Therefore, it has become the mainstream development trend of terminal products in recent years and is favored by various terminal manufacturers. . However, the design of the full screen brings great challenges to the antenna. FIG. 1 shows a prior art solution for the antenna structure of a full-screen wireless electronic communication device. A break 103 is provided on the metal frame 102 around the periphery of the display screen 101, and then an antenna radiating arm 104 is formed on the metal frame 102. Due to the effective radiation of the antenna, the clear area 105 is required, but the screen ratio in related technologies is getting higher and higher, exceeding 90%. The transparent conductive material (Indium Tin Oxides, ITO) traces of the screen are getting closer and closer to the antenna. Greatly reduces the radiation efficiency of the antenna, thereby affecting the quality of wireless communication and reducing the user experience. And the future 5G not only has Sub-6GHz frequency band, but also millimeter wave frequency band, and for higher data transmission rate, it also needs to support 4*4 Multiple-Input Multiple-Output (MIMO), wireless electronic communication The number of antennas required by the device will increase. Compared with the traditional 4G wireless electronic communication equipment, the number of antennas will be significantly increased in predictability, and even reach more than ten antennas. Therefore, it is necessary to break the seam on the appearance metal frame The number of corresponding increases, and the breaking seam will affect the reliability of the overall structure and the aesthetic appearance.

In summary, as the screen ratio becomes higher and higher, opening a break in the frame will make the antenna's clearance area less and less, close to zero clearance, will greatly reduce the antenna's radiation efficiency. And with the increase in the number of 5G antennas in the future, it may be necessary to open a greater number of broken seams, so it will affect the structural strength and reliability of the whole machine, and it will also affect the aesthetic appearance. In addition, the broken seam of the related art is directly exposed on the appearance, and the user may touch the position of the broken seam in the hand-held state, causing a shift in the antenna resonance frequency and absorption of electromagnetic wave signals, which greatly reduces the antenna radiation efficiency, thereby affecting wireless communication the quality of. In addition, when the user is talking on the phone, the previous design of slitting the metal frame on the exterior will cause a high radiation effect on the human body.

The metal frame 1 includes a first side and a second side opposite to each other, wherein the second side is on the same side as the display screen, and the first side is on the same side as the battery. The second slit 112 of the opening slit 11 extends from the first side of the metal frame 1, and the corresponding extension distance is less than the distance between the first side and the second side, the first side here The distance from the second side is the width of the metal frame 1.

The main floor is connected to the inner side wall of the metal frame 1; in the width direction of the metal frame 1, the main floor divides the metal frame 1 into a first metal frame 31 and a second metal frame 32, the first side The side is located in the first metal frame 31, the second side is located in the second metal frame 32, the first slit 111 is located in the first metal frame 31, and the length of the second slit 112 is less than or equal to that of the first metal frame 31 width.

The main floor provided inside the metal frame 1 can be integrally connected with the four inner walls of the metal frame 1. This method can ensure a firm connection between the two, and the thickness of the main floor is less than the width of the metal frame 1. By providing the main floor integrally connected to the inner wall of the metal frame 1, the metal frame 1 can be divided into the first metal frame 31 and the second metal frame 32 in the width direction of the metal frame 1. The sizes of the first metal frame 31 and the second metal frame 32 are not further limited here.

The first side of the metal frame 1 is located on the first metal frame 31, and the second side of the corresponding metal frame 1 is located on the second metal frame 32. Since the second side is the metal frame 1 and the display screen The sides on the same side, so the display screen can be set in the second metal frame 32, and the corresponding battery is set in the first metal frame 31.

The first end surface of the main floor may cooperate with the first metal frame 31 to form a first accommodating space, and the second end surface of the main floor may cooperate with the second metal frame 32 to form a second accommodating space. Due to the arrangement of the main floor, The sum of the depth of the first accommodating space (the width of the first metal frame 31) and the depth of the second accommodating space (the width of the second metal frame 32) is smaller than the width of the metal frame 1. The display screen is set in the second accommodating space, and the corresponding battery is set in the first accommodating space.

At this time, the first accommodating space may correspond to two areas for accommodating the motherboard and the battery, respectively. Since the extension distance corresponding to the second slit 112 extending from the first side of the metal frame 1 is less than or equal to the width of the first metal frame 31, one end surface of the metal isolation plate and the display screen can be kept intact and It can serve as a ground for the antenna structure, which isolates the display screen from the opening slit 11, reducing the influence of the display screen, especially the extreme full screen, on the antenna.

And because the end face of the metal isolation plate and the display screen is kept intact, the radiation of the antenna toward the display screen side will be blocked by a higher proportion than the traditional design with a slit on the appearance surface, so the radiation direction is basically non-oriented The user's head can effectively reduce the head SAR, which can effectively improve the compliance of human safety regulations.
