    • The present invention provides a wideband frequency tunable ring resonator, wherein, comprises a closed λg/2 transmission line and two variable capacitors with tunable capacitance, the λg/2 transmission line is axisymmetric around a central line, first ends of the two variable capacitors are respectively connected to two intersection points of the λg/2 transmission line and the central line, the second ends of the two variable capacitors are respectively grounded. By implementing the technical solution of present invention, following technical effects are obtained. The fundamental resonant frequency (ffund) can be shifted up and down by controlling the respective values of the two loading capacitors, resulting in a bi-directional tuning of ffund. As a result, the tuning range of this invention can be approximately doubled as compared with the conventional tunable ring resonator.
    • 本发明提供一种宽带频率可调环形谐振器,其中包括一个闭合的λg/ 2传输线和两个具有可调电容的可变电容器,λg/ 2传输线围绕中心线是轴对称的,两个可变电容器的第一端 分别连接到λg/ 2传输线和中心线的两个交点,两个可变电容器的第二端分别接地。 通过实施本发明的技术方案,获得以下技术效果。 通过控制两个负载电容器的相应值,基本谐振频率(ffund)可以上下移动,从而导致ffund的双向调谐。 结果,与传统的可调环谐振器相比,本发明的调谐范围可以大致加倍。
