ACTIVE TRANSMITTING BROADBAND ANTENNA DEVICE OF MW-RANGE Russian patent published in 2020 - IPC H01Q9/00 

FIELD: antenna equipment.

SUBSTANCE: invention can be used for radiation of medium-wave (MW) range radio waves. Technical result is achieved due to fact that in active transmitting broadband antenna device of medium-wave range, using method of electromagnetic waves excitation, at which each period of harmonic oscillation is divided into N pulses of rectangular shape of equal amplitude, the sum of which reproduces harmonic signal, wherein each pulse is formed by one of N active elements operating in a key mode, the number of rectangular pulses and the number of active elements is assumed equal to 200, each active element comprises vertically mounted round copper cylinder—emitter with length of 1 meter, outer diameter of 0.04 meters, inner diameter of 0.02 meters, in series with radiator there is a resistor with nominal value of 10 Ohm, lower end of emitter is grounded, and active device is fixed on upper end, all radiators are placed at a distance of one meter from each other on a circle with length of 200 meters, radius of 31.83 meters.

EFFECT: technical result is creation of broadband antenna device of MW-band with active radiators without adjustment elements in whole medium-wave range, which makes it possible to use noise-immune mode of operation with pseudorandom frequency tuning in this range.
