TRANSMISSION LINE CONNECTION STRUCTURE

Embodiments of this application provide a transmission line connection structure, and relate to the antenna field. The transmission line connection structure includes a first transmission line, a second transmission line, and a coupling connection structure. The first transmission line corresponds to a first ground layer and a conductor strip. The second transmission line corresponds to the conductor strip and a second ground layer. The first ground layer and the second ground layer are discontinuous. The coupling connection structure includes a first coupling section (101), a second coupling section (102), and a third coupling section (103). A conductor part of the first coupling section (101) is coupled to the first ground layer, and a conductor part of the third coupling section (103) is coupled to the second ground layer. The second coupling section (102) is connected to the first coupling section (101) and the third coupling section (103). The coupling connection structure is configured to be coupled to the first ground layer and the second ground layer.
