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

[0034] Such as figure 1 , 2 as shown,

[0035] A planar circuit tuning structure, comprising a metal cavity 1, a tuning support body 2 protruding from the metal cavity 1 into the metal cavity 1, and a tuning support body 2 protruding into the metal cavity 1. The tuning dielectric body 3 also includes a dielectric substrate 8 connected to the inner wall of the metal cavity 1 and a metal conduction strip 7 connected to the dielectric substrate 8 ; the tuning dielectric body 3 is located above the metal conduction strip 7 .

[0036] In the present invention, the tuning medium body 3 is arranged at the end of the tuning support body 2 protruding into the metal cavity 1 . With the help of the function of the tuning dielectric body 3, its electromagnetic field distribution can be changed, thereby adjusting the characteristics of the microwave device. Generally, the wavelength of the electromagnetic wave in the air is relatively large. After adding the tuning medium 3, the transmi...

Abstract

The invention discloses a planar circuit tuning structure comprising a metal cavity, a tuning support body which extends into the metal cavity from outside, and a tuning dielectric body which is arranged on one end, which extends into the metal cavity, of the tuning support body; a dielectric substrate which is connected with the inner wall of the metal cavity and a metal conduction band which is connected with the dielectric substrate are also arranged; and the tuning dielectric body is arranged above the metal conduction band. The planar circuit tuning structure has the characteristics of simplicity in processing, flexible structure, convenience in use, flexibility in tuning and the like, and can be widely applied to electronic systems with various microwave bands, particularly radar, missile guidance, communication and other military and civilian fields.

Description

technical field [0001] The invention relates to a planar circuit tuning structure, in particular to a dielectric resonant cavity 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 fie...
