Patent ID: 7855685

Claim:
A microwave communication package, comprising: an electrically conducting base plate having a first side and a second side opposite the first side; a base plate cavity being defined in the first side of the base plate; an antenna apparatus mounted on the second side of the base plate; a dielectric substrate mounted to overlie and cover the base plate cavity defined in the first side of the base plate, said dielectric substrate having a first side being adjacent with the base plate cavity; a sealing apparatus for sealing the first side of the dielectric substrate with the first side of the base plate remote from the base plate cavity, and the sealing apparatus completely surrounding the dielectric substrate such that the base plate cavity is substantially hermetically sealed; electronic circuitry including one or more electronic components mounted on the first side of the dielectric substrate overlying the base plate cavity, the electronic circuitry further including one or more microstrip lines for microwave signal transmission disposed in the dielectric substrate and at least one ground plane member further disposed in the dielectric substrate; and one or more waveguides each comprising an opening extending through the base plate, and each waveguide being electrically coupled with the electronic circuitry and the antenna apparatus on the second side of the base plate.
