The third antenna 630 is disposed between the first antenna 610 and the second antenna 620 to affect the radiation patterns of the first and second antennas 610 and 620 to improve the isolation. In addition, since the third antenna 630 and the other two antennas 610 and 620 are different types of antennas, I are between the third antenna 630 and the first antenna 610, or between the third antenna 630 and the second antenna 620. There is generally no problem with signal interference. For example, the first and second antennas 610 and 620 are WLAN antennas, and the third antenna 630 is a 3G antenna. In most cases, the WLAN antenna and the 3G antenna do not simultaneously transmit and receive signals, and the signals transmitted and received by the two antennas are The frequencies are different, so there is less interference with each other.
