DIGITAL ON-BOARD COMMUNICATION MEANS Russian patent published in 2021 - IPC H04B7/26 

FIELD: physics.

SUBSTANCE: invention relates to on-board data exchange systems and can be used for data exchange, for example, between aircraft and ground complexes in VHF, UHF and HF radio communication channels. Technical result is achieved as a result of use of four radio-optical transceiving modules, each of which contains n parallel branches, where n is not less than three, and each of n parallel branches consists of series-connected second optical detector, power amplifier, high-frequency switch, connected to antenna vibrator, low-noise amplifier and second optical modulator, and n antenna dipoles make a phased antenna array of the VHF and UHF bands of the radio-and-photon transceiving module, to which they enter, wherein the directivity patterns of the four radio-optical transceiving modules are shifted relative to each other by 90°.

EFFECT: higher reliability of transmitting information by eliminating distortion of parameters and shape of radio signals due to characteristics of radio-frequency cables in antenna-feeder paths and improving electromagnetic compatibility of communication means of the system.
