An LTCC microwave dielectric material, including the following components: a BaSiO+(1−a) (MgCaSrBa)WO+Ba—B—Si glass; wherein 0.4≤a≤0.8, 0≤x≤1, 0≤y≤1, 0≤z≤1. By adjusting the amounts of BaSiOand (MgCaSrBa)WO, the temperature coefficient of resonance frequency can be adjusted to nearly zero. The material is suitable for the fields of high-frequency communication and radiofrequency. Also disclosed is a method for preparing the LTCC microwave dielectric material.

LTCC microwave dielectric material and preparation method thereof

The invention relates to the technical field of a refrigerator or a wine refrigerator, and more particularly relates to a combined shelf structure. The combined shelf structure is arranged in a wine refrigerator. The combined shelf structure comprises at least two shelf bodies and at least two carrier bars. Connecting holes through which two carrier bars pass are respectively arranged at both ends of each shelf body. Either the top surface or the bottom surface of the shelf body is provided with a groove, and the remaining surface is provided with a flat structure. The carrier bars pass through the connecting holes. The shelf body with a top surface and a bottom surface which is different from the top surface provides choices to users for placing wine bottles or other canned and bottled drinks vertically or horizontally. Further the arrangement of connecting holes through which the carrier bars pass enables the shelf bodies to be suspended on the carrier bars, and hence the shelf bodies are easy to be disassembled and convenient to be arranged in a reasonable way according to the real placement requirements for objects.
