Abstract
The present disclosure provides an antenna system for optimizing isolation and a mobile terminal. The system defines clearance slots in an electromagnetic conductor and between antenna feed points for optimizing isolation between antenna units, and comprises clearance areas disposed on both sides of the electromagnetic conductor having the clearance slots of the circuit board for arranging the antenna feed points. Through the present disclosure, it is possible to increase isolation between the diversity antenna and other antenna in a limited space, avoid the coupling effect between the antennas, and alleviate the problem present in traditional multiple-input multiple-output antennas limited by the size of the terminal device.
Claims14
An antenna system for optimizing isolation, wherein the system includes a circuit board, the circuit board being provided with:
- a clearance slot defined in an electromagnetic conductor of the circuit board and between antenna feed points for optimizing isolation between the antenna feed points;
- and
- at least two clearance areas disposed on both sides of the electromagnetic conductor having the clearance slot of the circuit board for arranging the antenna feed points;
- wherein neither the clearance areas nor the clearance slot contains an electromagnetic conductor;
- wherein the clearance slot is a rectangle lacking one side, wherein two opposite sides of the rectangle have a same width, and the same width is less than a width of one side between the two opposite sides of the rectangle;
- wherein the number of the clearance slot is at least two, and each of the at least two clearance slots is the rectangle lacking one side, any adjacent two rectangles are inverted-mirrored in a direction perpendicular to a direction in which lacked sides of the adjacent two rectangles are located, and a spacing is located between the adjacent two rectangles, such that the at least two clearance slots are in an inverted mirror slotted matrix.
A mobile terminal, wherein the mobile terminal comprises a circuit board, the circuit board being provided with:
- a clearance slot defined in an electromagnetic conductor of the circuit board and between antenna feed points for optimizing isolation between the antenna feed points;
- and
- at least two clearance areas disposed on both sides of the electromagnetic conductor having the clearance slot of the circuit board for arranging the antenna feed points;
- wherein neither the clearance areas nor the clearance slot contains an electromagnetic conductor;
- wherein the clearance slot is a rectangle lacking one side, wherein two opposite sides of the rectangle have a same width, and the same width is less than a width of one side between the two opposite sides of the rectangle;
- wherein the number of the clearance slot is at least two, and each of the at least two clearance slots is the rectangle lacking one side, any adjacent two rectangles are inverted-mirrored in a direction perpendicular to a direction in which lacked sides of the adjacent two rectangles are located, and a spacing is located between the adjacent two rectangles, such that the at least two clearance slots are in an inverted mirror slotted matrix.
