Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Fig. 1 is a first schematic structural diagram of a terminal device according to an exemplary embodiment. As shown in fig. 1, the terminal device includes at least:

a curved screen having a planar area and a curved area 101 located at an edge of the planar area;

the conductive frame is in contact with the edge of the curved surface area; the conductive frame has at least one groove, and the conductive frame with the groove is an antenna radiator 102 of the terminal device.

The terminal device can be a mobile terminal or a wearable electronic device. The mobile terminal comprises a smart phone, a notebook and a tablet computer; the wearable electronic device includes a smart watch, embodiments of the present disclosure are not limited.

The curved screen is a screen having a curvature, and includes: a planar area and a curved area. The flat area and the curved area may both be used to display information. The information displayed by the plane area and the information displayed by the curved area jointly form a display picture of the terminal equipment. Compared with a plane screen, the curved screen has a better three-dimensional display effect and can improve the sensory experience.

It should be noted that the curvature of the curved screen is positively correlated to the size of the curved area. For example, the size of the curved surface region with a large curvature is larger than that of the curved surface region with a small curvature.

In the embodiment of the present disclosure, the curved surface area is located at the edge of the planar area. The shape of the planar area includes, but is not limited to, rectangular or circular. When the planar area is rectangular, the curved area can be located on the edges of two opposite sides in the rectangle; alternatively, it may be located on the edges of four sides in a rectangle. When the planar area is circular, the curved area may be located on the circular edge.

It should be noted that the curved screen is overlaid on at least two adjacent surfaces of the terminal device. When the curved surface area is positioned on the edges of two opposite sides in the rectangle, the curved surface screen covers three adjacent surfaces of the terminal equipment; when the curved area is located on the four side edges of the rectangle, the curved screen is overlaid on five adjacent surfaces of the terminal device.

In the embodiment of the disclosure, the curved surface area of the curved surface screen and the conductive frame jointly form the side surface of the terminal device. The side surface may be one side surface of the terminal device, or may be multiple side surfaces of the terminal device, and the embodiments of the present disclosure are not limited. The side face is an adjacent side face of the side face where the camera is located in the terminal equipment.

The conductive frame is a frame body which surrounds the terminal equipment and is exposed outside.

In the embodiment of the disclosure, the conductive frame is in contact with the edge of the curved surface region but does not overlap. Therefore, when the curved screen is arranged on the terminal equipment, the curved area of the curved screen cannot be wrapped or the conductive frame cannot be shielded.

In some embodiments, all four surfaces of the conductive bezel are in contact with the curved surface region.

In other embodiments, two opposite surfaces of the conductive bezel are in contact with the curved surface region.

It should be noted that the conductive frame may be a rectangular frame. Two opposite surfaces in the conductive frame are in contact with the curved surface area, and the conductive frame can comprise: the surfaces of the two long sides oppositely arranged in the conductive frame are in contact with the curved surface area; alternatively, the method can also comprise the following steps: the surfaces of the two short sides oppositely arranged in the conductive frame are in contact with the curved surface area, and the embodiment of the disclosure is not limited.

In an embodiment of the present disclosure, the conductive frame with the at least one groove is an antenna radiator of the terminal device. That is, the electrical length of the antenna radiator is the sum of the groove wall and the groove bottom of the groove, and is not directly the length of the conductive frame. In this manner, the conductive bezel having at least one slot forms an antenna radiator that can increase the electrical length of the antenna radiator relative to an elongated antenna radiator.

The antenna radiator may be a conductor formed of a material such as a metal or an alloy. The antenna radiator can be used for radiating wireless signals of different frequency bands. For example, the antenna radiator may radiate a radio signal of 2G band; or, a wireless signal of a 3G frequency band; or, wireless signals in 4G frequency band; or, a wireless signal in a 5G frequency band, which is not limited by the embodiments of the present disclosure.

Fig. 2 is a top view and a side view of a terminal device having a flat screen. Fig. 3 is a top view and a side view of a terminal device having a curved screen. As shown in fig. 2 and 3, the whole section of the conductive frame of the terminal device in the extending direction is an antenna radiator 201. When the curved screen 202 is disposed on the terminal device, the curved area of the curved screen 202 covers the frame, and further, most of the antenna radiator 201 is wrapped. As such, antenna performance may be degraded when the antenna radiator radiates a wireless signal. And, the larger the curved surface area is, the larger the range of wrapping the antenna radiator is, and the larger the antenna performance decline range is.

Fig. 4 is a top side view of the antenna radiator 102 in an embodiment of the present disclosure. Fig. 5 is a top view of the conductive frame after contacting the curved surface region. As shown in fig. 4 and 5, the antenna radiator 102 is in contact with the curved area 101, which does not wrap or shield the antenna radiator, and the antenna radiator is exposed outside the terminal device.

Based on this, the embodiment of the present disclosure brings the curved surface region into contact with the edge of the conductive bezel, and uses at least a portion of the conductive bezel as an antenna radiator. That is to say, this disclosed embodiment sets up the antenna radiator on the electrically conductive frame with curved surface region contact, and this curved surface region can not overlap with the antenna radiator, consequently can reduce the condition that the antenna radiator is covered by curved surface region for the radiant energy of antenna radiator can radiate away to the greatest extent, has improved antenna radiation efficiency. Moreover, compared with the strip-shaped antenna radiator, the antenna radiator formed by the conductive frame with the groove can increase the electrical length of the antenna radiator, so that the lowest frequency of the terminal device for receiving and transmitting wireless signals can be increased, and the terminal device can receive and transmit wireless signals of more frequency bands. Meanwhile, the size of the antenna radiator cannot be increased under the condition that the electrical length of the antenna radiator is increased, and the miniaturization design of the antenna can be realized.

Fig. 6 is a schematic diagram illustrating a comparison of radiation efficiency of antenna radiators according to an embodiment of the present disclosure. Fig. 7 is a schematic diagram illustrating a standing wave comparison of an antenna radiator according to an embodiment of the present disclosure. Fig. 8 is a comparison of the total efficiency of the antenna radiator in the embodiments of the present disclosure. As shown in fig. 6, in the frequency band of 1.7GHz to 2.7GHz, the slot and the antenna radiator of the prior art are completely wrapped by the curved screen, and the energy of the wrapped antenna radiator cannot be radiated outside the terminal device, so that the simulated radiation efficiency of the antenna radiator in the embodiment of the present disclosure is 3.4dB to 4.4dB higher than the radiation efficiency of the antenna radiator wrapped by the curved screen. As shown in fig. 7, simulation shows that the radiation efficiency of the antenna radiator in the embodiment of the present disclosure is better than the standing wave of the conventional antenna radiator wrapped by the curved screen. As shown in fig. 8, in the two frequency bands of the frequency band 3 and the frequency band 7, the total efficiency of the antenna radiator in the embodiment of the present disclosure is respectively 4.4dB and 3.3dB higher than the total efficiency of the antenna radiator in the prior art after being wrapped by the curved screen, and thus the performance of the antenna radiator in the embodiment of the present disclosure is better.

In some embodiments, as shown in fig. 9, the antenna radiator has a first end 102a and a second end 102b disposed opposite the first end;

the first end 102a is connected with a ground wire;

the second end 102b is formed with a slit;

wherein the gap is filled with an insulating material.

In the embodiment of the present disclosure, the first end of the antenna radiator is connected to the ground line, and is configured to form a loop to return the high-frequency current in the antenna radiator to the ground.

A slot is formed at the second end of the antenna radiator. The slot separates the conductors of the antenna radiator. The slot enables the antenna radiator to generate resonance and can receive and transmit wireless signals.

It should be noted that the width of the gap can be set according to actual needs. For example, the width of the slot may be half the wavelength of the wireless signal; alternatively, the width of the gap may range from 0.5 mm to 2 mm, and embodiments of the present disclosure are not limited.

The shape of the gap can be set according to actual needs. For example, the slit may be an elongated slit, an L-shaped slit, or a circular slit, and the embodiments of the present disclosure are not limited thereto.

Illustratively, the insulating material includes, but is not limited to, a material formed of plastic, rubber, or ceramic.

In the embodiment of the disclosure, the terminal device includes a smart phone, and the gap may be set at the top of the smart phone or at the bottom of the smart phone. Therefore, in the process of using the smart phone, the situation of blocking gaps caused by holding the smart phone by hand can be reduced, and then the wireless signals can be radiated outside the terminal equipment to the maximum extent.

In some embodiments, the antenna radiator may further include: the first sub radiator and the second sub radiator with a gap with the first sub radiator. The length of the second sub-radiator may be longer than that of the first sub-radiator, or may be shorter than that of the first sub-radiator, which is not limited in the present disclosure. Therefore, the coverage frequency band can be effectively increased, and the shorter the length is, the higher the coverage frequency of the increased frequency band is.

In an embodiment of the disclosure, a terminal device includes an antenna feed point. The antenna feed point may be disposed on the first sub-radiator or the second sub-radiator, and may also be disposed on the first sub-radiator and the second sub-radiator, respectively, which is not limited in this disclosure. It should be noted that, the antenna feed points are respectively arranged on the first sub-radiator and the second sub-radiator, so that a dual-antenna structure can be implemented, and further, the terminal device can implement coverage of more frequency bands.

The first sub radiator and the second sub radiator may be provided with grooves. So, all set up the recess through on first sub-irradiator and second sub-irradiator, can effectively increase the current circulation route, increase electric length promptly, and then can further increase the minimum frequency that terminal equipment received and dispatched wireless signal.

In some embodiments, a distance from the first end to the second end of the antenna radiator is inversely related to a lowest frequency at which the antenna radiator transceives the wireless signal.

In the embodiment of the present disclosure, the lowest frequency of the antenna radiator for receiving and transmitting the wireless signal is the lowest frequency in the corresponding radiation frequency band of the antenna radiator when the radiation efficiency reaches the standard.

It should be noted that the distance from the first end to the second end of the antenna radiator may be a first distance or a second distance smaller than the first distance, where the lowest frequency of the antenna radiator at the first distance for receiving and transmitting the wireless signal is greater than the lowest frequency of the antenna radiator at the second distance for receiving and transmitting the wireless signal.

The antenna radiator may be an inverted F antenna radiator, for example.

In some embodiments, the terminal device comprises: an antenna feed point located on the antenna radiator. The position of the antenna feed point on the antenna radiator may be set according to actual needs, and the embodiments of the present disclosure are not limited. It should be noted that, when the antenna feeding point is fed, the antenna radiator resonates, the first end and the second end of the antenna radiator generate a quarter eigenmode, and the monopole mode is generated from the antenna feeding point to the second end, and the antenna efficiencies of the two modes are higher. Therefore, when the antenna feeding point is close to the second end, the radiation frequency of the corresponding Monopole antenna is also high. In the embodiment of the present disclosure, the antenna feeding point is configured to output a first electrical signal to the antenna radiator, so that the antenna radiator radiates a wireless signal under excitation of the first electrical signal, and may be further configured to output a second electrical signal obtained by conversion by the antenna radiator.

Taking the first electrical signal as an example, when the antenna radiator is fed, the antenna radiator is excited to generate resonance, the generated resonance has higher radiation efficiency in a quarter eigenmode and a monopole mode, and the frequency of the monopole mode is higher than that of the quarter eigenmode. Thus, two frequency band coverages with high radiation efficiency can be realized. Similarly, the antenna radiator can also realize the coverage of two frequency bands for the second electric signal.

In the embodiment of the present disclosure, the terminal device further includes a radio frequency front end module and a feeder connected between the radio frequency front end module and the antenna feed point. When radiating a wireless signal, the feeder outputs a first electrical signal generated by the radio frequency front end module to the antenna feed point, and the antenna feed point outputs the first electrical signal to the antenna radiator. When receiving the wireless signal, the antenna radiator converts the received wireless signal into a second electrical signal, and the antenna radiator outputs the second electrical signal to the radio frequency front end module through the antenna feed point and the feeder line, so that subsequent processing such as receiving the wireless signal and decoding the signal is realized.

It should be noted that the radio frequency front end module includes a first amplifier, an antenna switch, a filtering component, a duplexer, and a second amplifier. The first amplifier is used for amplifying the electric signal in the signal output channel. The antenna switch is used for realizing the switching between the receiving of the electric signals and the transmitting of the electric signals and the switching between different frequency bands of the antenna. The filter is used for filtering signals outside the specific frequency band through the signals of the specific frequency band. The duplexer is used for isolating the transmitted electric signal and the received electric signal, so that the antenna can normally work when receiving and transmitting wireless signals simultaneously. The second amplifier is used for realizing the electric signal amplification of the signal receiving channel. Therefore, the radio frequency front end module can receive and transmit electric signals, and the antenna radiating body can better receive and transmit wireless signals.

In some embodiments, the antenna radiator is C-shaped, E-shaped, or F-shaped.

In other embodiments, the antenna radiator may also be U-shaped, L-shaped, or N-shaped.

It should be noted that the antenna radiator may be bent, or may also be zigzag or wavy in any of the above embodiments, and the embodiments of the present disclosure are not limited.

In some embodiments, as shown in fig. 10 and 11, the antenna radiator 102 includes: the device comprises a first side edge and a second side edge opposite to the first side edge;

the first side edge is connected with the curved surface area 101;

the antenna radiator 102 is recessed from the second side toward the first side to form the groove 102 c.

The antenna radiator is in direct contact with the curved surface area. That is, in the case of setting the width of the antenna radiator, the width of the antenna radiator may be set to the width of the entire conductive bezel. Therefore, the conductive area can be increased under the condition of increasing the width of the antenna radiator, the radiation area of the antenna is increased, and the radiation efficiency of the antenna is further improved.

The antenna radiator is recessed from the second side to the first side to form at least one groove. The groove is arranged on the second side edge, and the depth of the groove is smaller than the width of the conductive frame.

It should be noted that the shape of the groove in the embodiments of the present disclosure can be arbitrarily set according to actual needs. For example, the groove may be configured as a V-shaped groove or a U-shaped groove, and the embodiments of the present disclosure are not limited.

In the embodiment of the disclosure, on the basis that the number of the grooves is the same, the shapes of the grooves are different, and the effective electrical lengths of the antenna radiators are also different. For example, when the antenna radiator includes a groove, and the groove is a V-shaped groove, the effective electrical length of the antenna radiator may be an effective electrical length corresponding to the V-shape; when the antenna radiator comprises a groove which is a U-shaped groove, the effective electrical length of the antenna radiator can be the effective electrical length corresponding to the U shape.

It can be understood that, through the shape of the groove, antenna radiators with different electrical lengths can be formed, so that antennas with different effective electrical lengths can be obtained, and the flexibility of the antenna radiators is improved.

In some embodiments, the number of slots is positively correlated to the electrical length of the antenna radiator. For example, the electrical length of the antenna radiator with the large number of slots is greater than the electrical length of the antenna radiator with the small number of slots.

In other embodiments, the depth of the groove is positively correlated to the electrical length of the antenna radiator.

In the case of the same number of grooves, the deeper the groove depth, the longer the groove wall of the corresponding groove, and thus the longer the electrical length of the antenna radiator. Therefore, on the basis that the number of the grooves is the same, the electrical length of the antenna radiator can be increased by increasing the depth of the grooves, and another implementation mode is provided for increasing the electrical length of the antenna radiator.

As shown in fig. 12, the intersection point between the smith curve of the antenna radiator and the solid axis of the smith chart is the antenna characteristic pattern frequency point, and it can be seen from fig. 12 that the first intersection point on the right side of the smith chart of the strip antenna radiator is at 1.84Ghz, and the first intersection point on the right side of the smith chart of the antenna radiator with the groove is at 1.65 Ghz. The first intersection point on the left side of the smith chart of the elongated antenna radiator is at 1.84Ghz and the first intersection point on the left side of the smith chart of the antenna radiator with the recess is at 1.65 Ghz. Therefore, through verification, the effective electrical length of the antenna can be increased by the antenna radiator with the groove, the current path is lengthened, the efficiency of the terminal device for receiving and sending the wireless signals can be increased, the lowest frequency of the terminal device for receiving and sending the wireless signals can be reduced, and the terminal device can receive and send the wireless signals of more frequency bands.

In some embodiments, the terminal device further comprises:

the antenna radiator extends onto the back shell.

In an embodiment of the present disclosure, the antenna radiator includes at least one conductive arm disposed at an interval. The extension of the antenna radiator onto the back shell comprises: at least one conductive arm of the antenna radiator extends onto the back shell. For example, one conductive arm of the antenna radiator extends onto the back shell; alternatively, the two conductive arms of the antenna radiator extend onto the back shell, and the embodiments of the present disclosure are not limited thereto.

It is understood that the antenna radiator in the embodiments of the present disclosure may be located not only on the conductive bezel, but also on the conductive bezel and the back shell. Therefore, the area of the antenna radiator can be increased, and the radiation efficiency can be improved and the lowest frequency of the antenna radiator for receiving and transmitting the wireless signals can be reduced.

the curved screen is arranged on the middle frame;

The middle frame is a bearing body of each functional module in the terminal equipment. The middle frame is provided with a plurality of intervals, and the functional module is positioned in the accommodating space in the intervals.

The curved screen includes a flat area and a curved area. This curved surface screen is installed on the center, includes: the plane area of the curved screen is arranged on the middle frame.

The antenna radiator extends to the upper part of the back shell and is parallel to the middle frame. The gap formed by the second end of the antenna radiator in the terminal device can be positioned on the back shell, and the gap positioned on the back shell is parallel to the middle frame.

It is understood that the antenna radiator in the embodiments of the present disclosure may be located not only on the conductive bezel, but also on both the conductive bezel and the back shell. Therefore, the area of the antenna radiator can be increased, and the radiation efficiency can be improved and the lowest frequency of the antenna radiator for receiving and transmitting the wireless signals can be reduced.
