改变覆盖层参数对微波介质谐振器谐振特性的影响

Pesonant Frequency of a Dielectric Resonator with Over-Layer

讨论了一种调节微波介质谐振器谐振频率的新方法，通过改变该结构中介质谐振器顶端介质覆盖层的厚度，或者置换具有不同介电常数的介质覆盖层，均可实现谐振频率的微调，本文应用开波导法分析和计算了介质覆盖层参数的改变对微波介质谐振器谐振特性的影响，并将计算结果与实验数据进行比较。

A new dielectric resonator construction is described. This resonator consists of a high dielectric constant resonator element mounted on a lowloss dielectric mount, a low dielectric disk set on the Resonator element. The resonant frequency tuning is made by varying the thick of dielectric constant of the dielectric disk. The TE-{01} mode resonant frequencies are analyzed through dielectric wave guide mode application. Less than 3 percent analytical error is presented in comparison with the experimental data for practical resonator.
