Fragment stripline controlled multielement phased array antenna (PAR) L band antenna relates to the art, in particular to multi-element strip-microwave (RF) antennas, and can be used both alone and in complex transceiver systems. Technical result of utility model - improved technical and economic characteristics in terms of workability, manufacturing cost reduction and expansion of frequency bandwidth. Said technical result is achieved in that, in the stripline PAR fragment containing the total passive reflector, symmetrical half-wave vibrator RF connectors and cable arranged along 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 vibrators which are fed through radio frequency (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 loop (RRSH) in communication with the window side of 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 U knee, the distance from the middle of the shoulder to a common printed vibrator passive reflector is λsr / 4. Moreover feeds the RF cable is placed on the one side of the PCB along the symmetry axis of the vibrator, and on the reverse side of the printed circuit board has a short-circuited balun which is formed on the coupled strip lines to a U knee with the modified topology of inclined in horizontally disposed symmetric relative to the symmetry axis of the vibrator. RF cable to reduce interference to the balun (U knee) crosses it at right angles and located. U knee derived to the input terminals and formed of two Π shaped sections of coupled strip lines λsr / 8 long. Strip lines are connected in series with each other, the total length U of the knee λsr / 2. In addition to expanding the frequency bandwidth, and increasing the resonant length dipoles shoulders topology vibrators formed with bends 90 ° towards the common passive reflector fold and in places matching bevels introduced at 45 °.
