In the wireless telephone device to which 0 is attached, the RF connection connector for measuring the RF performance needs to be provided in the housing 20 separately from the antenna 10, and therefore the retractable antenna 10 and the RF connection are used as the input / output system for the wireless circuit. It will have two systems with a connector. This has the advantage that when the wireless telephone device is attached to the in-vehicle set (hands-free set), it is possible to switch from the antenna on the device side to the external antenna with one touch, but on low-end mobile phone models, switching to the external antenna is possible. Is a function that is not always necessary. On the contrary, by providing two input / output lines, a connector and a changeover switch are required, which is a great cost disadvantage.
