Abstract: Группа изобретений относится к области антенной техники, а более конкретно к антеннам на основе технологии многослойных печатных плат, и может быть использована при проектировании и изготовлении антенных фазированных решеток с электрически управляемой диаграммой направленности, формирующих луч с круговой поляризацией. Многослойный печатный излучатель по первому варианту выполнен в виде многослойной платы, содержащей шесть слоев металлизации, разделенных слоями диэлектрика. Первый слой металлизации включает в себя пассивные элементы четырех излучающих элементов. Второй слой металлизации включает в себя возбудители излучающих элементов, каждый из которых расположен под соответствующим пассивным элементом, центр каждого из которых, в свою очередь, электрически соединен с центром соответствующего возбудителя. Каждый из упомянутых возбудителей и пассивных элементов выполнен в виде квадрата с отсеченными противолежащими углами. Упомянутые возбудители и пассивные элементы расположены таким образом, что центр симметрии каждого из них находится в соответствующей вершине квадрата, а продольная ось симметрии всех возбудителей и соответствующих пассивных элементов параллельна или перпендикулярна проходящей через возбудителя диагонали квадрата. Третий слой металлизации включает в себя четыре щели, каждая из которых расположена под соответствующим возбудителем и выполнена таким образом, что имеет две перпендикулярные друг другу оси симметрии, продольные оси симметрии которых образуют угол 45 градусов с продольной осью симметрии соответствующего возбудителя. Четвертый слой металлизации включает в себя четыре полосковые линии, каждая из которых электромагнитно связана с соответствующей щелью и с четырьмя полосковыми линиями шестого металлизированного слоя, которые выполнены с возможностью соединения с входом или выходом излучающего элемента. Упомянутые возбудители и пассивные элементы расположены в окнах, в которых слой металлизации отсутствует, а слои металлизации вокруг них электрически соединены металлизированными отверстиями, расположенными вокруг каждого излучающего элемента, друг с другом, с третьим слоем металлизации и пятым слоем металлизации, являющимися заземляющими. Многослойный печатный излучатель по второму варианту отличатся тем, что содержит четыре пары щелей, при этом одна щель из каждой пары электромагнитно соединена (посредством полосковых линий) с согласованной нагрузкой. При использовании группы изобретений достигается технический результат, состоящий в упрощении конструкции излучателя и технологии изготовления без ухудшения (а в случае второго варианта реализации изобретения с существенным улучшением) радиотехнических характеристик. 2 н.п. ф-лы, 27 ил., 1 табл.
