Periodical diffraction grating of holes in metal disc has low weight and is easy to manufacture. Corresponding antenna model is shown. Antenna operates on 12.5 GHz, has 3.3\u00b0 x 3.3\u00b0 main beam, and has an option of beam steering within \u00b130\u00b0 sector. Initially this model was designed for high-resolution satellite radar system with synthesized aperture. With some modifications it can be used in scanning mode in helicopter landing radar system, marine mooring system and others<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
