Generally, the fully conductive cover 100 (e.g., a fully metal cover) has an effect of enhancing the aesthetic appearance of the mobile terminal 10000, but the fully conductive cover 100 (e.g., a metal cover) has a signal shielding function and cannot meet the design requirement of the antenna of the mobile terminal 10000. Therefore, the first gap strip 1 is disposed on the conductive cover 100 of the mobile terminal 10000, and the first gap strip 1 is filled with an insulating spacer layer (for example, a non-conductive plastic material), where the insulating spacer layer is a non-signal shielding material, which can reduce a shielding effect on an antenna signal of the mobile terminal 10000, so that the conductive cover 100 meets a design requirement of an antenna of the mobile terminal 10000.
In addition, the first slit band 1 and the second slit band 2 divide the conductive cover 100 into a first cover part 3, a spacing part 5 and a second cover part 4, the spacing part 5 is located between the first cover part 3 and the second cover part 4, the first cover part 3 can be used as a radiating body of the 10000 antenna of the mobile terminal, the signal of the 10000 antenna can be prevented from being shielded, and the first cover part 3 is arranged close to the first slit band 1, so that the shielding effect on the 10000 antenna signal of the mobile terminal can be further reduced.

In some embodiments of the present invention, as shown in fig. 1-4, the end of the first arcuate segment 12 connected to the second linear segment 13 extends away from the second slit band 2. Therefore, the second straight line segment 13 can be closer to the edge of the conductive cover body 100, and the appearance of the conductive cover body 100 is more attractive.

The second arcuate segment 131 divides the second linear segment 13 into two linear segments, both of which are perpendicular to the second sidewall 7, and the first arcuate segment 12 is located between the two linear segments. Thereby the length of the first slot strip 1 can be further increased, enhancing the radiation performance of the antenna structure. Note that the axis of symmetry of the conductive cover 100 is also the axis of symmetry of the first and second sidewalls 6 and 7.
In some embodiments of the invention, at least one end of the second slit tape 2 is in communication with the first slit tape 1.
