MULTILAYER PRINTED CIRCULAR POLARIZED PHASED ANTENNA ARRAY WITH WIDE-ANGLE SCANNING (OPTIONS) Russian patent published in 2021 - IPC H01Q1/38 H01Q9/06 H01Q21/06 

FIELD: antenna technology.

SUBSTANCE: inventions group relates to the field of antenna technology, and more specifically to antennas based on multilayer printed circuit boards technology, and can be used in the design and manufacture of antenna phased arrays with an electrically controlled directional pattern, forming a beam with circular polarization. The multilayer printed emitter according to the first embodiment is made in the form of a multilayer board containing six metallization layers separated by dielectric layers. The first metallization layer includes passive elements of four radiating elements. The second metallization layer includes emitting element drivers, each of which is located under a corresponding passive element, the center of each of which, in turn, is electrically connected to the center of the corresponding driver. Each of the mentioned pathogens and passive elements is made in the form of a square with cut off opposite corners. The mentioned exciters and passive elements are located in such a way that the center of symmetry of each of them is at the corresponding vertex of the square, and the longitudinal axis of symmetry of all exciters and corresponding passive elements is parallel or perpendicular to the square diagonal passing through the exciter. The third metallization layer includes four slots, each of which is located under the corresponding exciter and is made in such a way that it has two symmetry axes perpendicular to each other, the longitudinal symmetry axes of which form an angle of 45 degrees with the longitudinal symmetry axis of the corresponding exciter. The fourth metallization layer includes four strip lines, each of which is electromagnetically connected with a corresponding slot and with four strip lines of the sixth metallized layer, which are configured to be connected to the input or output of the radiating element. The mentioned exciters and passive elements are located in windows in which there is no metallization layer, and the metallization layers around them are electrically connected by metallized holes located around each radiating element to each other, with the third metallization layer and the fifth metallization layer, which are grounding. The multilayer printed emitter according to the second embodiment is distinguished by the fact that it contains four pairs of slots, with one slot from each pair electromagnetically connected (by means of strip lines) with a matched load.

EFFECT: simplifying the design of the emitter and manufacturing technology without deteriorating (and in the case of the second embodiment of the invention with a significant improvement) radio technical characteristics.
