Abstract :
In this paper, it is shown, that the quality factor of cavity resonators can be increased through proper arrangement of corner roundings. To overcome numerical uncertainties of the Q-factor calculation, parametric sweeps and polynomial curve fitting are applied. A corresponding analysis is performed for combline resonators and filters by introduction of a base rounding. As a result, the Q-factor is increased by 5%.
