METHOD OF FORMING CARDIOID BEAM PATTERNS USING COMPOSITE SMALL-SIZE SUPERDIRECTIONAL HIGH-FREQUENCY ANTENNA Russian patent published in 2024 - IPC H01Q9/00 

FIELD: radio communication.

SUBSTANCE: invention relates to radio communication, in particular to composite small-size directional antennas for phased antenna arrays of HF range. Disclosed is a method of forming cardioid beam patterns using a composite small-sized superdirectional HF antenna based on vertically radiating sections, within which there are connected first and second generators or low-noise amplifier, connected to each other by a double-wire line and spaced apart relative to each other by a distance less than a quarter of the smallest wavelength of the operating frequency range of the transmitted signal, and generator or low-noise amplifier have equivalent resistance equal to wave impedance of two-wire line, wherein the double-wire line has the shape of a rhombic radiator when the rhombus plane is located vertically relative to the ground for inclusion in the mechanism of radiating or receiving radio waves.

EFFECT: simultaneous multifrequency omnidirectional reception with a high level of suppression of the back lobes of the beam pattern and high stability of radio communication.
