Title:
COMMUNICATION DEVICE SUPPORTING MULTIPLE-INPUT MULTIPLE-OUTPUT TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2018/148973
Kind Code:
A1
Abstract:
An embodiment of the present invention provides a communication device supporting a multiple-input multiple-output technology. The communication device comprises a primary antenna and a MIMO antenna. A first gap is arranged between one end of the primary antenna and one end of the MIMO antenna. The primary antenna is connected to a first feed on a first point, and is at least used for transmitting a signal in a first working frequency band. An isolation circuit is disposed between the primary antenna and the MIMO antenna, and is used for reducing the coupling between the primary antenna and the MIMO antenna. The MIMO antenna and a second optional feeding circuit are connected on a second point. The second optional feeding circuit can be selectively switched between a feed state and a non-feed state, and comprises a second feed. The MIMO antenna is used for transmitting a signal in the first working frequency band. When the second optional feeding circuit is in the feed state, the MIMO antenna and the primary antenna are simultaneously used for transmitting a signal in the first working frequency band; and when the second optional feeding circuit is the non-feed state, the MIMO antenna is used as a parasitic structure for the primary antenna.
