Optimalizace koaxiálních filtrů metodou Tuning-Space Mapping v CST / Optimizing coaxial filters by Tuning-Space Mapping in CST

Wolanský, David January 2010 (has links)
This thesis deals with optimization of coaxial cavity filters. It thoroughly describes optimization method Tuning – Space Mapping (TSM) in CST Studio. It focuses on the explanation of the fine and the coarse model and their mutual link. The whole algorithm is illustrated and tested on the third-order coaxial cavity filter working in the band of 880 – 960MHz. In order to check the function of TSM, the algorithm is applied on fourth-order filter, triplet filter and quadruplet filter. Another part of the thesis focuses on the automatization of the whole optimization procedure. Macros for automatic determination of calibration constants and automatic calibration process between the coarse and the fine model are proposed and programmed in CST. The complete optimization procedure is applied on optimization of seventh-order filter with two cross couplings.

Knihovna stavebních prvků koaxiálního filtru pro CST Microwave Studio / Library of building elements of coaxial filters for CST Microwave Studio

Vorek, Jiří January 2010 (has links)
This thesis deals with development of tool – macros which help to create coaxial cavity filters. It describes problematic design of complex structures at CST Studio Suite 2009. For this purpose macros supporting coarse and fine model to method Tuning – Space Mapping (TSM) was made. This means creating fine model at CST MWS and coarse model at CST DS.
