A wireless communication apparatus with built-in terminal hub for transmitting a wireless signal includes a PCB, built-in antenna module and input terminal hub. The built-in antenna module disposed on the PCB transmits the wireless signal and the input terminal hub coupled with the PCB connects the computer. It avoids bringing the surrounding electromagnetic interference (EMI) and disorder. Besides, the built-in antenna module makes the whole size smaller and easy to carry. The wireless communication apparatus further provides an extended output terminal hub for connecting other peripheral device.
