DUAL-BAND EMITTER FOR ANTENNA ARRAY Russian patent published in 2021 - IPC H01Q9/28 

FIELD: ultra-high frequency technology.

SUBSTANCE: invention relates to ultra-high frequency (UHF) technology, in particular to antennas; it can be used in dual-band antenna arrays, including phased ones, communication technology and radar devices. The emitter is a flat wideband vibrator containing vibrator arms, a balancing device of a U-knee type connected to vibrator arms by means of a connection line consisting of two parallel conductors. The vibrator arms are made in the form of trapezoid, the lateral sides of which have different lengths, bases are parallel to conductors of the connection line, and the long lateral side faces the U-knee. The conductor of the connection line has direct galvanic contact with the vibrator arm along the entire length of the short trapezoid base. Holes are made in the vibrator arms. The end of the conductor of the connection line forms an obtuse angle with the short lateral side of the trapezoid.

EFFECT: technical result is obtaining vibrator emitters of a special shape as emitting elements in dual-band antenna array due to improving emitter matching in the composition of antenna array with retaining low weight and size parameters and high manufacturability.
