  • Planar antenna for beam scanning
    Patent number: 6720931
    Abstract: A beam scanning plane antenna is formed by stacking, in order, a system connecting portion, a Rotman lens portion, and a beam scanning antenna portion. The system connecting portion is formed by stacking, in order, a fourth grounding conductor, a sixth dielectric, a connecting substrate and a fifth dielectric. The Rotman lens portion is formed by stacking, in order, a third grounding conductor, a fourth dielectric, a Rotman lens substrate and a third dielectric. The beam scanning antenna portion is formed by stacking, in order, a second grounding conductor, a second dielectric, a power feeding substrate, a first dielectric and a first grounding conductor. A plurality of antenna groups that each include an irradiating element, a power feeding line and a first connecting portion, are formed on the power feeding substrate. The Rotman lens substrate includes a Rotman lens pattern, a second connecting portion and a third connecting portion.

  • Multi-layer line interfacial connector using shielded patch elements
    Patent number: 6545572
    Abstract: This triplate line interfacial connector electrically connects a first triplate line comprised of a first grounding conductor, first dielectric, first power feeding substrate, second dielectric and second grounding conductor, and a second triplate line comprised of a second grounding conductor, third dielectric, second power feeding substrate, fourth dielectric, and third grounding conductor. A patch pattern is formed at a connecting terminal portion of each power feeding line. Two shield spacers each having a through portion around the patch pattern are provided. A first slot is formed at a connecting position between the two triplate lines in the second grounding conductor.
