In this research, a high Q resonator was presented to realize a band pass filter having a low-loss characteristic. In the first year, a resonator design method using a rigorous analysis of the resonance electro-magnetic fields has been developed. The multi stage narrow band pass filters have been designed with these resonators and the low-loss characteristics of about 1 dB insertion loss at 60 GHz. In the second year, the filter circuit arrangement to improve the spurious characteristic has been investigated. As a result, a spurious free response for the designed band pass filter was obtained over the wide frequency rang of several tens GHz. Research results are summarized as follows ;(1)An optimized resonator design procedure considering the high Q characteristic and the higher order mode suppression is shown with the several design charts.(2)The coupling resonance characteristics of the coupled resonators are analyzed and calculated to obtain the basic data for filter designs.(3)It is found that the millimeter-wave narrow bandpass filter which consists of the designed high Q dielectric disk resonators can have a low-loss characteristic.(4)It is found that the spurious characteristic of the filters can be improved dramatically by optimizing the resonator arrangement.

在本研究中，高Q值谐振器被提出来实现具有低损耗特性的带通滤波器。在第一年，谐振器的设计方法，使用谐振电磁场的严格分析已经开发出来。用这些谐振器设计了多级窄带通滤波器，在60 GHz时具有约1 dB的插入损耗的低损耗特性。第二年，研究了改善寄生特性的滤波器电路布置。结果表明，所设计的带通滤波器在几十GHz的宽频率范围内均获得了无杂散响应。主要研究结果如下：（1）给出了考虑高Q值特性和高阶模抑制的谐振腔优化设计方法，并给出了设计图表。（2）对耦合谐振器的耦合谐振特性进行了分析和计算，为滤波器的设计提供了基础数据。(3)It结果表明，由所设计的高Q介质圆盘谐振器构成的毫米波窄带滤波器具有低损耗特性。(4)It发现通过优化谐振器结构可以显著改善滤波器的寄生特性。
