TWO-POLAR RADIATOR OF PHASED ANTENNA ARRAY WITH LIMITED SCANNING SECTOR Russian patent published in 2019 - IPC H01Q1/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna engineering. Device comprises a base, a first printed circuit board (PCB), on one side of which there is a screen electrically connected to the base, and on the opposite side there is a first anti-phase power divider (APS), which input is electrically connected to the first polarization coaxial cable (CC) central core, the second PCB of rectangular shape, on one side of which the screen is electrically connected to the base, and on the opposite side there are exciters of the first, second, third and fourth emitting element, the transverse axis of symmetry of each of which is parallel to the short one, and the longitudinal axis – to the long side of the second PCB of rectangular shape, the second APS, the input of which is electrically connected to the central core CC of the second polarization, as well as the first, second, third and fourth in-phase power dividers of Wilkinson (IPDW), outputs of the second APS are electrically connected to inputs of the third and fourth IPDW, and inputs of the first and second IPDW are electrically connected to corresponding outputs of the first APS. First polarization CC screen is electrically connected to the first PCB screen, and the second polarization CC screen is connected to the second rectangular PCB screen. Named exciters of the first, the second, the third and the fourth radiating element are located so that the center of symmetry of each of them is in corresponding top of the rectangle, which sides are parallel to corresponding sides of the second rectangular PCB. Outputs of the first and second IPDW are electrically connected to corresponding first supply points (SP), and outputs of the third and fourth IPDW are connected to corresponding second SP exciters of the first, second, third and fourth emitting element. First SP of each exciter is located in the point closest to the edge of the second PCB of rectangular shape of intersection of longitudinal or transverse axis of exciter symmetry and exciter border, and the second SP of each exciter is located in the closest to the edge of the second rectangular PCB a point of intersection of the transverse or longitudinal axis of symmetry of the exciter and the boundary of the exciter, respectively. Above each of said exciters there is passive element (PE) of radiating element, center of each of which is electrically connected to center of corresponding exciter and to rectangular metal base, transverse axis of symmetry of each PE is parallel to short, and longitudinal – to long side of second PCB of rectangular shape, each of PE contains two cuts located symmetrically relative to center PE, symmetry axes of which pass through the PE center and are located so that the angle between them and the straight line passing through the first and second SP of the corresponding exciter does not exceed 5 degrees.

EFFECT: disclosed two-polar radiator of phased antenna array with limited scanning sector.
