Abstract

FIELD: transmission and reception of linearly polarized waves. SUBSTANCE: antenna array has at least one antenna module incorporating four radiating members equidistantly arranged in one plane at square lattice nodes and cophasal waveguide power splitter where TE-o1 mode propagates. Power splitter has three identical T-joints in vector E plane whose four inputs are connected by means of rectangular waveguide sections, whose axes are perpendicular to vector E plane, to radiating members. Each radiating member has two plates with conducting surfaces tightly fitted to each other. First plate 1 has rectangular depression in central part on side facing second plate whose depth h approximately equals plate thickness. Center O of depression is located on longitudinal axis N-N of rectangular waveguide section; larger side c of depression is parallel to side a of rectangular waveguide section; made in each depression along larger sides, in immediate proximity of them, are four slits whose length e is about L/2 and their centers are at tops of square having side f smaller than L. EFFECT: improved design.

Сущность изобретения: высокочастотная плоская антенная решетка для приема/передачи линейно-поляризовнной волны содержит по меньшей мере один антенный модуль, каждый из которых содержит четыре излучающих элемента, расположенных эквидистантно в одной плоскости по узлам квадратной сетки, и волноводный синфазный делитель мощности, в котором распространяется волна ТЕ о1. Делитель мощности состоит из трех идентичных Т-образных сочленений, расположенных в плоскости вектора Е, четыре выхода которого посредством отрезков прямоугольных волноводов, оси которых перпендикулярны плоскости вектора Е, соединены с излучающими элементами. Каждый излучающий элемент имеет две пластины с электропроводящей поверхностью, плотно прилегающие друг к другу. Первая пластина содержит выемку прямоугольной формы, выполненную в центральной части со стороны, обращенной к второй пластине, глубина h которой приблизительно равна толщине пластины. Центр О выемки размещен на продольной оси N-N отрезка прямоугольного волновода, большая сторона с выемки параллельна большей стороне а отрезка прямоугольного волновода, и в каждой выемке вдоль сторон большего размера в непосредственной близости от них выполнены четыре щели длиной приблизительно с = Л/2, центры которых лежат в вершинах квадрата со сторой f < Л.The inventive high-frequency flat antenna array for receiving / transmitting a linearly polarized wave contains at least one antenna module, each of which contains four radiating elements located equidistant in the same plane along the nodes of the square grid, and a waveguide common-mode power divider, in which TE wave o1. The power divider consists of three identical T-joints located in the plane of the vector E, the four outputs of which are connected to the radiating elements by segments of rectangular waveguides whose axes are perpendicular to the plane of the vector E. Each radiating element has two plates with an electrically conductive surface, tightly adjacent to each other. The first plate contains a recess of rectangular shape, made in the Central part from the side facing the second plate, the depth h of which is approximately equal to the thickness of the plate. The center O of the recess is located on the longitudinal axis NN of the segment of the rectangular waveguide, the larger side of the recess is parallel to the larger side a of the segment of the rectangular waveguide, and in each recess along the larger sides in the immediate vicinity there are four slots with a length of approximately c = L / 2, the centers of which lie at the vertices of a square with side f <L.
