  • Multi-frequency antenna module for a portable electronic apparatus
    Publication number: 20040222928
    Abstract: A multi-frequency antenna module for a portable electronic apparatus includes a dielectric substrate mounted in a housing of the apparatus. A micro-strip conductor is disposed on a first surface of the substrate. A radiating element is disposed on an opposite second surface of the substrate and is coupled electrically to the micro-strip conductor. A grounding metal plate is mounted on the second surface of the substrate and is coupled electrically to the radiating element. A transmission line has a first conducting portion coupled electrically to the micro-strip conductor, and a second conducting portion coupled electrically to the grounding metal plate.

  • Multi-frequency antenna for a portable electronic apparatus
    Patent number: 6809689
    Abstract: A multi-frequency antenna for a portable electronic apparatus includes a dielectric substrate mounted in a housing of the apparatus. A radiating element is disposed on a first surface of the substrate. A micro-strip conductor is disposed on an opposite second surface of the substrate and is coupled electrically to the radiating element. A grounding metal layer is disposed on the second surface of the substrate, is electrically isolated from the conductor, and is coupled electrically to the radiating element. A transmission line has a first conducting portion coupled electrically to the micro-strip conductor, and a second conducting portion coupled electrically to the grounding metal layer.
