ANTENNA Russian patent published in 2018 - IPC H01Q9/16 

FIELD: antenna equipment.

SUBSTANCE: invention relates to the ultra-wideband antennas with vertical polarization and circular radiation pattern in the horizontal plane, and can be used in information transmission / receiving systems. Antenna contains a base including a cup, a shock absorber, the first dielectric bushing with the Edison thread on the outer surface, connector, matching transformer, and two pieces of cable. Lower sub-band emitter includes the second dielectric bushing with the Edison thread. Connector counterpart is located inside the second dielectric bushing with possibility of the counterpart connection to the connector receiving part. At the end faces the second dielectric bushing is provided with connected by the conductive strip contact rings. Between two metal tubes the hollow and dielectric insert is located. Cable third section is located inside the second dielectric bushing, the first metal tube, the insert and the second metal tube. Upper sub-band emitter includes the third dielectric bushing, the third metal tube, the spiral coil, the conductive cable and mounted on the third cable section outer surface inside the third dielectric bushing ferrite rings.

EFFECT: invention allows to reduce the SWR, simplify the design, reduce the antenna longitudinal dimensions and improve the usability.
