摘要:
The present invention relates to the field of integrating electronic systems that operate at mm-wave and THz frequencies. A monolithic multichip package, a carrier structure for such a package as well as manufacturing methods for manufacturing such a package and such a carrier structure are proposed to obtain a package that fully shields different functions of the mm-wave/THz system. The package is poured into place by polymerizing photo sensitive monomers. It gradually grows around and above the MMICs (Monolithically Microwave Integrated Circuit) making connection to the MMICs but recessing the high frequency areas of the chip. The proposed approach leads to functional blocks that are electromagnetically completely shielded. These units can be combined and cascaded according to system needs.

A feeding structure including a carrier substrate, a top conductor plane of a cavity formed in the carrier substrate, a feedline substrate covering the top conductor plane, a signal conductor of a feedline, the signal conductor being formed in or on the feedline substrate opposite the top conductor plane, a via probe connected to the signal conductor and leading through the feedline substrate and the top conductor plane into the cavity, a ring-shaped aperture formed in the top conductor plane around the via probe, and at least one slot-shaped aperture formed in the top conductor plane starting at the ring-shaped aperture and leading away from the via probe.
摘要:
The present invention relates to a feeding structure for coupling a feedline to a cavity. To increase the coupling, which can contribute to achieving a broad bandwidth, a feeding structure is proposed comprising a carrier substrate, a top conductor plane of a cavity formed in said carrier substrate, a feedline substrate covering said top conductor plane, a signal conductor of a feedline, said signal conductor being formed in or on said feedline substrate opposite said top conductor plane, a via probe connected to said signal conductor and leading through said feedline substrate and said top conductor plane into said cavity, a ring-shaped aperture formed in said top conductor plane around said via probe, and at least one slot-shaped aperture formed in said top conductor plane starting at said ring-shaped aperture and leading away from said via probe.
