Reflectance data model with mixed lumped and distributed elements for wireless communication systems Authors:Yarman, Binboǧa Sıddık; Şengül, Metin Y.; Kılınç, Ali; Aksen, Ahmet
Publisher and Date:(2005)In this paper, a new method is presented to model the given reflectance data obtained from a "passive one-port physical device", as a lossless two port consists of lumped and distributed elements. Basis of the new method rests on the interpolation of the given data as a realizable bounded-real (BR) reflection function in two variables. The desired circuit model is then obtained as the result of the synthesis of this function in two kinds of elements; namely, distributed and lumped circuit elements. ...
A single matching network design for a dual band PIFA antenna via simplified real frequency technique Authors:Lindberg, Peter; Şengül, Metin Y.; Çimen, Ebru Gürsu; Yarman, Binboǧa Sıddık; Rydberg, Anders; Aksen, Ahmet
Publisher and Date:(2006)In this paper, the matched performance of a dual band PIFA antenna is reported. The return loss of the antenna has been optimized over the popular commercial wireless communication bands of 824-960 MHz and 1710-1990 MHz using only one matching network. The network was synthesized using the Simplified Real Frequency Technique, which yields an "easy to implement circuit topology" and realizable component values. With the implemented matching network, a simultaneous measured bandwidth enhancement of ...
