DEVICE FOR MEASURING AMPLITUDE-PHASE DISTRIBUTION OF ANTENNA FIELD Russian patent published in 2015 - IPC G01R29/10 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio measurement. The device comprises a rotary platform connected through a planetary gear to an axial engine and mounted by a bearing block on a fixed horizontal base placed on metal supports, a generator connected by a waveguide through a switch to an annular irradiator, and a planar scanner consisting of a bogie mounted on a horizontal guide and, mounted on the bogie, a vertical guide with a carriage and a measuring probe, which is connected through a mobile communication line to the first input of an amplitude-phase meter, the output of which is connected to the first input of a recorder. A coordinate drive is connected to the bogie and the carriage, which is optically linked to a coordinate sensor. The device also includes a rotary supporting base connected to the axial engine through a reverse-reduction gear, a bitwise comparison unit, a valve register, a matrix markup code sensor, an irradiator markup counter and a shaft position-to-digit converter. A reflector mirror is mounted on the periphery of the rotary platform, on the axis of which there are annular irradiators connected to the reverse-reduction gear. On the axis of the rotary supporting base there is a rotating adapter which connects the output of the generator with the reference input of the amplitude-phase meter.

EFFECT: higher accuracy and faster measurement of antenna characteristics.
