LINEAR MAGNETIC ANTENNA FOR HIGH-FREQUENCY RANGE Russian patent published in 2019 - IPC H01Q7/08 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering and is intended to extend the possibility of using LMA-type transmitting antennas related to the form of Hertz linear magnetic dipoles (MHD) for HF radio waves. Technical effect is achieved due to the fact that in a transmitting linear magnetic antenna for HF range (LMAHF) containing electrically conducting cylindrical body enclosed in a dielectric cylinder, arranged in cylindrical magnetic conductor enveloped with winding of single-layer solenoid of HF longitudinal magnetic flux excitation, having dielectric cylindrical shape frame arranged on cylindrical magnetic conductor, wherein the near end of the solenoid winding is configured to be connected to one of the ends of the electrically conductive cylindrical body, the ends of which are connected to the corresponding input terminals of the HF voltage source, and electrically conductive cylindrical body is included in the gap between one of terminals of HV high-voltage source and one of ends of solenoid winding, when its other end is connected to other source terminal, wherein the electrically conductive cylindrical body is configured to extend beyond the ends of the enveloping dielectric cylinder thereof or part thereof can be in the form of a telescopic metal antenna.

EFFECT: technical result consists in improvement of efficiency of operation (radio communication) of antenna for transmission, reduction of dimensions of antenna with possibility of use in range of HF radio range from 600 to 10 m that is range of action of signal propagation.
