Design of Compact Bandpass Quasi-Elliptic Microstrip Filters

Abstract: Аннотация. Микроволновые фильтры являются неотъемлемым базовым элементом генераторов, синтезаторов частот, приемо-передающих модулей антенных систем с электрическим сканированием. Актуальной задачей остается разработка миниатюрных и технологичных микроволновых фильтров с повышенными требованиями к форме амплитудно-частотной характеристики, а также поиск новых методов для их анализа и расчета. Реализация алгоритмов для трехмерного расчета требует значительных временных ресурсов и представляет достаточно сложную… Show more

“…In this paper, we consider the application of the recursive method for coupling matrix synthesizing [6], as well as the electromagnetic modeling of coupled coaxial resonators in the MCBs to obtain the face topology of a quasi-elliptic band pass filter (QEF) [7,8] with a controlled and adjustable attenuation pole position, which significantly increases variety of implemented frequency response forms. The proposed new topology was tested using an example of a fourth-order filter with a relative passband of 10% with two attenuation poles on an MCB with a relative permittivity of 40.…”
