一種開槽型信號傳輸電路板結構，其可整合至一高速數位傳輸系統，用以對該高頻電路系統提供一低損耗之信號傳輸功能。此開槽型信號傳輸電路板結構的特點在於形成一開槽結構部(即空洞之溝槽)於導電性之接地面上，且此開槽結構部係位於信號線路的下方。此作法可使得高速數位信號於通過信號線路時，其所產生之電場於此空洞之開槽結構部之處產生漏電流降低，藉此降低漏電流造成傳輸信號的能量損耗。
A ground-plane slotted type signal transmission circuit board is proposed, which is designed for use with a high-speed digital signal processing system for providing a low-loss signal transmission function. The proposed circuit board structure is characterized by the formation of a slotted structure (i.e., elongated cutaway portion) in the ground plane at the beneath of each signal line. Since the slotted structure is a void portion, the electric field of a gigahertz signal being transmitting through the overlaying signal line would be unable to induce electric currents in the void portion of the ground plane. This feature allows the prevention of a leakage current that would otherwise flow from the signal line to the ground plane, and therefore can help prevent unnecessary power loss of the transmitted signal.
