The metal device 1 here can be regarded as a component of the terminal product, such as a metal frame, a metal shell or other metal frame, or a metal complete device of the terminal product. Based on this, the dual-band WIFI antenna group 3 is electrically connected to the working feed point of the mainboard formation 2 on the one hand, and is spatially arranged around the first working surface 11, the second working surface 12 and the working side surface 13 through the first PDS antenna branch 31 and the second PDS antenna branch 32, thereby ensuring the spatial three-dimensional structure and multi-angle spatial radiation of the dual-band WIFI antenna, that is, the metal device 1 and the mainboard formation 2 are coupled with the dual-band WIFI antenna group 3 to reduce the antenna usage area, improve the antenna directivity and performance, and meet the design requirements of miniaturization of the terminal product, thereby reducing the antenna usage ratio in a limited terminal assembly space.

The first direction, the second direction and the third direction are perpendicular to each other. Of course, the direction design of this embodiment is not limited to this. XYZ can also be any other directions perpendicular to each other in space in actual work needs, which will not be repeated here.

[0036] That is, the third PDS antenna branch 33 is connected to the working side surface 13 by the PDS antenna substrate 30 and then extended along the first direction on the working side surface 13 to expand the spatial three-dimensional structure arrangement of the dual-band WIFI antenna group 3, wherein the end of the third PDS antenna branch 33 is provided with a third connecting portion 331, and the third connecting portion 331 is arranged at the connection between the second working surface 12 and the working side surface 13, thereby improving the space utilization of the antenna arrangement in the limited terminal assembly space.

The bending portion 351 extending along the first direction can form a 90° right angle with the fifth PDS antenna branch 35 extending along the second direction, thereby making full use of the effective area of ​​the second working surface 12 and improving the space utilization of the antenna arrangement in the limited terminal assembly space.

[0039] Among them, one end of the metal device 1 of this embodiment constitutes a working recessed platform structure 4 relative to the whole of the metal device 1, and the folded main board stratum 2 is located on the working recessed platform structure 4. Specifically, the first connecting part 311 and the second connecting part 321 are stacked on the working recessed platform structure 4 with the main board stratum 2, so that there is sufficient air space for the connection between the dual-band WIFI antenna group 3 and the main board stratum 2.
