FIELD: radio engineering.SUBSTANCE: arms of a symmetrical vibrator of metric waves are made from flat plates, which are fixed to external conductors of a balancing device arranged in the form of a three-wire flat overhead transmission line. The upper part of the central conductor of the balancing device is connected with one of vibrator arms, and its lower part is an input of the vibrator and has a narrowing transition for connection to the external line of signal transmission, at the same time side edges of vibrator arms are bent at the right angle in direction of the screen. Fixation of vibrator arms to the balancing device is arranged with an incline of 45° in direction of the screen, side surfaces of vibrator arms are additionally connected with external conductors of the balancing device by walls of triangular shape. Side edges of external conductors of the balancing device are bent at the right angle inside, the upper parts of the vibrator arms are connected to each other with the help of a dielectric plate. The lower part of the left external conductor of the balancing device is bent at the right angle to the left, and the lower part of its right external conductor is bent at the right angle to the right.EFFECT: increased width of directivity pattern, higher vibration strength and efficiency of vibrator installation.4 dwg |
