  • Patent number: 7834809
    Abstract: The present invention discloses a multi-antenna integration module, which comprises a first antenna, a second antenna and a common unit. The first antenna further comprises a first feeder cable, a first feeder member, a coupling unit, which has a first and second coupling members, and an extension conductor. The second antenna further comprises a second feeder cable, a radiation conductor and a coupling conductor. The common unit further comprises a common conductor which has a first and second conductor, a common short-circuit member and a common ground member. In the present invention, the design of the common unit integrates the radiation conductors, short-circuit members and ground members of different antenna systems into a single structure, whereby the isolation effect is promoted, and the signal interference among different antennae is decreased, and the space occupied by the antenna layout is reduced.
