Title:
DIELECTRIC RESONATOR OSCILLATOR
Document Type and Number:
WIPO Patent Application WO/2018/014780
Kind Code:
A1
Abstract:
A dielectric resonator oscillator, comprising a housing (100), a dielectric resonator (200) and a microstrip line (300), wherein the dielectric resonator (200) and the microstrip line (300) are mounted inside the housing (100), and the dielectric resonator (200) is located at one side of the microstrip line (300) and is electromagnetically coupled to the microstrip line (300). The dielectric resonator oscillator further comprises a first circuit board (400) and a support structure (500), wherein the microstrip line (300) is arranged on the first circuit board (400); the support structure (500) is connected between the first circuit board (400) and the housing (100), and the support structure (500) and the dielectric resonator (200) are mounted at the same side in the housing (100); and the first circuit board (400), the support structure (500) and the housing (100) together constitute a cavity (800), and inner and outer spaces of the cavity (800) are in communication with each other. Therefore, electromagnetic waves below the microstrip line (300) can be coupled to the dielectric resonator (200) via the cavity (800), thereby decreasing the amount of electromagnetic waves absorbed by the housing (100), reducing the loss of electromagnetic wave energy and improving a Q value of the dielectric resonator oscillator.
