DUAL-MODE SMALL-SIZE SLIT STRIPLINE ANTENNA FOR HIGH-PRECISION POSITIONING BY SIGNALS OF GLONASS, GPS, GALILEO, BEIDOU Russian patent published in 2024 - IPC H01Q13/10 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna engineering, in particular to leaky-wave circularly polarized slit stripline antennae, and is used to receive signals from global navigation satellite systems. Disclosed is a two-mode small-sized slit stripline antenna for high-precision positioning based on GLONASS, GPS, Galileo, Beidou signals, including a dielectric substrate, which is metallised on both sides, in the metal of the upper side of which the main slit radiators are made with an increase in the width of the slit in the antinode of the high-frequency electric field of the main oscillation mode of the H-wave, which are spirally twisted around the geometric centre of the antenna, not connected to each other and including straight and curved segments of different length, characterized in that to the main slit radiator section, increased in width in the high-frequency electric field antinode of the main oscillation mode of the H-wave, additional slits directed along the main slit radiators and not crossing them are connected by the end side.

EFFECT: wider operating frequency band of the antenna.
