SLOT ANTENNA Russian patent published in 2022 - IPC H01Q11/10 

FIELD: antenna technology.

SUBSTANCE: invention relates to antenna technology, namely to antenna-feeder devices of meter and decimeter wavelength ranges, and serves to increase the reliability of surface radio communication systems in conditions of a complex interference situation and extreme natural and climatic conditions. The expected result is achieved by the fact that in the new design of the log-periodic antenna, V-shaped wedge-shaped slot emitters with circles at pointed ends are used as active and passive vibrators, the geometric dimensions of which are calculated based on the applied sections of the meter and decimeter wave range, and in the screens that are metal braids and dielectric layers of cables of the antenna assembly line, annular sections for connecting screen metal braids of the cables of the collecting line from the right and left sides of the corresponding circles of the V-shaped slot emitters to ensure their excitation, while the wedge-shaped slot emitters of the antenna are cut into the trapezoidal metal cover of the endovibrator.

EFFECT: expansion of the range properties in a complex interference environment, as well as an increase in the mechanical reliability of the antenna design in extreme operating conditions.
