Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Before introducing the present invention, first introduce the working principle of the dielectric resonator:

[0022] like Image 6 As shown, when the electromagnetic wave enters the low dielectric constant medium from the high dielectric constant medium, it will be reflected and refracted on the interface. When the incident angle is greater than or equal to the critical angle, the electromagnetic wave will be totally reflected. The higher the dielectric constant of the medium, the smaller the critical angle, and the more perfect the total reflection phenomenon. A magnetic wall is formed on...

Abstract

The invention provides a dielectric resonator tuning structure and a dielectric resonator tuning method. The structure comprises a cavity, a dielectric resonance pole, a tuning component, a tuning cover plate, a nut and bolts, wherein the dielectric resonance pole is fixedly arranged at the bottom of the cavity; the tuning component is arranged on the tuning cover plate; the nut is arranged at the top end of the tuning component, and is used for locking the tuning component after tuning is finished; and the tuning cover plate is fixed on the cavity through the bolts. The tuning component is moved up and down by rotating a plastic screw on the tuning component to change a distance between a metal sheet and the dielectric resonance pole, so that required resonance frequency can be obtained by properly regulating the distance in a small space, and specifically, frequency is increased if the plastic screw is screwed in, and is decreased if the plastic screw is screwed out; and in addition, the production cost is decreased, the production efficiency of the product is improved, and the market share is increased.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a dielectric resonator tuning structure and tuning method. Background technique [0002] With the rapid development of mobile communication services, the frequency resources of communication systems are becoming increasingly tight. How to control and reduce mutual interference between communication systems and reduce system construction costs is very critical. [0003] The size and weight of the frequency selection device filter in the communication system are closely related to the system construction cost, while the performance of drop loss and suppression directly affects the quality of the system performance. Therefore, a dielectric filter with small size, light weight, high Q value, low in-band insertion loss and high out-of-band rejection is one of the good solutions to this problem. However, compared with ordinary metal resonators, dielectric resonators are more di...
