A wireless charging mobile communication device includes a wireless communication module, an electricity storage module, a converting module, an antenna module and a switching module. The antenna module receives and transmits wireless signal or electromagnetically induces a current. The switching module is electrically coupled to the antenna module, the wireless communication module, and the converting module. The switching module is for connecting the antenna module with the wireless communication module or connecting the antenna module with the converting module. The converting module is electrically coupled to the electricity storage module and converts the electromagnetically induced current for facilitating a charging of the electricity storage module. The converting module, the antenna module, and the switching module are integrated as an antenna device.
