  • Publication number: 20120194391
    Abstract: A multi-input multi-output (MIMO) antenna system includes multiple antennas, a ground part and an isolating part. The isolating part is disposed between each two adjacent antennas. The isolating part is electrically connected to the ground part. A distance exists between an end of the antenna and an end of the isolating part. A circuit board applying the MIMO antenna system is also disclosed. Since the isolating part is disposed between each two adjacent antennas, signal interference between the antennas can be prevented, and the MIMO antenna system and the circuit board applying the same have better isolation.

  • Patent number: 6870513
    Abstract: An antenna module includes a circuit board, a differential-type amplifier, and a dipole antenna. The dipole antenna can be formed with two electrodes disposed on the circuit board. With the structure of the antenna module, a transmitting antenna can be designed by coupling the two electrodes of the dipole antenna to output terminals of the differential-type amplifier so as to transmit signals. In design of a receiving antenna, the two electrodes of the dipole antenna can be coupled to input terminals of the differential-type amplifier so as to receive signals. Further, if the main function chip has built-in differential power amplifier or differential low noise amplifier, a circuit module for wireless signal transmitting and receiving can be formed by directly coupling the dipole antenna to the differential power amplifier or the differential low noise amplifier.
