POLARIZED-ADAPTATION MICROSTRIP ANTENNA ARRAY Russian patent published in 1999 - IPC

FIELD: microwave antenna engineering. SUBSTANCE: antenna array designed for use in polarimeter radars, microwave imagers, medical electromagnetic overlay apparatuses, polarization-modulated signal information transmitting and receiving systems with any linear polarization oriented arbitrarily between 0 and 180 deg. , any circular and elliptical polarization, any type of polarization modulation, which ensures bimodal signal reception has even number of rectangular radiators mounted at rectangular graticule nodes and spaced apart through certain gaps. Central radiators of four relatively perpendicular beams of rectangular graticule are made in the form of rectangle one of whose sides is equal to wavelength, and adjacent one, to half of wavelength; remaining radiators are square-shaped with each side of square equal to wavelength. Exciting member is connected to each central four- beam radiator at point located in center of side edge. EFFECT: enlarged functional capabilities. 11 cl, 12 dwg
