Embodiment 1
[0026] The multilayer ceramic antenna structure of Embodiment 1 is as figure 1 As shown: it includes ceramic medium 5 and multilayer radiation conductor strip 4 in ceramic medium 5, and also includes peripheral sealing metal 3 and edge isolation hole 6, and said edge isolation hole 6 connects the multilayer radiation conductor strip 4 The vertical overlapping portion protrudes from the surface of the ceramic medium and is used to isolate the adjacent peripheral termination metal 3 , which is used for the interlayer interconnection of the multilayer radiation conductor ribbon 4 .
[0027] The multilayer ceramic antenna here also includes an edge chamfer 7 arranged on the feeding surface of the ceramic medium 5, and the vertical overlapping part of the radiation conductor strip 4 and the external microstrip feeder 2 protrudes from the surface of the ceramic medium 5 for the radiation conductor Strip 4 is electrically connected to the external microstrip feeder 2 .

Embodiment 2
[0030] The multilayer ceramic antenna structure of embodiment two is as figure 2 Shown: similar to Example 1, including ceramic medium 5 and two layers of radiating conductor strips 4 located in ceramic medium 5, and also including peripheral sealing metal 3 and edge isolation hole 6, and ceramic medium 5 is stacked with two layers from top to bottom. A layer of radiating conductors 4, two layers of radiating conductors overlapped up and down together to form a serpentine curved antenna. According to the same idea, by simultaneously punching holes and cutting corners at the appropriate position on the peripheral edge of the vertically aligned LTCC components, the ceramic medium at the vertical overlap of the upper and lower conductors is protruded, so that it is convenient to connect the two conductors and the feeder through sealing .
[0031] The technological process adopted by the specific implementation example of the present invention is as image 3 As shown, it specif...
