FIELD: radio engineering.
SUBSTANCE: antenna system includes waveguide-slot antenna array (WSAA) with centimetre wave band with radiating slots made in wide walls of feeding waveguides. Radiating surface of WSAA is made in the form of flat metal reflecting phase corrector that represents concentric steps of various width and height, which provide in-series phase correction of 0° to 360° with chosen discrete in millimetre wave length band.
EFFECT: possibility of simultaneous operation of antenna device in two rather different frequency bands at using the same radiating aperture and providing radiation characteristics in both bands close to extreme ones.
