A novel microstrip triple wideband bandstop filter design by using adjacent direct coupled dual-mode resonators
Abstract
In this article, a novel triple wideband bandstop filter design is proposed with two adjacent microstrip square loop resonators (MSLR) having different edge lengths. Degenerate modes of the square loop resonators are induced by using direct coupling mechanism. Perturbation and loading elements are located on resonators and used to control reflection zeros between the second and third bands. Even odd mode analysis of a single direct coupled dual-mode resonator is also extracted to elucidate the filter topology. The proposed resonator structure is designed by using a full-wave EM simulator and three different filter responses are obtained from the designed resonator structure. One of the filters is fabricated and, it is observed that measured results are compatible with simulated results.

Bitişik direk kuplajlı çift-modlu rezonatörler kullanılarak yeni bir mikroşerit üç geniş bantlı bant tutan filtre tasarımı
Abstract
Bu çalışmada iki adet farklı kenar uzunluğuna sahip birbirlerine bitişik olan mikroşerit kare halka rezonatör kullanılarak yeni bir üç geniş bantlı bant tutan filtre tasarımı yapılmıştır. Kare halka rezonatörler direk kuplaj yöntemi ile beslenerek dejenere modlarının uyarılması sağlanmıştır. Tasarlanan rezonatörler üzerinde perturbasyon ve yükleme elemanları var olup, dejenere modların arasındaki kuplaj değişimi ile filtrenin ikinci ve üçüncü bandları arasındaki yansıma sıfırları kontrol edilebilmiştir. Önerilen filtre topolojisini desteklemek için direk kuplajlı tek bir kare halka rezonatörün tek-çift mod analizi yapılmıştır. Geliştirilen rezonatör yapısı bir tam dalga EM benzetim programı kullanılarak tasarlanmış ve bu yapıdan üç farklı filtre cevabı elde edilmiştir. Filtrelerden bir tanesi gerçekleştirilmiş olup, sonuçlar uyum içerisindedir
