Claim Text:
1. A printed circuit board (PCB) comprising: a first ground layer elongating in one direction; a first dielectric layer deposited on a top of the first ground layer and elongating in the same direction as the first ground layer; a signal transmission line deposited on a top of the first dielectric layer and elongating in the same direction as the first dielectric layer; a ground pad elongating from one end of the first ground layer and in contact with an external ground; a signal line pad extended from one end of the signal transmission line and in contact with an external signal line; and a ground pad area formed on a bottom of the one end of the first dielectric layer while the signal line pad is formed on a bottom of the ground pad area, wherein the ground pad is formed on a bottom of one end of the first ground layer, and wherein the ground pad area is electrically segregated from the first ground layer by etching a peripheral portion of the first ground layer, on which the signal line pad is deposited.
