METHOD OF CONSTRUCTING PRINTED EMITTER WITH CIRCULAR POLARIZATION Russian patent published in 2024 - IPC H01Q1/38 H01Q3/26 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna engineering, namely to methods of constructing radiators for antenna arrays with rotating field polarization and can be used for antenna systems for satellite communication. Disclosed is a method of constructing a printed emitter with circular polarization from a pair of crossed dipoles, where the first arms of the first and second dipoles are made on one side of the printed circuit board, the first arms of the first and second dipoles are connected with a printed jumper with a length of λ/4, where λ is the wavelength of the middle of the operating frequency range, the second arms of the first and second dipoles are made on the other side of the printed circuit board, the second arms of the first and second dipoles are connected with a printed jumper λ/4. First and second arms of first and second dipoles are triangular, and the printed circuit board with the emitter is fixed above the conducting screen on a stand, which is a rectangular printed board with a communication line through which the emitter is supplied, the stand width is not more than 1/2 of the length of the emitter arms, wherein the upper end of the stand is inserted into a rectangular hole in the printed circuit board with an emitter so that the upper edge of the stand protrudes above the upper plane of the printed circuit board.

EFFECT: reduced weight of printed emitter with circular polarization.
