Abstract

The utility model discloses a novel microwave resonator. The novel microwave resonator comprises a metal shell, wherein the metal shell comprises an inner surface and can limit a resonant cavity, the lower end face at the bottom of the metal shell is provided with a round groove, the sidewall of the metal shell is provided with a ring-shaped cavity along the external edge of the round groove from bottom to top, the center of the round groove is provided with a through hole communicated with the inner surface of the metal shell, the lower end of the section of the through hole is cylindrical while the upper end thereof is trapezoidal, and a metal conducting plate is fixedly mounted in the round groove. The novel microwave resonator enhances the electrical performance of products, improves power, mutually mediates loss, simultaneously reduces product dead weight, and saves material cost and transportation cost.

Description

The novel microwave resonator

Technical field

The utility model relates generally to the resonator field, relates in particular to a kind of novel microwave resonator.

Background technology

At present, common microwave resonator has following weak point on the market:

1) power of Electric Field Distribution is low;

2) contact area on product and ground is little;

3) product itself from great, simultaneously also be unfavorable for contacting with ground;

4) be not easy to frequency trim.

The utility model content

The utility model purpose is exactly in order to remedy the defective of prior art, a kind of novel microwave resonator to be provided.

The utility model is achieved through the following technical solutions:

The novel microwave resonator, it is characterized in that: include metal shell, described metal shell has an inner surface and can limit resonant cavity, have a circular groove on the lower surface of described metal shell bottom, have an annular housing along the outer edge of circular groove is bottom-up on the sidewall of described metal shell, the center of circular groove has a through hole that communicates with the inner surface of metal shell, the lower end of through hole is cylindrical, the upper end is trapezoidal, is installed with the circular metal conductive plate in the circular groove.

The lower end embeds cylindrical dielectric parts in the described through hole, and the upper end embeds a trapezoidal briquetting.

Be processed into chamfering between the upper surface of described metal shell and the sidewall.

The utlity model has following advantage:

Adopt the utility model structure, just can form single resonant rod, thereby increase the reliability of product, strengthened the product electric property, improved power, intermodulation and loss have reduced the product deadweight simultaneously, have saved material cost and cost of transportation.

Embodiment

As shown in Figure 1, 2, the novel microwave resonator, include metal shell 1, metal shell 1 has an inner surface and can limit resonant cavity 2, have a circular groove 3 on the lower surface of metal shell 1 bottom, have an annular housing 4 along the outer edge of circular groove 3 is bottom-up on the sidewall of metal shell 1, the center of circular groove 3 has a through hole 5 that communicates with the inner surface of metal shell 1, the lower end, cross section of through hole 5 is cylindrical, the upper end is trapezoidal, is installed with circular metal conductive plate 6 in the circular groove 3.

Through hole 5 interior lower ends are used for embedding cylindrical dielectric parts, and the upper end is used for embedding a trapezoidal briquetting.

Be processed into chamfering 7 between the upper surface of metal shell 1 and the sidewall.

As shown in Figure 1,7 places of the present utility model add the man-hour chamfering and have reduced Electric Field Distribution and improve power; 3 places are provided with a groove, have reduced the product contact area, have strengthened the contact on ground; 4 places are that hollow minimizing deadweight also is conducive to the ground contact simultaneously; 2 places are that hollow is convenient to frequency trim.

Use the utility model that resonating device is perfectly merged in the cavity that electromagnetic field distributes, strengthened the performance of product, improve the loss of product, power, intermodulation improves a lot for the product of the high-power high intermodulation of large volume, has alleviated simultaneously deadweight and has reduced material cost and cost of transportation.
