Fig. 2 is a second block diagram of the communication device 10 according to an embodiment, and referring to fig. 2, in this embodiment, the communication device 10 includes a middle frame 200 and an antenna unit 400.

Middle frame 200, including top rim 211, bottom rim 212, and first side rim 212 and second side rim 214 between top rim 211 and bottom rim 212; the antenna unit 400 includes a radiating element 410 provided with a feeding point a and a grounding point B, the radiating element 410 is disposed on the first side frame 212 and extends to the top frame 211 partially, the feeding point a is used for receiving a feeding signal, the grounding point B is used for connecting with a ground terminal, and the feeding point a and the grounding point B are respectively disposed on different frames; the feeding signal is used to excite the antenna unit 400 to generate a resonant mode at least covering the medium-high frequency range, so as to reduce the electric field intensity of the antenna unit 400 during operation.

For a description of the middle frame 200, refer to the above embodiment, and the description is omitted here.

The antenna unit 400 includes a radiating element 410 provided with a feeding point a and a grounding point B, the feeding point a is used for being connected with a feed source to receive a feeding signal, the grounding point B is used for being connected with a ground terminal, and the radiating element 410 generates a resonance mode under the excitation of the feeding signal of the feeding point a to transmit and receive an electromagnetic wave signal. Alternatively, the feed point a may be connected to the feed source by a feed trace, and the ground point B may be connected to the ground by a ground trace. The feed wire, the ground wire, the feed point A, the ground point B and the radiating element 410 form the antenna unit 400 together; the feed source may be disposed on the motherboard and the ground may be a ground plane on the motherboard. It will be appreciated that a matching circuit may also be provided between the feed point a and the feed source to adjust the impedance of the antenna element 400 to match the feed source (e.g., to tune to 75 ohms or 50 ohms), thereby improving the transceiving efficiency of the antenna element 400.

Wherein the resonant mode of the antenna unit 400 covers at least a mid-high frequency range, which may include a mid-high frequency range of LTE (long term evolution ), for example, frequency bands such as B1, B3, B40, B41, etc.; and a middle-high frequency range of NR (new radio) may be further included, for example, the frequency ranges of N1, N3, N40, N41, etc., where the frequency ranges span a middle frequency and a high frequency, which can avoid a decrease in radiation performance of the antenna caused by splitting the middle-high frequency, so that the antenna unit 400 has better OTA performance. Further alternatively, the resonant mode of the antenna unit 400 may also cover an ultra-high frequency range, for example, an N78 frequency range, so that the frequency range covered by the resonant mode includes 1.7G-3.8 Ghz, and may cover an intermediate frequency, a high frequency and an ultra-high frequency at the same time, so that the antenna unit 400 may receive and transmit electromagnetic wave signals in more frequency ranges, and further improve OTA performance.

The radiating element 410 is disposed on the first side frame 212 and extends to the top frame 211 partially, and the feeding point a and the grounding point B are respectively located on different frames, so that the antenna unit 400 is located at a corner of the first side frame 212 and the top frame 211 and is divided into two parts. On the one hand, since the antenna unit 400 is located at the corner of the middle frame 200, the distance between the corner and the main board is far greater than the distance between the side edge and the main board, so that the influence of devices on the main board on the antenna unit 400 at the corner in the radiation process is smaller, compared with the antenna unit 400 supporting the same standard and with the same frequency band, which is arranged in the waist region of the middle frame 200 in the related art, the antenna unit 400 in the middle-high frequency range is limited in space due to the size of the antenna unit 400 in the antenna region, which results in the reduction of the bandwidth of the middle-high frequency, the antenna unit 400 in the embodiment of the present utility model is advantageous in the first day, and the OTA performance is better; on the other hand, since the antenna unit 400 is divided into two parts, the electric field distribution area of the antenna unit 400 in the resonant mode is divided and dispersed on the first side and the front side (the first side and the front side refer to the related description below) of the communication device 10, so as to reduce the electric field intensity when the antenna unit 400 works, and therefore, SAR is also dispersed on the first side and the front side of the communication device 10, and the overall SAR value is reduced.

It should be noted that, referring to fig. 1 and fig. 2, the communication device 10 may be understood to include a front surface, a back surface, a first side surface, a second side surface, an upper side surface, and a lower side surface, where the front surface may be understood to be a surface on which the display screen 100 is located, and also a surface facing the Z-axis forward direction; the front surface is opposite to the back surface, and the back surface is the surface where the back cover 300 is positioned and is also the surface facing the Z axis reversely; the first side may be understood as the surface on which the first side frame 212 is located, and is also the surface facing the positive X-axis; the second side is the surface on which the second side frame 214 is located, and is also the surface facing the opposite direction of the X axis; the upper side face is a face facing the Y-axis forward direction, and the lower side face is a face facing the Y-axis reverse direction.

The communication device 10 provided in this embodiment includes a middle frame 200 and an antenna unit 400, where the middle frame 200 includes a top frame 211, a bottom frame 212, and a first side frame 212 and a first side frame 213 located between the top frame 211 and the bottom frame 212; the antenna unit 400 includes a radiating element 410 provided with a feeding point a and a grounding point B, the radiating element 410 is disposed on the first side frame 212 and extends to the top frame 211 partially, the feeding point a is used for receiving a feeding signal, the grounding point B is used for connecting with a ground terminal, and the feeding point a and the grounding point B are respectively disposed on different frames; the feeding signal is used to excite the antenna unit 400 to generate a resonant mode at least covering the medium-high frequency range, so as to reduce the electric field intensity of the antenna unit 400 during operation. On the one hand, the OTA performance of the antenna element 400 at the corner is better; on the other hand, since the antenna element 400 is divided, SAR will also be distributed over the first side and front of the communication device 10, reducing the overall SAR value. The communication device 10 can thus simultaneously ensure reduced SAR values and improved OTA performance of the antenna unit 400.

In one embodiment, please continue with fig. 2, the radiating element 410 includes a first radiating branch 411 and a second radiating branch 412, the first radiating branch 411 is located on a side of the first side frame 212 opposite to the first side frame 213, the second radiating branch 412 is located on a side of the top frame 211 opposite to the bottom frame 212, and a size of the first radiating branch 411 is larger than a size of the second radiating branch 412.

Thus, the antenna element 400 is divided into a first radiating stub 411 on the inner surface of the first side frame 212 and a second radiating stub 412 on the inner surface of the top frame 211, such that SAR hot spots will also be distributed on the first side and front of the communication device 10. Meanwhile, the size of the first radiation branch 411 is larger than that of the second radiation branch 412, and most of the antenna unit 400 is located on the side elevation where the first side frame 212 is located, so that the probability of shielding the antenna unit 400 due to holding when the communication device 10 is held can be reduced, and the OTA performance of the antenna unit 400 is further improved; while reducing SAR hot spots that the antenna element 400 disperses in the front during resonant modes.

In one embodiment, the feeding point a is located on the first radiating branch 411, and the grounding point B is located on the second radiating branch 412, so that, in the resonant mode excitation process of the antenna unit 400, current extends from the feeding point a of the first side frame 212 to the grounding point B of the top frame 211 for grounding, and the current strong point at the feeding point a is separated from the current strong point at the grounding point B by a distance to further disperse the electric field and current distribution, so as to achieve the effect of reducing the SAR value, and meanwhile, the radiation strong point is mainly distributed on the side elevation where the first side frame 212 is located, so that the OTA performance of the antenna unit 400 on the side elevation is further improved.

In one embodiment, the antenna unit 400 is an FPC antenna, the first radiating stub 411 is attached to the first side frame 212, and the second radiating stub 412 is attached to the top frame 211.

By selecting the FPC antenna and attaching the FPC antenna to the inner surfaces of the first side frame 212 and the top frame 211, the SAR value can be reduced, and the antenna unit 400 can be thinned, so that the occupied space of the antenna unit 400 in the communication device 10 is reduced, and the thinning of the communication device 10 is facilitated; meanwhile, the FPC antenna is more suitable for supporting more frequency bands, so as to reduce the cost and further improve the OTA performance of the antenna unit 400. Alternatively, the FPC antenna may be molded on the inner surfaces of the first side frame 212 and the top frame 211 by coating, printing, or the like. The extended trajectories of the first and

second radiation branches

411 and 412 include, but are not limited to, straight lines, bent lines, curved lines, etc.; the first radiation branches 411 and the second radiation branches 412 may be lines with uniform width on the extending track, or lines with gradual width change and unequal width such as widened regions.

In one embodiment, as shown in fig. 3, the communication device 10 may further include a rear cover 300, where the rear cover 300 is covered with the middle frame 200, and the rear cover 300 is provided with a rear camera hollow area 310 (fig. 3 shows a projection position of the rear camera hollow area 310 on a middle plate of the middle frame 200, and shows a relative position between the rear camera hollow area 310 and the battery); wherein the first radiation branch 411 and the second radiation branch 412 are disposed near the rear camera hollow 310.

The rear cover 300 is referred to the related description in the above embodiment, and will not be repeated here.

Wherein, the first radiation branch 411 and the second radiation branch 412 are close to the rear camera hollow area 310, and metal fittings and circuit devices of the rear camera hollow area 310 are fewer, the reverse vortex of the first radiation branch 411 and the second radiation branch 412 is weakened, and the effective magnetic field of the antenna unit 400 is further strengthened, thereby improving the communication performance of the antenna unit 400. In addition, the rear camera hollowed-out area 310 is a structure of the rear cover 300, and additional slotting and filling are not needed, so that the radiation performance of the antenna unit 400 can be obviously improved without affecting the appearance of the rear cover 300, and the communication quality of the communication device 10 is ensured.

In one embodiment, please continue to refer to fig. 2 and 3, as shown in fig. 2 and 3, the feeding point a and the grounding point B of the above embodiment are respectively located at two ends of the radiating element 410; the resonant modes include resonant modes of 1/2 wavelength.

When the feeding points a and the grounding points B are respectively located at the two ends of the radiating element 410, the antenna unit 400 can generate resonance modes with different wavelengths under the excitation of the feeding signal, and the resonance modes with different wavelengths can cover the frequency ranges of the medium-high frequency and the ultrahigh frequency related to the above embodiment. When the resonant mode is a 1/2 wavelength resonant mode, modes in different frequency ranges, such as N78 modes, excited by the 1/2 wavelength resonant mode, and SAR hot spots are 2 in total (as shown in fig. 4) and distributed at two ends of the antenna unit 400, and the dispersion degree of the SAR hot spots is higher than that of the SAR hot spots when the 1/4 wavelength resonant mode (as shown in fig. 5). Therefore, on the basis of the above embodiment, the SAR value can be further reduced by controlling the resonance mode of the antenna unit 400 to be the resonance mode of 1/2 wavelength.

In one embodiment, as shown in fig. 6, the feeding point a and the grounding point B are respectively located between two ends of the radiating element 410; the target resonant modes include a mixed resonant mode of 1/2 wavelength and 1/4 wavelength.

The two ends of the radiating element 410 extend to two sides at the positions of the feeding point a and the grounding point B, on one hand, the antenna caliber can be increased by extending the size of the radiating element 410, so that the intermediate frequency performance of the antenna unit 400 is greatly improved; on the other hand, after extension, the antenna unit 400 may also excite both a 1/4 wavelength mode and a 1/2 wavelength mode to form a hybrid resonant mode. By forming a hybrid resonant mode, the SAR hot spot can also be further dispersed to further reduce the SAR value.

In one embodiment, the target resonant mode also covers the ultra-high frequency range, as shown in fig. 7, and the communication device 10 further includes: tuning module 500.

The tuning module 500 is respectively connected to the ground point B and the ground terminal, and is configured to tune the resonant frequency point of the antenna unit 400, so that the antenna unit 400 operates in a target frequency range, where the target frequency range includes one of an intermediate frequency range, a high frequency range, and an ultra-high frequency range.

When the resonance mode of the antenna unit 400 covers the middle-high frequency range, the resonance action of the antenna unit 400 in any target frequency range in the middle-high frequency range can be switched through the tuning of the resonance frequency point of the antenna unit 400 by the tuning module 500, so that the resonance of the antenna unit 400 in different states can be matched with the coverage of the middle-high frequency full frequency range, and the OTA performance of the antenna unit 400 is improved; further optionally, the resonance mode of the antenna unit 400 may also cover an ultra-high frequency range, and tuning the resonance frequency point of the antenna unit 400 by the tuning module 500 can switch the resonance effect of the antenna unit 400 in any target frequency range of the intermediate-high frequency range and the ultra-high frequency range, so that the resonance of the antenna unit 400 in different states can be matched with the full frequency range covering the intermediate-high frequency range and the ultra-high frequency range, and further improve the OTA performance of the antenna unit 400.

In one embodiment, the tuning module 500 includes a plurality of tuning units, one end of each tuning unit is connected to the ground point B, and the other end of each tuning unit is switchably connected to the ground point, where tuning parameters of the plurality of tuning units are different.

The tuning parameters may include inductance values and/or capacitance values, and may further include resistance values, and the tuning units of different tuning parameters may include inductances and/or capacitances of different values, and may further include resistances of different values. By switching on/off states of the channels where the tuning units are located, current excited by the feed signal through the radiating element 410 returns to the ground through the tuning units with different tuning parameters, so that the electric length of the antenna unit 400 can be tuned, caliber tuning of the antenna unit 400 is realized, resonance effects in different frequency ranges are switched, and resonance in different states can be matched with full frequency bands covering medium-high frequency and ultrahigh frequency.

Optionally, the tuning module 500 further includes a tuning switch, through which the on-off state of the path where each tuning unit is located is switched, so as to tune the electrical length of the antenna unit 400, and implement aperture tuning of the antenna unit 400. Taking four tuning units and each tuning unit includes an inductance as an example, the tuning switch may be an SP4T switch, and multiple first ends of the SP4T switch may be respectively connected with the four tuning units correspondingly, and a second end of the SP4T switch is connected with the ground, so that the tuning function of the tuning module 500 can be achieved by switching the channel state of the channel where each tuning unit is located through the SP4T switch. Specifically, on different paths of the SP4T switch, inductors with different inductance values may be loaded respectively, so that by switching different paths, adjustment of the electrical length of the antenna unit 400 is achieved, so that the antenna unit 400 works in different target frequency ranges, and finally, the medium-frequency full-band, the high-frequency full-band and the ultra-high-frequency full-band can be covered. For example, when the path a is turned on, the inductance corresponding to the path a is turned on, and the resonant mode generated by the antenna unit 400 may be located in the frequency band a; when the channel B is turned on, the inductance corresponding to the channel B is turned on, so that the resonant mode generated by the antenna unit 400 may be located in the frequency band B. When the inductance values loaded on the path A and the path B are different, the frequency band A and the frequency band B are different. Illustratively, when the inductance parameter of path a is greater than the inductance parameter of path B, then the frequency band a in which the resonance generated by the antenna unit 400 occurs when switching from path a to path B may be shifted from a lower frequency band to a higher frequency band in which frequency band B is located.

In the above embodiment, the antenna unit 400 is not limited to the coverage adjustment of the high frequency range and the ultra-high frequency range in LTE and NR, but may cover the frequency ranges of WIFI, GPS L1, and the like, for example.

It should be noted that, in the above embodiment, the antenna unit 400 is based on the design of the communication device 10 in the case of being light and thin and the antenna arrangement space is limited. In other embodiments, if there is a sufficiently high distance between the back cover 300 and the middle plate, the radiating element 410 may also be disposed on the back cover 300 near the corner between the first side rim 212 and the top rim 211. The OTA performance of the antenna unit 400 may also be improved while reducing the SAR value.

The communication device 10 provided in the embodiment of the present application may further include other circuit components, taking the communication device 10 as a mobile phone for example: fig. 8 is a block diagram of a part of the structure of a mobile phone related to a communication device 1010 provided in an embodiment of the present application.
