MICROSTRIP ADAPTIVE-POLARIZATION ANTENNA ARRAY Russian patent published in 1998 - IPC

FIELD: microwave antennas with polarization adapted to transmitted and received signals. SUBSTANCE: antenna array designed for operation with any type of linear polarization arbitrarily oriented in sector of angles from 0 to 90 deg. and with any type of circular polarization (right- and left-hand, with low level of side lobes) has even number of rectangular radiators whose centers are located in nodes of coordinate scale and spaced apart by gaps. Central rectangular radiators have one of their sides equal to wavelength and other, adjacent, side equal to half the wavelength; remaining radiators are square- shaped with sides equal to wavelength. Exciting members made in the form of metal rods are connected to each central radiator in center of side edge. EFFECT: enlarged functional capabilities. 5 cl, 6 dwg
