  • Patent number: 8538497
    Abstract: A fixing structure including a metal housing and a fixing base is disclosed. The housing has a carrying plane and the fixing base having a first contact end and, opposite, a second contact end is disposed on the housing. The perpendicular distance from the first contact end to the carrying plane is greater than that from the second contact end to the carrying plane. A wireless transmission device is disposed on the fixing base and in contact with the first contact end and the second contact end, so that a perpendicular distance from an antenna end of the wireless transmission device to the carrying plane is greater than a perpendicular distance from a fixed end of the wireless transmission device to the carrying plane. Therefore, a relatively great distance is kept between the antenna end and the housing for preventing the antenna end from being interfered by the metal housing.
