It was cut in the vertical direction, or the end surface or outer peripheral surface of the cylinder was polished.

なるという問題点があった。However, when the above-described method of adjusting the resonance frequency is used, the volume of the body of the resonant element of the dielectric becomes small, so that the unloaded Q (Q 0 ) of the dielectric resonator device concerned is reduced. However, there is a problem that the desired steep bandpass filter characteristic cannot be obtained. Further, when the shape of the dielectric is changed, such as when the length of the dielectric in the axial direction is changed, it may be necessary to change the support base or the support method for supporting the dielectric in the shield case. Further, in order to obtain a desired resonance frequency by using the above-mentioned conventional method, the work is relatively complicated and requires a lot of work time, and the work cost becomes large, which causes the dielectric resonator device. However, there is a problem that the manufacturing cost of the product increases.

できる。As is apparent from FIG. 3, it can be seen that by increasing the length of the cut 11, the resonance frequency of the device shifts in the higher direction. This is because by forming the cut 11, a part of the lines of electric force that are concentrically formed on the cylindrical cross section of the dielectric 10 is cut when the device is excited, and the length of the cut 11 is cut. By increasing the amount of electric field lines to be cut,
The effective permittivity of the dielectric resonant element is reduced, thereby increasing the resonant frequency of the device. That is, by forming the cuts 11 in the radial direction of the cylinder, it is possible to change the effective permittivity of the resonant element of the dielectric, and thereby change the resonant frequency of the device.

Become. Further, since the axial length of the dielectric 10 is not cut or the end face of the cylinder or the outer peripheral portion of the cylinder is not polished, the volume of the dielectric hardly changes, and therefore the unloaded Q of the dielectric resonator device decreases. There is nothing to do.

Create 5 dielectric rings 21 to 25, 1 of which
Sixteen cuts 12 having a rectangular cross section are formed at the edge of the outer circumference of the cylinder of each dielectric ring 21 in the radial direction from the center of the cylinder. Then, the dielectric ring 21 having the cut 12 is coaxially bonded and formed on the four dielectric rings 22 to 25 which are coaxially bonded to each other. The dielectric resonant element thus formed is placed in the central portion of the shield case 2 of, for example, a metallic cylindrical cavity, as in the first embodiment. In any of the embodiments, the shield case 2 may be formed by forming a shield electrode film on a ceramic dielectric.

It can be seen that the resonance frequency can be changed by changing the position of the dielectric ring 21 having the axis in the axial direction. This is because, as shown in FIG. 6, the electric field strength at a position on a line P that is separated from the axis Q of the dielectric body by a predetermined distance d 1 and that is parallel to the axis Q and that passes through the inside of the cylinder is Since it becomes maximum at the central portion in the axial direction, the amount of decrease in the effective permittivity of the dielectric material when the cut 12 is formed at the central portion becomes maximum, and the deviation Δf of the resonance frequency becomes maximum.

ないという利点がある。As described above in detail, according to the method of adjusting the resonance frequency of the dielectric resonator device according to the present invention, the resonance frequency of the dielectric resonator device in which the dielectric is placed in the shield case. In the adjusting method of (1), the effective permittivity of the dielectric is changed by forming a cut in the dielectric so as to intersect with an electric force line generated when the dielectric is excited, thereby changing the effective dielectric constant of the device. The resonance frequency can be changed. Therefore, the work is simpler than that of the conventional example, and the desired resonance frequency can be easily adjusted by changing the number or length of the cuts. In addition, the volume of the above-mentioned dielectric hardly changes,
Therefore, there is an advantage that the unloaded Q of the dielectric resonator device does not decrease.
