Communication structure achieving the purpose of improving the communication quality

This invention discloses a communication structure for a mobile communication device. The system comprises a signal transmission module and a signal transceiver module, wherein the signal transmission module has a plurality of arrays of antenna units, and the signal transceiver module comprises a signal transceiver unit, a control unit and a power control unit, a spectrum signal source is generated by using the signal transceiver module, when the spectrum signal is transmitted to the mobile communication device, the mobile communication device receives and transmits a feedback signal, after the signal transmission module receives the feedback signal, the signal transceiver unit generates a feedback signal to the control unit, and after the control unit recognizes the feedback signal, it controls the corresponding array of antenna units to achieve the purpose of improving the communication quality.
