FIELD: radio engineering.
SUBSTANCE: antenna system consists in signal port for received radio signals output, upper antenna element and lower antenna element located coaxially under it. Upper antenna element includes: radiating plate, located over screening plate, lower antenna element consists in screening plate under which there located is flat plate. Upper and lower antenna element has different degree of electro-magnetic interaction with signal port. Radiating plate of upper antenna element and/or screening plate of upper antenna element and/or plate of lower antenna element and/or screening plate of lower antenna element, at least, at two opposite sides is performed with bended elements. Also there proposed is compact dual-band antenna system for radio signal receiving. There used are bended elements at the plates in a form of different ribs and combs.
EFFECT: increase of antenna frequency working range, sizes decrease, structure simplification.
