Other methods have also been used. However, most of the analysis exists for analysis of single resonators. However, for practical dielectric resonators (when more than one loaded cavity is used) there may be apertures coupling one resonator to the other. In addition there may be probes coupling one resonator to the other to carry out response shaping or even cancel out the effects of the higher order modes. Also, probes may be utilized to couple energy into and out of the resonators. The high dielectric constant resonator is generally placed on top of a low dielectric constant material for support. Hence an effective analysis modeling is necessary which will predict the actual experimental data accurately if the appropriate material properties are correctly specified for coupled multiple dielectric resonators. This includes analysis of dielectric resonators with aperture couplings along with probe feeds.","PeriodicalId":339267,"journal":{"name":"1999 IEEE MTT-S International Microwave Symposium Digest (Cat.

This paper introduces a new concept within the coupled-integral-equations-technique (CIET) which takes into account all edge conditions simultaneously and, therefore, permits the analysis and optimization of such filter components in a timely fashion. A 12.3 GHz four-pole dual-mode filter in rectangular waveguide is chosen as design example. Comparison with HP's HFSS shows good agreement, whereas the mode-matching technique (MMT) did not converge with up to 600 modes. The CIET routine converges with up to 23 edge-conditioned vector basis functions and up to 1750 modal summation terms. Due to its speed, the new approach can also be used for a Monte-Carlo-based tolerance analysis which shows a manufacturing accuracy of 0.02 mm for this critical dual-mode filter example.","PeriodicalId":339267,"journal":{"name":"1999 IEEE MTT-S International Microwave Symposium Digest (Cat.
