  • Three-pole three-throw switch and communication device
    Patent number: 8299843
    Abstract: A three-pole three-throw switch and a communication device employing the three-pole three-throw switch includes six diodes and six inductors. The six diodes are connected in series with a same direction. Common nodes of each two diodes form three poles and three throws. The three poles and the three throws are linked together in circular form. The three poles and the three throws receive control signals via the six inductor, respectively.

  • Multiple-input multiple-output device
    Patent number: 8242967
    Abstract: A multiple-input multiple-output (MIMO) device includes a substrate, a shielding cover and a MIMO antenna. The shielding cover is positioned on the substrate, and includes a plurality of sidewalls. The MIMO antenna includes a first solid antenna, a second solid antenna, and a plane antenna. The first solid antenna and the second solid antenna are electrically connected to two ends of one sidewall of the shielding cover, respectively. The first plane antenna is configured on the substrate, and disposed between the first solid antenna and the second solid antenna.
