  • Antenna-integrated microwave-millimeter wave module
    Publication number: 20020070901
    Abstract: A microwave circuit or a millimeter wave circuit is formed on a semiconductor chip. A multilayer substrate is formed of a first dielectric layer, a second dielectric layer and a third dielectric layer. A high-frequency circuit line with the semiconductor chip mounted thereon is formed on the third dielectric layer. A slot hole is formed on one side of the second dielectric layer and an antenna feeding line is formed on the other side. The first dielectric layer has a plurality of slot holes formed therein that radiate electromagnetic waves. An organic substrate is laminated to the multilayer substrate by an adhesion layer.
    Type: Application
