FIELD: radio communication engineering. ^ SUBSTANCE: device has four plates and four segments of coaxial feeder. The plates are made from metal, have rectangular shape of various area and are arranged in parallel to each other. Centers of the four plates belong to the central axis and their long and short sides are arranged in parallel to each other, respectively. The central conductor of the first coaxial feeder segment is connected to the first plate and the external envelope of the first coaxial feeder segment is connected to the second plate. The central conductor if the second coaxial feeder segment is connected to the second plate at a greater distance from the central axis than the distance from the central conductor of the first coaxial feeder segment. External envelope of the second coaxial feeder segment is connected to the fourth plate. The central conductor if the third coaxial feeder segment is connected to the third plate and the external envelope of the third coaxial feeder segment is connected to the fourth plate. Omnidirectional aerial is set on the same side with the first plate. The fourth coaxial feeder segment of the omnidirectional aerial is in the central opening of al plates, its external envelope is connected to the first plate. ^ EFFECT: improved characteristic features. ^ 11 cl, 18 dwg |
