METHOD FOR CONSTRUCTING A TWO-FREQUENCY ANTENNA ARRAY Russian patent published in 2022 - IPC H01Q21/30 H01Q21/24 G01S13/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering and can be used in receiving and transmitting APAA. A method is proposed in which L-band slit emitters are used, while combining X-band emitters into sublattices that are placed between L-band emitters. X-band sublattices with a size of 8x8 printed emitters for two polarizations are used, containing eight 8-element antenna lines, which are located close to each other with long sides. The L-band slot antenna array is placed under the X-band sublattices, the pitch of the L-band slot emitters is set to 8 times the pitch of the X-band emitters, and they are placed between the corners of the X-band sublattices. A resonator with conductive walls is placed under each slot emitter of the L-band. The L-band emitter is performed in the form of two crossed slots, while the excitation of the slots for each polarization is performed using two pins. In the case of placement of X-band receiving and transmitting modules between the X- and L-band antenna arrays, through metallized holes are made in the housing of the X-band receiving and transmitting modules at the locations of the L-band slot emitters in the housing of the X-band receiving and transmitting modules, repeating the shape of the L-band slot emitters.

EFFECT: possibility of electronic scanning of the radiation pattern in two planes.
