PROBLEM TO BE SOLVED: To provide a wireless mobile equipment in which a signal loss from a transmitting circuit to an antenna terminal is reduced and the connection of the transmitting circuit, a receiving circuit, two antenna terminals and two external connector terminals can be switched in simple configuration. SOLUTION: In the wireless mobile equipment provided with an antenna and the external connector terminals, the equipment is provided with a switch circuit 12 having a plurality of switch elements for switching the connection of an antenna 14 for transmitting/receiving, an antenna 15 for receiving, external connector terminals 16 and 17, a transmitting circuit 1 and a receiving circuit 2 and a control means 13 for controlling the operation of the respective switch elements in the switch circuit and the switch circuit is electrically switched by a signal from the control means. Since only the switch circuit is interposed between the antenna and external connector terminals and the transmitting and receiving circuits, the signal loss is reduced. By connecting various kinds of external devices to the external connector terminals and changing how to control the switch circuit, various uses are enabled. COPYRIGHT: (C)2003,JPO
