NONDIRECTIONAL ANTENNA IN HORIZONTAL PLANE Russian patent published in 2016 - IPC H01Q1/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to antenna engineering, particularly, to design of transmitting antenna for operation with wideband radio transmitting devices. Summary: nondirectional antenna in horizontal plane has input in form of housing, inside of which passes coaxial cable, which interacts with connector, input and fixed on housing with coaxial metal rods conductors, arranged inside of insulator consisting of two longitudinal halves fixed to lead by semicylinder, coaxial metal rods conductors have grooves interacting with projections on inner part of insulator, one end of coaxial metal rod conductor interacts with coaxial cable and other end has threaded part interacting with metal cylinder vibrator in form of sleeve set on insulator and interacting via insulators in form of rings with metal rings by vibrators, at outer diameter of all elements of nondirectional antenna in horizontal plane are fixed by shell with inserts and heat shrinkable tubes.

EFFECT: this technical solution enables to obtain nondirectional antenna in horizontal plane with rigid structure, in which structural capacity and coaxial lines allow to produce bandwidth - coefficient of overlapping by range f_max/f_min≥2, stability of beam pattern - circular beam pattern, which lies in azimuthal plane in entire operating band.
