Abstract
A thin film flexible multi-conductor transmission line having a ground plane deposited on one surface of a flexible thin film insulating member and an array of conductors and pairs of conductors deposited on another surface of the insulating member opposite the ground plane. An electrical shield is positioned above the conductor array to reduce radiation emissions from the conductors into the surrounding environment and to minimize noise sensitivity of the conductors from external emission sources. Insulating material is positioned about sides of and in between the conductors and the shield wherein a ratio of the insulating material height to a height of the conductors is selected at predetermined values and which supports the shield independent of the conductors and insulates each conductor and the conductor array from the shield. Corresponding driver and receiver circuits integrated within the transmission line are each coupled with conductors for transmitting and receiving digital signals on the conductors. A pair of connectors integrated within the transmission line and connected with the driver and receiver circuits couple the transmission line to signal sources and destinations. Interconnected receiver and driver circuits may be integrated within the transmission line at predefined locations along the transmission line conductors and connected thereto for receiving propagated signals appearing on ones of the conductor pairs and to propagate the received signals on others of the conductor pairs.
