    摘要: A high frequency signal transmission line having reduced noise. Particularly, a signal transmission line of the current invention has reduced radiation noise and reflection noise, because a conventional ground guard fence line disposed between signal lines is separated into a plurality of ground line blocks that are spaced apart from each other to shield against noise.
