环隙谐振器是新开发的微波谐振结构，其场配置介于集总和分布之间。典型的特征尺寸约为谐振波长的 1/10，典型的 Q 值在 1-4 GHz 频率范围内约为 1600-2000。提供了一系列不同尺寸谐振器的 Q 值和频率数据，并与理论值进行了比较。讨论了各种耦合和频率调谐技术，并报告了实验结果。介绍了该粘胶在微波滤波器和振荡器中的初步应用结果。结论是，环隙谐振器为低微波频率下的介电和表面声波谐振器提供了一种有用的设计替代方案。
Loop-gap resonators are newly developed microwave resonant structures with a field configuration that is intermediate between lumped and distributed. Typical characteristic dimensions are of the order of 1/10 of the resonant wavelength, and typical Q's are of the order of 1600-2000 in the frequency range of 1-4 GHz. Data are presented for Q's and frequencies for a series of resonators of various dimensions and compared with theory. Various coupling and frequency tuning techniques are discussed, and results of experiments are reported. Results of preliminary application of the stictire in microwave filters and oscillators are presented. Loop-gap resonators provide a useful design alternative, it is concluded, to dielectric and surface acoustic-wave resonators at low microwave frequencies.
