Özet:

 This paper presents a wide-band transmission line model for defected ground structures DGSs based on a mode-conversion between microstrip- and slot-lines. The defects on the ground plane are modeled as short- or open-ended transmission lines TLs with slot-line characteristics. The transition between microstrip line and ground defect is modeled with interdependent voltage and current sources, of which the first one is placed in series with the microstrip line, and the latter in-shunt with the slot lines, respectively. A complete set of geometry-dependent analytical expressions for the ABCD parameter of a two-port microstrip line crossing over the defected structure is provided. Therefore, the proposed model can be readily integrated into computer-aided design programs. The models accuracy is verified in various defect shapes by comparing its results with those from HFSS simulations and measurements.

 Bu makale, kusurlu toprak yapıları DGSler için mikroşerit ve yarık hatlar arasında mod dönüşümüne dayanan bir geniş bantlı iletim hattı modeli sunmaktadır. Toprak düzlemindeki kusurlar, yarıklı hat slot-line özelliklerine sahip kısa veya açık devre ile sonlandırılmış iletim hatları İHler olarak modellenmiştir. Mikroşerit hat ile topraklama kusuru arasındaki geçiş, sırasıyla ilki mikroşerit hat ile seri ve ikincisi yarık hatlarla şönt olarak yerleştirilmiş birbirine bağlı gerilim ve akım kaynakları ile modellenmiştir. Önerilen modelde kusurlu yapı üzerinden geçen iki portlu bir mikroşerit hattın tüm ABCD parametresi geometriye bağlı bir analitik ifadeler seti sağlanmaktadır. Bu da, önerilen modelin bilgisayar destekli tasarım programlarına kolayca entegre edilebilmesine olanak sağlamaktadır. Modelin doğruluğu, model sonuçlarının HFSS simülasyonları ve ölçümlerinden alınan sonuçlarla karşılaştırılarak çeşitli kusur şekilleri için doğrulanmıştır.
