Modified Adaptive Prototype Inclusive of the External Couplings for the Design of Coaxial Filters.

The filter prototype of side-coupled coaxial filters, which we recently proposed, has been modified to suit an ar- rangement in which the coupling apertures are placed on the side opposite the coaxial end gaps. In this situation, the modified prototype fits the physical counterpart better, resulting in a fur- ther design simplification. In addition, the feeds have also been modeled and included into the prototype, thus enhancing the correspondence between the prototype and physical structure. A practical design, concerning a WIMAX application, shows the reliability of this solution. [ABSTRACT FROM AUTHOR]
