Abstract:
1. A transmission line system arranged on a PCB which comprises a first layer, a second layer, and a third layer in sequence, the transmission line system comprising: a first transmission line, one part of the first transmission line being arranged on the first layer of the PCB, other part of the first transmission line being arranged on the third layer of the PCB; the part of the first transmission line arranged on the first layer of the PCB comprising a plurality of first structure units, each of the plurality of first structure units comprising a first connection line, a second connection line, and a first bent line, each of the first connection lines and each of the second connection lines being straight lines, the first bent line first end being connected to the first connection line first end, and the first bent line second end being connected to the second connection line first end; the other part of the first transmission line, arranged on the third layer of the PCB, comprising a plurality of second structure units; each of the plurality of second structure units comprising a third connection line, a fourth connection line, and a second bent line; each of the third connection line and the fourth connection line being straight lines, the second bent line first end being connected to the third connection line first end, and the second bent line second end being connected to the fourth connection line first end; the first connection line second end of each of the plurality of first structure units being connected to the third connection line second end of the adjacent second structure unit through a respective via, and the second connection line second end of each of the plurality of first structure units being connected to the fourth connection line second end of the adjacent second structure unit through another respective via; and a second transmission line being a straight line arranged on the second layer of the PCB; wherein each of the first bent lines and each of the second bent lines are “L-shaped”, and the first transmission line and the second transmission line are configured to transmit signal which comprises at least one item selected from the group consisting of the common-mode signal and the differential-mode signal.
