Embodiment Construction

[0026] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0027] It should be noted that when an element is referred to as being "fixed to", "installed on", "fixed on" or "installed on" another element, it can be directly on the other element or there may be a central element . When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. Further, when one element is "electrically connected" to another element, the two can be connected either detachably or non-detachably, such as welding, electrical b...

Abstract

The invention discloses a dielectric waveguide filter and an input and output structure thereof. The input and output structure of the dielectric waveguide filter comprises a dielectric body and a substrate; a first metal layer serving as an electric wall and a short circuit layer are arranged on the outer wall of the dielectric body; the short circuit layer comprises a connecting end electricallyconnected with the first metal layer, and a short circuit line which is insulated from the first metal layer; the substrate comprises a first surface and a second surface opposite to the first surface; the second surface is provided with a grounding layer and an open circuit line which is insulated from the grounding layer; and the open circuit line is electrically connected with the short circuit line, and an input and output electrode is formed. According to the input and output structure, the input and output electrode is formed on the substrate; compared with the prior art, a coaxial connector and a cable are reduced, the cost is reduced, and the size is further reduced; and the dielectric waveguide filter utilizes the input and output structure, so that the size of the filter can befurther reduced, and the miniaturization development of a base station antenna is facilitated.

Description

Technical field [0001] The present invention relates to the technical field of communication equipment, in particular to a dielectric waveguide filter and its input and output structure. Background technique [0002] With the rapid development of communication systems entering the 5G era, miniaturization of components is the key to the development of its communication equipment. As a key component in wireless communications, waveguide filters will also develop in the direction of miniaturization. [0003] High-permittivity dielectric materials can be applied to waveguide devices to obtain dielectric waveguide filters. The dielectric waveguide filter improves the air-filled form of traditional waveguide filters into a form filled with high-permittivity dielectric materials. The dielectric material is formed after molding. In order to transmit signals and support the structure, the metal layer is attached to the surface of the dielectric material to form an electrical wall, which pla...
