FIELD: radio engineering, communication.SUBSTANCE: invention relates to electronic equipment, particularly a transmitting antenna structure for radio jamming receiving devices of electronic communication means, data transmission means, electronic and navigation equipment of consumers of network-based medium-altitude satellite navigation systems. The transmitting antenna has a reflecting shield in form of a cylindrical pipe with radiators mounted on its surface at equal distances from the axis of the cylindrical pipe in one plane, perpendicular to the axis of the cylindrical pipe, which enable to form a circular beam pattern when interfering signals are transmitted to all radiators at the same time, said interfering signals having the same initial phase of oscillation of the carrier frequency, and forming a sector directed towards the position in the azimuth plane of the beam pattern, said sector having a high energy potential of radiation when interfering signals with given ratios of initial voltages and phases of the carrier frequency are transmitted to the radiators. The cylindrical pipe is involved in both formation of the required beam pattern of the transmitting antenna and providing rejection of the negative effect on beam formation of power cables of the radiating elements.EFFECT: forming, in the azimuth plane depending on the situation, a beam pattern either maximally close to circular with uniform distribution of energy potential or with a high energy potential in a given sector of radiation of radio frequency interference.6 dwg |
