Abstract

A problem which must be solved if the coupled strip or any other evaporated strip line configuration is to be practical is the problem of connections of strip lines to external wires or coaxial cables. Pressure contact to thin evaporated strip lines is both difficult and unreliable because the evaporated strip line is too fragile to avoid fracturing and they are also subject to corrosion.

Feed Through Connectors to Striplines Evaporated on Insulated Ground Planes

A problem which must be solved if the coupled strip or any other evaporated strip line configuration is to be practical is the problem of connections of strip lines to external wires or coaxial cables. Pressure contact to thin evaporated strip lines is both difficult and unreliable because the evaporated strip line is too fragile to avoid fracturing and they are also subject to corrosion.

Thus, there is needed a connector which can be used to make electrical connection from a stripline to an external wire or coaxial cable.

The drawing shows the completed connector in cross-section. The ground plane can be solid conductor or a conductor-plated insulator. The countersunk hole into which the metal ground connector is fitted provides a mechanically solid bond to the substrate. If electrical connection between the ground connector and the ground plane is not reliable, additional metal can be coated over the connector by electroplating. An insulating layer and the strip lines are then formed over the ground plane.

A connecting nail is then driven through the hole in the ground plane so that the head of the nail comes down tight against the strip line. The body of the nail is coated with a cylinder of insulation to provide a tight mechanical fit to the ground connector and insulation from the ground. If electrical contact is not reliable, electroplating can again be used to perfect the connectio...
