Miniaturized millimeter wave LTCC (Low Temperature Co-Fired Ceramic) band-pass filter based on embedded dielectric resonator

The utility model relates to the technical field of filters, in particular to a miniaturized millimeter wave LTCC (Low Temperature Co-Fired Ceramic) band-pass filter based on an embedded dielectric resonator, which comprises a metal layer consisting of a first metal plane, a second metal plane, a third metal plane, a fourth metal plane and a fifth metal plane; the dielectric layer is arranged between the metal layers, and the dielectric layer is composed of a first square dielectric plate, a second square dielectric plate, a third square dielectric plate and a fourth square dielectric plate. By arranging the metal layer and the dielectric layer, the device has the advantages of wide band, low profile, high selectivity, easiness in processing, miniaturization and the like; by arranging the dielectric resonator, the performance of the filter is improved, the physical size is remarkably reduced, and the filter has high engineering application value in 5G communication. 本实用新型涉及滤波器技术领域，具体为一种基于嵌入介质谐振器小型化毫米波LTCC带通滤波
