Abstract: A mobile terminal device is disclosed. The mobile terminal device includes a metal rear cover; a metal frame forming an accommodation space with the metal rear cover; a printed circuit board assembly; and an antenna module inside the accommodation space and electrically connected with the printed circuit board assembly. The antenna module includes a grounding terminal and a feeding point disposed on the printed circuit board assembly. The metal rear cover includes a first metal part, a second metal part, a third metal part and the two coupled gap. The first metal part and the third metal part are connected to both ends of the second metal part.

Abstract: A mobile terminal device is provided in the present disclosure. The mobile terminal device includes a metal back cover with a groove, a printed circuit board with a groove opening corresponding to the groove, and an antenna module. The antenna module includes a radiator body and a groove adaptor member, at least part of the metal back cover serves as the radiator body of the antenna module. The groove adaptor member includes a groove adapting part and a supporting part for supporting the groove adapting part, the groove adapting part includes a main body, a first extending piece and a second extending piece. The main body is received in the groove opening and aligned with the groove; the first extending piece and the second extending piece respectively extend from two opposite edges of the main body and are connected to the printed circuit board.

Abstract: A self-configurable resonance antenna includes a main antenna for transmitting and receiving radio waves of a plurality of mutually different frequency bands, a coupling element having at least two radiating patches with different effective electrical lengths for configuring the impedance of the self-configurable resonance antenna, and a matching circuit disposed between the main antenna and the coupling element. The matching circuit has a filter, a RF detector, a switching logic and a RF switch, the RF switch switching between at least the two radiating patches with different effective electrical lengths for adjusting the main antenna operating in different frequency bands.
