PACS number: 84.40.Ba Purpose: The question of the influence of modes of excitation of disk monopole antennas of microstrip topology on the antenna general properties is considered. The purpose of work consists in determination of the optimum method of antenna excitation for increasing the antenna matching level with the external microwave chains and its influence on the antenna energy characteristics.Design/methodology/approach: The modeling of antenna general properties is made by using the finite element method (FEM). The modeling is carried out within the model of a half-open resonator formed by the two metal surfaces (a grounded base and just a strip conductor), on which the condition of electric wall is fulfilled, and also by the cylindrical surface on which the condition of magnetic wall is fulfilled. In modeling, usually the thin substrate h<<λres is assumed, where h is a substrate thickness, λres being the resonance wave-length in a resonator. For such an assumption we may affirm that the vector of an electric field in a resonator will not have variations along the coordinate being perpendicular to the structure plane, and in the resonator, the prevailing types of oscillations will be oscillations E mn0 (TM mn0 ). In modeling, special attention has been paid to the mutual coupling of just a disk resonator and the resonator formed by a coaxial line segment. Findings: The information on the influence of the mode of excitation of disk monopole antenna with microstrip topology on the antenna general properties: spectral characteristics, degree of antenna matching with external chains, and energy characteristics with variation of substrate dielectric constant values is obtained.Conclusions: The data obtained testify that the monopole disk microstrip resonators with the complex-composite topology of radiators can provide a high level of integral characteristics and form the radiated fields with the required characteristics.Key words: disk microstrip resonator, slot radiator, mode of excitation, matching, directivity diagram Manuscript submitted 17.05.2018Radio phys. radio astron. 2018, 23(2): 128-136REFERENCES1.

PACS number: 84.40.Ba Предмет и цель работы: Рассматривается вопрос о влиянии способов возбуждения дисковой монопольной антенны микрополосковой топологии на основные характеристики антенны. Цель работы состоит в определении оптимального способа возбуждения антенны для повышения уровня согласования антенны с внешними СВЧ цепями и его влияния на энергетические характеристики антенны.Методы и методология: Моделирование основных характеристик антенны осуществлено с использованием метода конечных элементов (FEM). Моделирование проведено в рамках модели полуоткрытого резонатора, образованного двумя металлическими поверхностями (заземленное основание и собственно полосковый проводник), на которых выполняется условие электрической стенки, и цилиндрической поверхностью, на которой выполняется условие магнитной стенки. При моделировании обычно вводят предположение тонкой подложки h<<λres , где h - толщина подложки λres - резонансная длина волны в резонаторе. При такого рода предположении можно утверждать, что вектор электрического поля в резонаторе не будет иметь вариаций вдоль координаты, перпендикулярной плоскости структуры, а в резонаторе превалирующими типами колебаний будут колебания E mn0 (TM mn0 ). При моделировании особое внимание уделено взаимному влиянию собственно дискового резонатора и резонатора, образованного отрезком коаксиальной линии.Результаты: Получены данные о влиянии способа возбуждения дисковой монопольной антенны с микрополосковой топологией на основные характеристики антенны: спектральные характеристики, степень согласования антенны с внешними цепями и энергетические характеристики при вариации значений относительной диэлектрической проницаемости подложки.Заключение: Полученные данные свидетельствуют о том, что монопольные дисковые микрополосковые резонаторы со сложнокомпозиционной топологией излучателей могут обеспечивать высокий уровень интегральных характеристик и формировать излучаемые поля с требуемыми характеристиками.Ключевые слова: дисковый микрополосковый резонатор, щелевой излучатель, способ возбуждения, согласование, диаграмма направленностиСтатья поступила в редакцию 17.05.2018Radio phys. radio astron. 2018, 23(2): 128-136СПИСОК ЛИТЕРАТУРЫ1.

PACS number: 84.40.Ba Предмет і мета роботи: Розглядається питання про вплив способів збудження дискової монопольної антени мікросмужкової топології на основні характеристики антени. Мета роботи полягає у визначенні оптимального способу збудження антени для підвищення рівня узгодження антени із зовнішніми НВЧ ланцюгами і його впливу на енергетичні характеристики антени.Методи і методологія: Моделювання основних характеристик антени здійснене з використанням методу кінцевих елементів (FEM). Моделювання виконано в рамках моделі напіввідкритого резонатора, утвореного двома металевими поверхнями (заземлена основа та власне смужковий провідник), на яких виконується умова електричної стінки, та циліндричною поверхнею, на якій виконується умова магнітної стінки. При моделюванні зазвичай вводять припущення тонкої підкладки h<<λres , де h - товщина підкладки, λres - резонансна довжина хвилі в резонаторі. За таким припущенням можна стверджувати, що вектор електричного поля в резонаторі не матиме варіацій уздовж координати, перпендикулярної площині структури, а в резонаторі переважаючими типами коливань будуть коливання E mn0 (TM mn0 ). При моделюванні особливої уваги приділено взаємному впливу власне дискового резонатора і резонатора, утвореного відрізком коаксіальної лінії.Результати: Отримано дані про вплив способу збудження дискової монопольної антени з мікросмужковою топологією на основні характеристики антени: спектральні характеристики, міра узгодження антени із зовнішніми ланцюгами і енергетичні характеристики при варіації значень відносної діелектричної проникності підкладки.Висновок: Отримані дані свідчать про те, що монопольні дискові мікросмужкові резонатори із складнокомпозиційною топологією випромінювачів можуть забезпечувати високий рівень інтегральних характеристик і формувати випромінювані поля з необхідними характеристиками.Ключові слова: дисковий мікросмужковий резонатор, щілинний випромінювач, спосіб збудження, узгодження, діаграма спрямованості Стаття надійшла до редакції 17.05.2018Radio phys. radio astron. 2018, 23(2): 128-136СПИСОК ЛІТЕРАТУРИ1.
