摘要

考虑了基于两个开路桩的谐振器的频率阻抗特性和传输响应特性。这种谐振器的优点是频率响应的斜率很高，并且在谐振频率附近存在两个零。当从谐振器的谐振频率失谐时，阻带中明显的选择性恶化限制了它的使用。提出并分析了基于传输线截面的解决方案，以改善阻带的抑制，提高谐振器的质量因数。

Selectivity Increasing of Resonator on Open-Circuited Stubs

The features of the frequency impedance characteristic, as well as the transmission response of a resonator based on two open-circuited stubs, are considered. The advantage of such a resonator is the high steep slope of the frequency response and the presence of two zeros near the resonant frequency. A noticeable selectivity deterioration in the stop bands when detuning from the resonant frequency of a resonator limits its use. Solutions on the basis of transmission line sections, allowing to improve the suppression in the stop-bands and increase the quality factor of such resonator, are proposed and analyzed.
