The invention relates to antenna technology, in particular to multi-element strip-microwave (RF) antennas and may be used as a fragment of a phased array antenna (PAR), both alone and in complex transceiver systems, such as modern radars. Technical result of utility model - improved technical and economic characteristics in terms of workability, manufacturing cost reduction, conservation of a wide frequency band, for saving parameters PAR fragments that have been implemented in the patents. Said technical result is achieved in that, in the stripline PAR fragment containing the total passive reflector, symmetrical half-wave vibrator, and a cable radio frequency (RF) connectors are arranged on the symmetry axis vibrators on the level of the passive reflector, which serve as the structural member for mechanically fixing printed circuit boards. Each vibrator formed on one double-sided printed circuit board with two arms connected to each other via a communication gap located along the symmetry axis of the vibrators. Shoulders vibrator powered via RF cable in antiphase upper supply circuit. On one of the sides perpendicular to the printed circuit board and symmetrically with regard to the gap between the printed dipole arms disposed open jet plume connection with window toward the vibrator and electrically connected to the shoulders of the vibrator. Also on the printed circuit board taken shorted balun formed on the coupled strip lines to a horizontally oriented U knee. The distance from the middle of the shoulder to a common printed vibrator passive reflector is λsr / 4. The topology of the half-wave printed dipole arms is formed as a rectangular conductors symmetrical along the symmetry axis of the vibrators. Again the shoulders topology vibrator jet plume and open communication with the window in the direction of the vibrator are disposed on one side of the PCB, and feeds the RF cable and short-circuited balun placed on the other side of the PCB along the symmetry axis of the vibrator. To ensure the same potential 2-sided printed dipole excitation point vibrator galvanically short via hollow rivets and to ensure the closure further connected by soldering.
