Abstract
Abstract A package for a microwave circuit chip and associated microstrip antenna is formed of a multi-layer ceramic laminate within which is supported a microwave chip carrier and on an outer surface of which a microstrip antenna disposed. A first ceramic layer is supported on metallic base member and contains signal lines for interfacing the chip with the external world. Disposed atop the first ceramic layer is a second ceramic layer which forms a protective seal ring around the perimeter of the chip. A third ceramic cover layer is mounted atop the seal ring layer and contains one or more antenna elements on its outer surface. Signal line connections between the chip and the antenna elements are effected through tuned networks that extend from signal leads on the chip to conductors on the first ceramic layer. Signal connections from the first ceramic layer to the antenna on the cover may be formed by conductive vias through the ceramic seal ring layer or conductors along sidewalls of the seal ring layer and cover. Preferably, the first layer and the seal ring layer contain a ground plane vias distributed around the perimeter of the chip, to provide electrical continuity between the metal base member and a ground plane on the interior surface of the cover.
