ARRAY SCANNER FOR OBTAINING A MILLIMETER-WAVE IMAGE BY EFFICIENTLY CONTROLLING A SIDELOBE LEVEL

摘要

PURPOSE: An array scanner for obtaining a millimeter-wave image is provided to prevent a grating lobe by arranging a plurality of radiation patches in a limited space.;CONSTITUTION: A radiation patch(110) is formed on one side of a dielectric substrate(100) and resonates at a specific frequency band. A ground surface(180) is formed on the rear of the dielectric substrate. The width of the radiation patch is determined according to an electric length of a slit. The slit has a fractal shape.;COPYRIGHT KIPO 2013;[Reference numerals] (100) Dielectric substrate; (110) Radiation patch; (130) Beam former; (170) SMA connector; (180) Ground surface
