FIELD: radio engineering and communications.SUBSTANCE: invention is intended to construct phased antenna arrays from antenna-feeder devices of radio communication systems or radar. Arms of a symmetrical VHF dipole are made from flat plates attached to outer conductors of balancing device made up of three-wire flat overhead line whose outer conductors have same width as dipole arms. Upper part of central conductor of balancing device is connected to one of dipole arms, and its lower part is input of dipole, lateral edges of dipole arms are bent at right angle in direction of screen. Attachment of dipole arms to balancing device is made with inclination of 45° in direction of screen, side surfaces of dipole arms are additionally connected with external conductors of balancing device walls of triangular shape. Lateral edges of external conductors of balancing device are bent at right angle inside, conductors of balancing device are connected to each other by means of dielectric plates at two points. Lower part of left external conductor of balancing device is bent at right angle to left to form left part of flange mounting dipole to screen, and lower part of right external conductor of balancing device is bent at right angle to right to form right part of flange mounting dipole to screen, right and left parts of flange are interconnected by bridges.EFFECT: increased vibration strength of design of a dipole.1 cl, 1 dwg |
