摘要： [Problem] There is provided a coaxial resonator having a high Q value in the first resonant mode and a wide resonance frequency gap between the first resonant mode and the second resonant mode, as well as a dielectric filter, a wireless communication module, and a wireless communication device employing the same.
[Solution] A coaxial resonator includes a dielectric block (10); a first inner conductor (13) disposed in an inner surface of a first through hole (11) which extends from a first main surface of the dielectric block to an opposite second main surface thereof, the first inner conductor (13) being connected to a reference potential at one side thereof ; and an outer conductor (15) disposed over side surfaces of the dielectric block (10), the outer conductor surrounding the first inner conductor (13), the outer conductor (15) being connected to the reference potential. There is a low-dielectric-constant portion in a location between the first inner conductor (13) and the outer conductor (15). The low-dielectric-constant portion surrounds a periphery of the first inner conductor (13) and is lower in dielectric constant than the dielectric block (10). A coaxial resonator having a high Q value in the first resonant mode and a wide resonance frequency gap between the first resonant mode and the second resonant mode can be obtained.摘要翻译： [问题]提供了一种具有在第一谐振模式高Q值和所述第一谐振模式和第二谐振模式之间的宽共振频率间隙，以及一个介质滤波器中，无线通信模块，和一个同轴谐振器 无线通信装置采用相同。 [解决方法]一种同轴谐振器包括一介质块（10）; 通孔（11）设置成第一内表面的第一内导体（13）从所述介电块的第一主表面上的相对的第二主表面上，其延伸到，第一内导体（13）被连接到一个 在其一侧参考电位; 和在设置在所述介质块（10）的侧表面上的外导体（15），围绕所述第一内部导体（13）的外导体，所述外部导体（15）被连接到参考电位。 有在第一内部导体（13）和外导体（15）之间的位置处的低介电常数部分。 低介电常数部分围绕所述第一内部导体（13）的周边，并且是在比电介质块（10）的介电常数低。 具有在所述第一谐振模式高Q值和所述第一谐振模式和第二谐振模式之间的宽共振频率间隙A的同轴谐振器能够得到。
