Багатоелементні антени на циліндричних діелектричних резонаторах і смужкових лініях у випадку їх ортогональної взаємної орієнтації

Abstract

The design of a singleelement antenna, where cylindrical dielectric resonator, which is located orthogonally relative to feeding microstrip line, is used as radiating element, is described. There have been performed the numerical analysis of it and defined the functions approximating its directivity patterns. The schemes of feeding arrays of dielectric resonators for narrowing directivity patterns in Eand H-planes are proposed. The numerical analysis of antenna array 4x4 elements was performed and comparison of gained directivity patterns with ones calculated from analytical expressions was made. The graph of dependence of width of the main lobe in Eand H-planes for arrays of dielectric resonators versus the number of resonators in corresponding planes was plotted.

Описана конструкция одноэлементной антенны, у которой излучающим элементом является цилиндрический диэлектрический резонатор, размещенный ортогонально относительно питающей несимметричной полосковой линии. Проведено ее численное моделирование и определены функции, аппроксимирующие ее диаграммы направленности. Предложены схемы питания решеток диэлектрических резонаторов для сужения диаграммы направленности в Еи Н-плоскостях. Проведено численное моделирование решетки 4х4 элемента и выполнено сопоставление полученных диаграмм направленности с рассчитанными аналитически. Построен график зависимости ширины главного лепестка диаграммы направленности решеток и электрических резонаторов в Еи Н-плоскостях от количества резонаторов в соответствующих плоскостях.
