Abstract

Антенная решетка, включающая отражатель и излучатели, каждый из которых содержит симметричный вибратор, выполненный в виде двух плоских металлических элементов, имеющих одинаковые прямоугольные плечи, внешний и внутренний проводник для подключения симметричного вибратора к внешней линии передачи сигнала, при этом излучатели расположены перпендикулярно к плоскому металлическому отражателю, плоскости излучателей расположены вдоль оси антенной решетки, отличающаяся тем, что проводники подключения вибратора выполнены в виде плоской воздушной трехпроводной линии передачи, содержащей два внешних проводника, на которых крепятся плечи симметричного вибратора и расположенный между ними внутренний проводник, излучатели расположены на отражателе в две линейки по четыре излучателя в каждой, причем центры излучателей в верхней линейке смещены относительно центров излучателей в нижней линейке на половину расстояния между излучателями, отражатель имеет восемь прямоугольных отверстий, центры которых совпадают с проекциями центров излучателей на отражатель, предназначенные для соединения внутреннего проводника каждого вибратора излучателя с внешней линией передачи сигнала, левый и правый боковые края отражателя скошены под углом к нижнему краю отражателя, вдоль периметра отражателя выполнено обнижение поверхности, на котором расположена канавка для установки токопроводящей прокладки, при этом размещение линеек излучателей на отражателе обеспечивает сохранение шага расположения излучателей в соседних антенных решетках при установке любого количества антенных решеток рядом друг с другом на одну несуAn antenna array including a reflector and emitters, each of which contains a symmetric vibrator made in the form of two flat metal elements having the same rectangular shoulders, an external and internal conductor for connecting a symmetric vibrator to an external signal transmission line, while the emitters are perpendicular to the flat metal the reflector, the plane of the emitters are located along the axis of the antenna array, characterized in that the conductors connecting the vibrator are made in the form of a flat a three-wire airborne transmission line containing two external conductors on which the arms of the symmetrical vibrator and the inner conductor located between them are attached, the emitters are located on the reflector in two lines of four emitters in each, and the centers of the emitters in the upper line are offset from the centers of the emitters in the lower line by half the distance between the emitters, the reflector has eight rectangular holes, the centers of which coincide with the projections of the centers of the emitters on the reflector, are designed e to connect the inner conductor of each vibrator of the emitter with the external signal transmission line, the left and right side edges of the reflector are beveled at an angle to the lower edge of the reflector, along the perimeter of the reflector, the surface is diminished, on which there is a groove for installing a conductive strip, while placing the emitter lines on the reflector ensures that the spacing of the emitters in adjacent antenna arrays is maintained when any number of antenna arrays are installed next to each other on one carrier
