An embodiment of the present disclosure provides an electronic apparatus including an apparatus body and a metal decoration. The device body comprises a back plate, and the metal decoration part can be arranged on the outer surface of the back plate, so that the metal decoration part can be used as a radiating body of the antenna to receive and transmit antenna signals. Because the metal decoration can set up the surface at the backplate, need not to occupy the space in electronic equipment's the equipment body, also do not occupy the region of the side frame of equipment, and the region that can set up the metal decoration on the backplate is great, can set up great size antenna, satisfies communication technology demands such as 5G, reserves more design space for the antenna that communication technology in the future needs set up simultaneously.

Fig. 1 schematically shows an application scenario of an electronic device according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of a scenario in which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.

As shown in fig. 1, the demands of users are increasing, for example, the display screen of the mobile phone is occupied as large as possible to improve the viewing effect, and the requirements of the mobile phone on the shooting definition and the scene restoration degree are also increasing. In order to meet various requirements of users, mobile phones are developed towards a direction of multiple cameras and a full screen. The mobile terminal has a small volume, and for example, in order to support multiple operating frequency bands as much as possible and reduce the occupation of the antenna on the internal space of the mobile phone, the mobile terminal has started to arrange the antenna on the metal frame of the mobile phone. However, as the display screen has a higher occupancy ratio, the metal bezel 2 becomes narrower. In addition, the metal frame 2 needs to have high mechanical strength to meet the structural strength requirement of the mobile phone. Therefore, the manner of the metal bezel 2 as the antenna of the mobile phone is limited by the appearance and the structural strength. For example, the metal frame is used as a sub6G antenna in a 5G antenna, and the metal frame is used as a sub6G antenna, so that the space for the 4G main diversity antenna and the GPS and WIFI antennas on the frame is occupied, and the metal frame of the mobile phone needs to be provided with a plurality of gaps (required antenna length, clearance area and the like), so that the structural strength of the metal frame is weakened and the metal frame is easy to break. For another example, the LDS antenna is used as the Sub6G antenna, which is limited in the usable range of the antenna on the mobile phone holder, and the material of the holder is a material that can be used for the spraying requirement of the Laser Direct Structuring (LDS), so that the cost is more expensive than that of the common plastic holder, resulting in higher popularization cost.

In addition, in order to improve the aesthetic degree of the mobile phone, the metal decoration 1 can be arranged on the back plate of the mobile phone, and in addition, the metal decoration can also have the functions of fixing mobile phone parts (such as fixing the camera 3), improving the mechanical strength (such as reinforcing ribs) of the back plate of the mobile phone and the like. In order to further promote the function integration level of the metal decoration piece, and considering that the metal decoration piece can be arranged on the insulator, the metal decoration piece on the back plate can have a large enough clearance area, so that the metal decoration piece is used as an antenna radiator of the electronic device to meet the requirement of the continuously developed communication technology on the antenna in the embodiment of the application.

In the left drawing of fig. 7, the metal part is connected with four top corners of the square metal ring for diagonal connection, so as to divide the long metal ring into four metal segments, and each metal segment can be used as a radiator of one antenna.

As shown in the right drawing of fig. 7, the metal decoration 20 includes a square metal ring, and the metal decoration 20 includes a metal segment and a metal part, wherein the metal part is connected to at least two sides of the square metal ring to divide the elongated metal ring into at least two metal segments, and the operating frequency bands of the antennas of the at least two metal segments are the same.

FIG. 8 schematically illustrates a schematic view of a metal trim piece according to another embodiment of the present disclosure.

As shown in fig. 8, the metal decoration 20 includes a circular metal ring, and the metal decoration 20 includes a metal segment and a metal part, wherein the metal part is connected to at least two points of the circular metal ring that are far away from each other, so as to divide the circular metal ring into at least two metal segments, and the operating frequency bands of the antennas of the at least two metal segments are the same. In fig. 8, the metal part is connected to two points of the circular metal ring which are far away from each other, so as to divide the circular metal ring into two metal segments, and each metal segment can be used as a radiator of one antenna. The metal plate is used as the grounding point 22, and the arrangement mode can refer to the above-mentioned embodiment, and is not described in detail here.

For the metal decoration 20 including the closed figure, it is necessary to divide the metal decoration 20 including the closed figure into radiators of a plurality of antennas by means of grounding. Accordingly, the operating frequency band of the at least one antenna is related to the equivalent length of the metal segment of the at least one antenna, which is related to the distance between the feeding point 21 and the grounding point 22 of the metal segment of the at least one antenna.

The operating frequency band of the antenna is explained below with reference to fig. 9. FIG. 9 schematically illustrates a schematic diagram of equivalent lengths of metal segments, according to an embodiment of the disclosure.

As shown in fig. 9, since the metal decoration 20 is divided into a plurality of metal segments as a radiator of the antenna by means of grounding, the operating frequency band of the antenna is related to the distance between the feeding point 21 and the grounding point 22.

The long metal loop shown in the upper diagram of fig. 9 is divided into two antennas by grounding, and the operating frequency band of each antenna is related to the equivalent length L of the metal segment of each antenna. The long metal ring in fig. 9 is used as a mount for the ornamental member and the lens group, and its equivalent length L is the distance between the feeding point 21 and the grounding point 22. For the case where there are two grounding points 22, the equivalent length L may be the distance between the feeding point 21 and the straight line constituted by the two grounding points 22.

It should be noted that, two, three, four or more cameras may be disposed on the mobile phone back panel 11 in the related art to improve the photographing effect, and accordingly, the length of the metal decoration 20 is long, for example, more than 10 mm, which is enough to meet the requirements of various working frequency bands. As shown in the upper diagram of fig. 9, the metal decoration 20 is divided into two sub6G antennas with equal length, so that two of 4 sub6G antennas required for 5G communication are implemented through the metal decoration 20, the space inside the terminal occupied by the antennas in the terminal of the 5G communication technology is reduced, and the design difficulty is reduced. In addition, since the metal decoration 20 is exposed and has a sufficiently large clearance area, it contributes to improving the antenna signal quality.

The square metal ring shown in the left drawing of fig. 9 may be divided into two antennas by one metal part, or may be divided into four antennas by two metal parts, and the equivalent length L is as shown in the left drawing of fig. 9.

The circular metal ring shown in the right diagram of fig. 9 can be divided into two antennas by one metal part, or can be divided into four antennas by two metal parts, and the equivalent length L is shown in the right diagram of fig. 9.

In one embodiment, the metal ornament 20 is used as a sub6G antenna, and the number of the rear camera of the mobile phone in the related art can be 2, 3 or 4. The occupied space is relatively large, and the metal decoration 20 for fixing the lens group is basically the most protruded area in the backward direction on the whole mobile phone, if the metal decoration is used for the design of the sub6G antenna, the relative clearance of the antenna is high, and the performance is relatively good.

The use of the rear metal trim 20 as a sub6G antenna may have the following effects:

first, the metal decoration 20 can be used as two sub6G antennas, and a grounding design is added in the middle, so that the two sub6G antennas have good isolation, and although the antennas are close to each other, the performance is reduced by influencing each other. In addition, the cost of the mobile phone shell can be saved, and materials meeting LDS spraying requirements are not needed to be used on a large area of the mobile phone support. In addition, the metal frame is only used for the main diversity antenna and the GPS and WIFI antennas, a plurality of gaps are not required to be formed, the design requirement of appearance integrity is met, the structural strength of the mobile phone cannot be weakened due to the plurality of gaps, and the risk of falling and breaking is reduced.

In other embodiments, the device body 10 further includes a metal frame, and the metal frame may be used as a radiator of at least a portion of an antenna of the electronic device.

Further, the electronic device may further include: and the working frequency band of the array antenna can be the same as or different from that of the antenna formed by the metal decorating part 20.

For example, the working frequency band of the array antenna is used for realizing the functions of the sub6G/4/3/2G antenna. In addition, the working frequency band of the array antenna can also be used for realizing the function of millimeter wave (mmWave).

Fig. 10 schematically shows a voltage standing wave ratio diagram of the antenna 1 according to an embodiment of the present disclosure.

The Voltage Standing Wave Ratio (VSWR) is used to detect the operating state of the antenna feeder system, the radio frequency connector and all radio frequency equipment connected to the base station. Too high VSWR can lead to dropped calls, high bit error rates, etc., and the resulting attenuation of transmit/receive power can lead to a reduction in cell coverage radius.

As shown in fig. 10, as the Frequency (Frequency) increases from 2.5GHz to 3.6GHz, the VSWR decreases, reaching a minimum of 1 or less, and the minimum at 3.6 GHz. The VSWR is lower than 10 within 3.4GHz to 4.5GHz and 4.9GHz to 6GHz, and is lower than 12 within 4.5GHz to 4.9GHz, so that the performance requirement of sub6G can be well met.

Fig. 11 schematically illustrates a voltage standing wave ratio diagram of the antenna 2 according to an embodiment of the present disclosure.

As shown in fig. 11, as the Frequency (Frequency) increases from 2.5GHz to 4GHz, the VSWR drops below 10 at a minimum of about 5 and the minimum at 4 GHz. The VSWR is lower than 20 within 3.3GHz to 5GHz, and the VSWR is lower than 10 within 3.5GHz to 4.5GHz, so that the performance requirement of sub6G is met.
