A host with multiple antennas so as to be capable of Wi-Fi and X-box functioning includes a chassis, and first to fourth antennas. The first antenna and the second antenna are each on an edge area of a first side wall of the chassis, the third antenna is located on a second side wall of the chassis, and the fourth antenna is located on a third side wall of the chassis. The first side wall is located between the second side wall and the third side wall, and the second side wall is located opposite to the third side wall. A separation distance between every two antennas of the first to fourth antennas is greater than a predetermined distance and enables isolation requirements for all antenna types to be met.
