Embodiment Construction
[0062] The convex cavity multimode resonant structure mentioned in the following embodiments includes:
[0063] The cavity is similar to a cube, and the dielectric resonance block is convex, and the dielectric support frame;
[0064] The cavity is convex, and the dielectric resonance block is similar to a cube, and the dielectric support frame;
[0065] Both the cavity and the dielectric resonance block are convex, and the dielectric support frame;
[0066] The medium support frame is made to match the structure, and the number can be one or more. The shape can be a regular shape, such as a solid / hollow cylinder, a solid / hollow square column, etc., or an irregular shape; or it can be composed of multiple columns.
[0067] In order to ensure multi-mode and corresponding frequency, the structure cannot be infinitely convex or convex, and there are certain restrictions. An example is given below to illustrate, and others can be obtained similarly.
[0068]Eg: Single cavity 26...
