Antenna module, signal enhancement device and communication device

A signal enhancement device, suitable for a main body with a communication antenna, the signal enhancement device comprising:

• a back cover, the back cover including a backboard for covering a rear surface of the main body and a top board connected with a top end of the backboard for covering a top of the main body;
• and
• an antenna module set in a top of the back cover for coupling with the communication antenna, the antenna module including a base portion of board shape, a first bending portion connected with a top edge of the base portion, a second bending portion connected with a distal end of the first bending portion and a third bending portion connected with a distal end of the second bending portion;
• wherein the base portion is fixed in a portion of an inside surface of the backboard adjacent to the top board, the first bending portion is fixed in an inside surface of the top board, the second bending portion is fixed in a front end face of the top board, the third bending portion is fixed in an outside surface of the top board and a portion of an outside surface of the backboard adjacent to the top board.

A communication device, comprising:

• a main body having a communication antenna therein for executing communication functions;
• and
• a signal enhancement device mounted on the main body, the signal enhancement device including a back cover and an antenna module, the back cover including a backboard for covering a rear surface of the main body and a top board connected with a top end of the backboard for covering a top of the main body, the antenna module set in a top of the back cover, the antenna module facing to and spaced from the communication antenna for coupling with the communication antenna, the antenna module including a base portion of board shape, a first bending portion connected with a top edge of the base portion, a second bending portion connected with a distal end of the first bending portion and a third bending portion connected with a distal end of the second bending portion;
• wherein the base portion is fixed in a portion of an inside surface of the backboard adjacent to the top board, the first bending portion is fixed in an inside surface of the top board, the second bending portion is fixed in a front end face of the top board, the third bending portion is fixed in an outside surface of the top board and a portion of an outside surface of the backboard adjacent to the top board.
