Problems solved by technology

In devices such as microstrip structures, dielectric resonators, and dielectric oscillators, because the electromagnetic field energy in these devices is concentrated in the device, the general tuning screw has little influence on the electromagnetic field, and the tuning effect is very poor.

Embodiment 1

[0035] Such as figure 1 , 2 As shown, a resonator tuning structure, including a metal cavity 1, and a tuning support body 2 extending from the metal cavity 1 into the metal cavity 1, and a tuning support body 2 extending into the metal cavity 1 The tuning dielectric body 3 at one end; it also includes a dielectric substrate 8 connected to the inner wall of the metal cavity 1, and a conductor strip 9 and a resonant cavity 7 connected to the dielectric substrate 8, and the tuning dielectric body 3 is located above the resonant cavity 7 . The tuning support body 2 is a columnar structure; the interface between the tuning medium body 3 and the tuning support body 2 is a plane. A thin metal sheet 4 is also arranged between the tuning medium body 3 and the tuning support body 2, and the interface between the tuning medium body 3, the thin metal sheet 4, and the tuning support body 2 is a plane parallel to each other; the tuning medium body 3 A thin metal sheet 4 is also provided ...

Embodiment 2

[0045] Such as image 3 , 4 As shown, the difference between Embodiment 1 of this implementation example lies in:

[0046] The resonant cavity 7 is a thin metal sheet.

[0047] Here we give an example implementation of a two-resonator tuning structure. The implementation of the present invention is not limited. For example, it is possible to decide whether to use a columnar metal platform 5 and a thin metal sheet 4 on the tuning structure according to the actual situation, a fixing device 6 of various structures, and a resonant cavity 7 of various materials and a conductor strip 9 of different structures can be used. . The resonant cavity tuning structure can also be used as a part to form other filter devices and microwave components.

Abstract

The invention discloses a resonator tuning structure, which comprises at least one metal cavity, a conductor belt, a medium substrate, a support body and a medium body, wherein the support body extends into the metal cavity from the outer side of the metal cavity; the medium body is arranged at the top end, which extends into the metal cavity, of the support body. The resonator tuning structure disclosed by the invention has the characteristics of simpleness in processing, flexible structure, convenience in use and sensitive tuning, and can be widely used for electronic systems of each microwave waveband, especially for the military and civil fields, such as radars, missile guidance and communication.

Description

technical field [0001] The invention relates to a resonator tuning structure, in particular to a dielectric resonator tuning structure for adjusting the characteristics of microwave devices. Background technique [0002] Tuning screws are usually used when tuning microwave devices. However, the tuning sensitivity of ordinary tuning screws is limited, and the gap between the tuning screw and the tuning structure of the dielectric resonator is often very small, which increases the difficulty of tuning, and this situation will also bring stability problems. . In devices such as microstrip structures, dielectric resonators, and dielectric oscillators, because the energy of the electromagnetic field in these devices is concentrated in the device, the general tuning screw has little influence on the electromagnetic field, and the tuning effect is very poor. Contents of the invention [0003] The main advantage of the present invention is that the electromagnetic field distribu...
