DEVICE FOR THE SIMULTANEOUS FORMATION OF ELECTROMAGNETIC WAVES WITH DIFFERENT NON-ZERO ORBITAL ANGULAR MOMENTUM AT THE SAME CARRIER FREQUENCY Russian patent published in 2022 - IPC H03C7/02 

FIELD: antenna technology.

SUBSTANCE: invention relates to the field of antenna technology and is intended for the simultaneous formation of electromagnetic waves with different non-zero orbital angular momentum at the same carrier frequency. To achieve the effect, the device contains a ferroelectric plate with a radio-transparent coating of two opposite sides, covered with plates of a linear dielectric at an operating frequency, taking into account the dielectric constant of the dielectric material. On the first side of the ferroelectric plate, the radio-transparent coating is divided into separate galvanically isolated electrodes using gaps made in the form of lines in the amount of at least two, emanating from the same center with the same angles between adjacent lines, as well as concentric circles in the amount of at least two with the center, coinciding with the point of intersection of the mentioned lines.

EFFECT: increasing the efficiency of frequency spectrum use and data transfer rate.
