Исследование коммутируемого волноводно-щелевого излучтеля

Abstract

Тема выпускной квалификационной работы: «Исследование коммутируемого волноводно-щелевого излучателя». Исследования в данной работе направлены на изучение характеристик и разработку волноводно-щелевой антенной решетки на основе низкопрофильной SIW (волновод, интегрированный в подложку) структуры с четырьмя щелями и возможностью электронного управления лучом. В первой главе рассмотрены основные теоретические знания, используемые в работе. Представлен обзор достижений описанных в ряде статей и патентов по темам: перестраиваемая диаграмма направленности (ДН) щелевых антенн, волновод на основе SIW-структуры, щелевые антенны на основе волновода SIW-структуры. Вторая глава включает в себя исследование электродинамических характеристик антенны на основе волновода SIW-структуры. Эта глава включает описание изготовленного мною экспериментального образца антенны. Предлагается способ нахождения сопротивления излучению щели в исследуемой SIW структуре. Также производится численный (с помощью программы Ansys HFSS) и аналитический расчет параметров ДН, а также сравнение теоретических и экспериментальных результатов.

Topic of the final qualifying work: "Research of a switched waveguide-slit emitter". The research in this paper is aimed at studying the characteristics and development of a waveguide-slot antenna array based on a low-profile SIW (waveguide integrated into the substrate) structure with four slits and the ability to electronically control the beam. The first Chapter describes the main theoretical knowledge used in the work. An overview of the achievements described in a number of articles and patents on the topics: tunable directional pattern (DN) of slotted antennas, waveguide based on SIW structure, slotted antennas based on a SIW waveguide structure. The second Chapter includes a study of the electrodynamic characteristics of an antenna based on a SIW waveguide structure. This Chapter includes a description of an experimental antenna sample that I made. A method for finding the gap radiation resistance in the SIW structure under study is proposed. Numerical (using the Ansys HFSS program) and analytical calculation of DN parameters is also performed, as well as comparison of theoretical and experimental results.
