Abstract
A planar filter connector is disclosed for the transmission of signals to be passed in and out of an EMI shielded enclosure. The EMI enclosure has walls the free ends of which are provided with an electrically conductive, resilient gasket. The filter connector is located on a conductive pad on a printed circuit board and is positioned under a portion of one of the walls, the gasket being depressed to accommodate the filter connector. The connector consists of a planar conductor surrounded by high dielectric material and further surrounded by two planar metallization layers. One metallization layer is in electrical contact with the gasket and the other metallization layer is in contact with the conductive pad. Shielding through the connector is maintained by the capacitance created between the conductor and each of the metallization layers.
