ANTENNA Russian patent published in 2021 - IPC H01Q11/10 

FIELD: antenna technology.

SUBSTANCE: invention relates to antenna technology, in particular to antenna-feeder devices of meter and decimeter wavelength ranges to provide a wide range of radar and radio communication tasks for stationary and mobile objects. The effect is achieved by introducing a second log-periodic antenna orthogonal to polarization located in a plane perpendicular to the plane of placement of the first log-periodic antenna, having the same structure and geometric dimensions as the first log-periodic antenna, and powered from its own symmetrical distribution line.

EFFECT: invention provides an increase in comparison with the prototype several times the number of spare operating frequencies due to the provision of the possibility of polarization detuning from group radio interference.
