Broadband Decoupling and Matching of a Superdirective Two-Port Antenna Array
Volmer, Christian; Şengül, Metin Y.; Weber, Joern; Stephan, Ralf; Hein, Matthias A. (IEEE-INST Electrical Electronics Engineers Inc, 2008)Decoupling and matching networks may be used to improve the performance of compact antenna arrays where mutual radiator coupling has caused a degradation of the diversity capabilities. A popular network consists of a 180 ... -
Design of distributed-element RF filters via reflectance data modeling
Şengül, Metin Y.; Yarman, Sıddık Binboğa; Volmer, Christian; Hein, Matthias A. (Elsevier GMBH Urban & Fischer Verlag, 2008)A reflectance-based modeling method is presented to obtain the distributed-element counterpart of a lumped-element network which is described by measured or computed reflectance data at a set of frequencies. Numerical ...
