DEVICE FOR AUTOMATIC MEASUREMENT OF ANTENNA DIRECTIONAL DIAGRAM Russian patent published in 2009 - IPC G01R29/10 

FIELD: physics; radio.

SUBSTANCE: present invention relates to radio engineering, to antenna measurements and can be used for analysing antenna directional diagrams of different radio systems. The device contains series-connected transmitter, directional coupler, device for measuring signal power, processing and control device and a first digital-to-analogue converter. The device for rotating the receiving antenna is mechanically connected to the axis of rotation of the receiving antenna. This axis is also connected to the angle of rotation sensor of the receiving antenna, whose outputs are connected to the second input of the processing and control device. The third input of this device is connected to the output of the receiver, the input of which is connected to the output of the receiving antenna. The second output of the processing and control device is connected to the input of the second digital-to-analogue converter. The output of the converter is connected to the device for rotating the test antenna, mechanically connected to the axis of rotation of the test antenna. This axis of rotation is also mechanically connected to the angle of rotation sensor of the test antenna, whose output is connected to the fourth input of the processing and control device. The first output of the directional coupler is connected to the input of the test antenna.

EFFECT: 2-3 times more accurate measurement due to statistical processing of measurement results, as well as cutting on measurement time by 3-4 times due to automation of the measuring process.
