Modeling and optimization of microwave ring resonator filters using CST software

摘要: The thesis reports on modeling two types of bandpass microwave filters that use dielectric resonator for filtering the signal. instance is done using a commercial CST software package introduces and outlines approach filters. Then tested meshing properties simulation results. first model ring loaded substrate excited by microstrip lines. second has rings in metal box which filled with foam. The impact different mesh sizes investigated convergence S-parameters, particular their characteristics at center frequency. Many simulations have been to find out relationship between physical parameters, such as radius outer ring, S-parameters. also used optimize changing critical parameters. patterns e-field h-field are compared analyzed modify structure filter. newly developed CST's Perfect Boundary Approximation (PBA) FPBA solver prove quality. Based data, guess proposed revise result get better accuracy.
