ABSTRACT:
A signal transmission structure is at the edge of a circuit board, and the circuit board is connected with a coaxial cable connector through the signal transmission structure. The coaxial cable connector has a signal pin and a plurality of supporting pins for clipping the circuit board. The signal transmission structure includes a reference plane and a conductive layer. The reference plane with a non-conductive area is inside the circuit board. The conductive layer is disposed on the surface of the circuit board and above one side of the reference plane. The conductive layer includes a signal pad and a signal line. The signal line is connected with the signal pad, and the signal pad is further connected with the signal pin of the coaxial connector. The projections of the signal pad and the portion of the signal line on the reference plane are in the non-conductive area.
