In order to keep the antenna structure with good radiation signals without additionally increasing the size of the electronic device, the antenna structure is mounted on the outer surface of the substrate to form an antenna assembly. The following description will be made in detail by taking an antenna assembly as an example.

Specifically, the printed antenna can be formed by adopting a PDS process, wherein the PDS process is a process for printing the mobile phone antenna, conductive silver paste is coated on the outer surface of the frame 181, and then the conductive three-dimensional circuit is formed by printing the silver paste in multiple layers. The PDS has the advantages that circuits can be directly printed, special laser modified materials are not needed, and the cost can be greatly reduced. In the antenna design, the antenna is difficult to process at the corner, and the circuit conduction can be realized on the structure of the through hole.

In the embodiment of the present application, the protection member 240 is made of a non-metal material, such as a plastic material, to ensure the radiation performance of the first antenna structure 210, and protect the first antenna structure 210 placed on the platform structure 230 from being damaged.

Compare in the internal surface with antenna structure 210 setting at frame 181, under the condition that does not increase electronic equipment overall dimension, antenna structure 210 has kept away from the distance of a frame 181 thickness at least, has pulled open antenna structure 210 and electronic equipment internal electronic component's distance, increases the antenna headroom district for the antenna can not receive electronic equipment internal component's influence, has improved the performance of antenna, has reduced electronic equipment's manufacturing cost.

Referring to fig. 4 and 5, in some embodiments, the corner 1813 is recessed toward a side adjacent to the inlay 812 to form a sinker structure 230 for placement of the first antenna structure 210. The sinker structure 230 has a first side wall 231, a second side wall 232, and a bottom wall 233 for connecting the first side wall 231 and the second side wall 232. The bottom wall 233 is connected to the first side 1811 through the first sidewall 231, the bottom wall 233 is connected to the second side 1812 through the first sidewall 232, and the bottom wall 233 has a height difference with the first side 1811 and the second side 1812. The height difference between the bottom wall 233 and the first side edge 1811 is equal to the height difference between the bottom wall 233 and the second side edge 1812.

In some embodiments, the first sidewall 231 and the first side 1811 form a rounded or arc structure, so that the electronic device 100 is smoother in appearance and less prone to damage when dropped.

In some embodiments, the first side wall 232 and the second side 1812 form a rounded or arc structure to make the electronic device 100 smoother in appearance and less prone to damage when dropped.

In some embodiments, the first antenna structure 210 is attached to the surface of the bottom wall 233. The protector 240 is disposed on the counter structure 230 on which the first antenna structure 210 is placed, and cooperates with the counter structure 230 to cover the first antenna structure 230 such that the first antenna structure 210 is located between the protector 240 and the counter structure 230.

In the embodiment of the present application, the number of the protecting members 240 may be set according to the number of the first antenna structures 210, for example, if the frame 181 is rectangular and has four corners, that is, if the frame 181 includes four corners 1813, the four protecting members 240 are set to respectively protect the first antenna structures 210 disposed at each corner 1813.

In some embodiments, referring to fig. 6, the protector 240 has adjacent first and second

outer surfaces

241, 242. The protector 240 is placed on the platform structure 230 such that the first outer surface 241 of the protector 240 is flush with the outer surface of the first side 1811 and the second outer surface 242 of the protector 240 is flush with the outer surface of the second side 1812. In practical applications, the first outer surface 241 of the protection member 240 is connected to the second outer surface 242 to form an arc surface.

In some embodiments, the substrate 18 has a first end and a second end, which are respectively located at two opposite ends of the substrate 18, such as the first end located at the top of the electronic device and the second end located at the bottom of the electronic device 100.

Therefore, the first antenna structure 210 is wrapped on the surface of the frame 181 by the protection member 240, so that the first antenna structure 210 is protected, the possibility of damage to the first antenna structure 210 is reduced, meanwhile, the protection member 240 is made of a non-metal material, the signal transmission of the first antenna structure 210 is not affected, and the signal transmission performance of the antenna structure is ensured.

In some embodiments, the first antenna structure 210 and the second antenna structure 220 may be both steel plate antennas or flexible circuit board antennas. When the first antenna structure 210 and the second antenna structure 220 are both patch antennas, a feed point structure may be provided in the patch antenna. Specifically, the feed point structure is formed by bending a steel sheet.

As shown in fig. 7 to 9, the first antenna structure 210 and the second antenna structure 220 are both steel plate antennas, and the steel plate antennas are attached to the outer surface of the first side 1811 and the outer surface of the corner 1813 of the bezel 181. The steel sheet antenna is provided with a connecting piece 221, and the connecting piece 221 is fixedly connected with the frame 181 so as to fix the steel sheet antenna on the outer surface of the frame 181.

In some embodiments, the connecting member 221 is formed from the upper and lower end edges of the frame 181 and is fixedly connected to the first side 1811 of the frame 181, the connecting member 221 may be a screw rod, the screw rod is in threaded connection with the frame 181, the connecting member 221 may also be a buckle, and the buckle is buckled into the frame 181 to realize a fixed connection such as a fixed connection.

Owing to adopt the connected mode of screw rod, buckle, need stretch into the connecting piece the darker position of frame 181, because the connecting piece adopts metal material in order to guarantee to connect length usually, when the connecting piece stretches into the inside overlength of frame 181, still can reduce the area in antenna headroom district, is unfavorable for the use of steel sheet antenna.

Next, the second antenna structure 220 will be described in detail by taking the second antenna structure 220 as a patch antenna 220 as an example. Specifically, the connecting element 221 extends from the steel sheet antenna 220 to one side of the frame 181, and the connecting element 221 is connected to the frame 181, it can be understood that the connecting element 221 and the frame 181 are formed by injection molding, the frame 181 covers the frame 181, and the connecting element 221 is fixed inside the frame 181.

In some embodiments, when one side of the first antenna structure 220 includes three or more connecting elements 221, the connecting elements 221 located on the same side are uniformly arranged. The connection between the connection member 221 and the frame 181 may be more uniform due to the uniform arrangement of the connection member 221.

second sides

222 and 223, the spacing between the connector 221 and the connector 221 of the first side 222 being the same as the spacing between the connector 221 and the connector 221 of the second side 223. The distance between the connecting

parts

221 and 221 on both sides of the steel antenna 220 is the same, so that the steel antenna 220 is stressed more uniformly when being connected with the frame 181. It is understood that the distance between the connecting element 221 and the connecting element 221 on both sides of the steel sheet antenna 220 is not necessarily the same, and the distance between the connecting element 221 and the connecting element 221 may be set according to the requirement, and is not limited herein.

The connecting member 221 is gradually widened from the steel sheet antenna 220 toward the extending direction of the frame 181. That is, the width of the connection position between the connection member 221 and the frame 181 is wider, so that the connection position between the connection member 221 and the frame 181 can be fixed at more positions, thereby improving the connection strength between the connection member 221 and the frame 181.

One end of the connecting piece 221, which is close to the frame, is provided with a hook. It should be noted that the hook is fixedly connected to the end of the connecting part 221 near the frame, or the steel antenna 220 may be formed in an arc shape extending toward the frame to form the hook.

In some embodiments, the feed point structure may be connected to the patch antenna 220 or may be integrally formed with the patch antenna 220. It should be noted that the feed point structure may be connected to the sheet antenna 220 and the radio frequency module in the electronic device by using a spring, a bridge, or the like. For the connection mode of the feeding point structure and the steel sheet antenna 220, the connection mode may be selected according to the requirement of the electronic device, and is not specifically limited in the embodiment of the present application.

In some embodiments, the patch antenna 220 includes a first side 222 and a second side 223 opposite the first side, the first side 222 being an upper edge, and the feed point structure being disposed on the first side 216. Of course, the feeding point structure may be disposed on the inner surface of the steel plate antenna 220, and the specific location where the feeding point structure is disposed on the steel plate antenna 220 is not particularly limited.

In some embodiments, the height of the bent portion of the patch antenna 220 and the feeding structure from the first side 222 is less than half of the height of the first side 222 and the second side 223 of the patch antenna 220. This may ensure the transmission performance of the antenna structure 210.

The feeding point structure passes through the frame 181 and extends out of the inner wall of the frame 181 to be connected with the radio frequency module in the electronic device. It should be noted that the feeding point structure passes through the frame 181, a mounting hole may be formed in the frame 181, so that the feeding point structure can pass through the frame 181 through the mounting hole, or a mounting groove may be formed in the frame 181, so that the feeding point structure is embedded in the mounting groove and passes through the frame 181, which is not limited to the above manner, and the feeding point structure may pass through the frame 181 when the feeding point structure and the frame 181 are molded together.
