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 transmission / receiving systems. In the antenna three separate emitters for GNSS, AM, and DW1 bands are used. GNSS band emitter is made spiral and is located at the antenna base. Emitters for the AM and DW1 bands are made of sets of metal tubes and dielectric bushings, ending with the conductive cable, and in their feeder lines coaxial cables sections chokes are installed.
EFFECT: invention allows to reduce the SWR, simplify the design, and improve operating in three bands (GNSS, AM, DW1) antenna usability.
