ANTENNA RADIATOR Russian patent published in 2017 - IPC H01Q9/00 

FIELD: radio engineering, communication.

SUBSTANCE: antenna radiator includes a flange and two vibrators. Each vibrator is equipped with a dielectric substrate with metallization, a feeding line and a group of contacts for connecting the transceiver equipment. The flange of antenna radiator in plan is made in form of circle, which is made up of sectors of flat plates with borders flanked at the edges along the radius. The dielectric substrate of each vibrator is made flat. The metallization on dielectric substrate is made of at least a pair of metallized patterns, first applied on the front side and a second on the back side of dielectric substrate. Wherein, the first metallized pattern is made of two loop-backs, each of which is provided with a shoulder and a strip, freed from metallization. The second metallized pattern is made of a single loop-back, which is provided with two symmetrical, multidirectional shoulders. And the vibrator loop-backs are located along the longitudinal axis of the antenna radiator. In the loop-backs through the dielectric substrate, the upper transition holes are made for the connection of metallized patterns elements, and the lower transition holes for the elements of connecting the vibrators to the flange. The feeding line is stretched in the band of loop-backs of the first metallized pattern of each vibrator, which has been freed from metallization. The group of contacts for connecting the transceiver equipment of each vibrator includes a central contact, connected to the initial point of supply line, and the side contacts, which are located near each other in area of first metallized pattern lower part. The side contacts are connected respectively to each loop-back of first metallized pattern and to loop-back of second metallized pattern. In addition, vibrators planes are interconnected crosswise and are installed between the walls of flanged edges of sectors perpendicular to flange plane with the possibility of electrical contact by means of fastening the elements which are located in the lower vibrator junctions, aligned with the flanged edges junctions of flange sectors.

EFFECT: obtaining the desired shape of radiated pattern and reducing the side lobes of antenna radiator.
