FIXED VERTICAL OMNIDIRECTIONAL ANTENNA OF HECTOMETRE WAVELENGTH RANGE Russian patent published in 2024 - IPC H01Q9/00 

FIELD: antennae.

SUBSTANCE: invention relates to a stationary vertical omnidirectional antenna in the hectometre range. Antenna comprises an emitter and a matching system, the emitter comprises a shortened quarter-wave dipole, a dielectric radiotransparent casing, the first and second brackets fixed on the casing, a grounding feedthrough terminal, matching system comprises a matching module connected to a radiator and a power supply module connected through a power and control adapter to the matching module. First and second brackets are made with bases, by means of which the emitter is attached to the support mast, wherein the base of the second bracket located on the casing below the first bracket is made of a metal material, wherein the grounding feedthrough terminal is fixed on the base of the second bracket. Power and control adapter is connected to the transceiver of the hectometre wavelength range, wherein the matching module is placed on the support mast under the antenna radiator, and the power and control adapter and the power module are located at the location of the hectometre wavelength range transceiver, wherein the power and control adapter is designed to power the matching module for matching the antenna with the transceiver.

EFFECT: reduced overall dimensions without deterioration of electrical parameters of the antenna while ensuring accuracy of matching and safety.
