OPTICAL PHASED ANTENNA ARRAY Russian patent published in 2015 - IPC H01Q21/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to phased antenna arrays. An optical phased antenna array comprises a bundle of optical fibres, the ends of which, on one hand, make up the plane of the phased antenna array and, on the other hand, make up an optical radiation receiving-transmitting plane, a matching optical system for uniform distribution of optical radiation from a laser across the entire receiving-transmitting plane of the bundle of optical fibres; each fibre is insulated from the coatings of other fibres; one of the "capacitor" coatings is in contact with the corresponding element on current-conducting rubber, which is connected to the corresponding contact at a "lower" plate, and the other is in contact with a common bus through current-conducting rubber, where there is a common contact for all "upper" coatings of the "capacitors". Such one-dimensional arrays are gathered one over the other to form a matrix. The optical radiation phase is controlled through the "lower" plates by a system for controlling, synchronising and processing information through digital-to-analogue converters.

EFFECT: wider range of equipment for realising an optical phased antenna array.
