength imaging system based on Flat Parabolic Surface

In this study we will present ongoing research and development of millimeters wavelength (MMW) imaging system based on Flat Parabolic Surface (FLAPS). The conventional reflector antennas used for MMW imaging systems are mechanically cumbersome, complicated for manufacturing and therefore are very expensive. In this study we propose to use FLAPS technology, instead of the conventional reflectors in MMW imaging systems. FLAPS are composing of metal patterns printed on dielectric substrate. In this work we will use copper patterns printed on FR4 substrate much like the common printed circuit boards (PCB´s) used in the electronic industry. This will make the manufacturing process of MMW large aperture mirrors for imaging systems very cheap and light weight. Theory, metal patterns and simulation results will be presented in this work.
