RECONFIGURABLE LASER ANTENNA Russian patent published in 2023 - IPC H01Q1/38 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna equipment and is used for transmitting and receiving electromagnetic signals in a wide wavelength range, including wavelengths over 10 cm. The technical result is achieved by the optimal antenna structure for receiving and transmitting radio signals of the required spectral range and directivity being created the reconfigurable laser antenna by illuminating the semiconductor elements connecting a system of conductors secured on a dielectric surface by a laser radiation source; the resistance of the semiconductor elements in one or both directions of current during laser irradiation being reduced by more than one order of magnitude, providing an opportunity to shape the required antenna circuit; and control of the intensity of illumination of the semiconductor elements allowing switching between antenna circuits with different configurations.

EFFECT: higher reliability, improved electromagnetic compatibility parameters, the possibility of fast control of the receiving and transmitting characteristics of the antenna apparatus, structural simplification, and added possibility of optical control of the antenna parameters.
