As shown in fig. 4, the electronic device 10 provided in the embodiment of the present application further includes a ground plate 200, a radiator 300, a feed source (the feed source is not shown in the figure), and a radiation accessory 400.

In the present embodiment, the grounding plate 200 is used for carrying the radiator 300 and providing a grounding signal to ground the radiator 300, and the material of the grounding plate 200 may be a conductive material, such as a metal material, an alloy material, a conductive silica gel material, a graphite material, indium tin oxide, and the like.

In the present embodiment, the radiator 300 is disposed at one side of the ground plate 200 and is connected to the ground plate 200; the feed is electrically connected to the radiator 300 for feeding current to the radiator 300 to cause the radiator 300 to radiate a target signal.

The radiator 300 is used for receiving and transmitting a target signal, and the material of the radiator 300 may be a conductive material, such as a metal material, an alloy material, a conductive silica gel material, a graphite material, indium tin oxide, and the like. The target signal may be a signal having a target network system, for example, may be a 4G long term evolution (Long Term Evolution, LTE) signal, and may also include a 5G New Radio (NR) signal; or a radio frequency signal having a target frequency band, such as a low frequency, an intermediate frequency, a high frequency, etc. The specific type of target signal is not limited herein.

The radiator 300 is connected with a feed source and is used for feeding current through the feed source so as to excite a magnetic field and radiate a target signal outwards. Optionally, the electronic device 10 further comprises an antenna PCB (Printed Circuit Board ) on which the feed may be disposed. Alternatively, the feed may be a radio frequency chip or the like having means for providing an excitation signal. The specific feed source can be determined according to actual requirements, and the embodiment of the application is not limited.

The radiator 300 may be a radiation patch, and is completely attached to the ground plate 200; or may be partially disposed on the ground plate 200, and partially spaced from the ground plate 200 to form an open free end. When the radiator 300 is a radiation patch, the shape of the radiation patch is not limited and may be square, rectangular, polygonal, circular, etc.; when the radiator 300 has an open free end, the radiator 300 may be an IFA antenna, a T-shaped antenna, or the like.

Optionally, the radiator 300 has a ground return end and a free end, the ground return end is connected to the ground plate 200, the free end is spaced from the ground plate 200, and a feed end is provided between the ground return end and the free end of the radiator 300 to be connected to a feed source. The current of the radiator 300 is fed from the feed end, distributed on the radiator 300, and flows from the feed end to the free end and the return ground end respectively. Further alternatively, as shown in fig. 5 (100 in fig. 5 is a feed source), an F-shaped structure is formed among the ground return, the feed source and the radiator 300, and under the feed of the feed source current, the radiator 300 radiates the target signal in an IFA (Invented F Antenna, inverted F-shaped antenna) mode of a quarter wavelength. When the radiator 300 radiates the target signal in the IFA mode, the strongest current point in the radiator 300 is at the ground return end.

In this embodiment, the radiation fitting 400 is detachably disposed on a side of the radiator 300 facing away from the ground plate 200, and the radiation fitting 400 is used for radiating under the excitation of the radiator 300 to enhance the radiation efficiency of the target signal in the preset direction.

It is understood that the radiation fitting 400 may be fixed to the side of the radiator 300 facing away from the ground plate 200 or may be detachable from the radiator 300. Wherein, the space between the radiation fitting 400 and the radiator 300 is within a preset range; the detachment of the radiator 300 may be that the interval between the radiation fitting 400 and the radiator 300 is out of a preset range. The preset range may be a maximum range in which the radiation fitting 400 can radiate under the excitation of the radiator 300, and specific values may be set according to the material type, radiation mode, etc. of the radiation fitting 400 in practice, which is not limited herein.

Wherein it may be determined whether to fix the radiation fitting 400 on a side of the radiator 300 facing away from the ground plate 200 or to detach the radiation fitting 400 to be separated from the radiator 300 according to a communication environment in which the electronic device 10 is located or transceiving network information of the radiator 300. For example, the radiation fitting 400 may be fixed to the side of the radiator 300 facing away from the ground plate 200 when the electronic device 10 is in a weak signal environment such as a cell border, a deep building, an elevator, etc., and the radiation fitting 400 may be detached when the signal environment is strong. For example, when the network information transmitted and received by the radiator 300 does not satisfy the preset condition, for example, when the signal receiving strength of the radiator 300 is less than a certain threshold, the radiation fitting 400 may be fixed on the side of the radiator 300 facing away from the ground plane 200, and when the network information transmitted and received by the radiator 300 satisfies the preset condition, the radiation fitting 400 may be detached.

Wherein, the radiator 300 feeds in current under the excitation of the feed source, and the current is distributed on the surface of the radiator 300 to form an electric field, thereby exciting the radiation mode of the radiator 300; when the radiation fitting 400 is provided at one side of the radiator 300, the radiation fitting 400 feeds a current under the excitation of the radiator 300, and the current is distributed on the surface of the radiation fitting 400 to form an electric field, thereby exciting the radiation pattern of the radiation fitting 400. By setting the radiation efficiency of the radiation fitting 400 in the preset direction higher than the radiation efficiency in other directions, the radiation fitting 400 can enhance the radiation efficiency of the target signal in the preset direction, thereby improving the overall radiation efficiency of the electronic device 10.

Wherein the radiation fitting 400 is arranged at a side of the radiator 300 facing away from the ground plate 200, such that the radiation fitting 400 is arranged outwards with respect to the ground plate 200. Specifically, the radiation fitting 400 is disposed on a side of the radiator 300 facing away from the ground plate 200 and on an area that does not affect the radiation frequency band of the radiator 300, thereby ensuring that the radiation fitting 400 enhances the overall radiation efficiency of the electronic device 10 without affecting the radiation frequency band of the radiator 300. Optionally, the radiator 300 has a ground return end and a free end, the ground return end being connected to the ground plate 200, the free end being spaced apart from the ground plate 200; wherein: the radiation fitting 400 is located between the free end and the ground return end and near the ground return end. The free end is the weakest point of the current of the radiator 300, the ground return end is the strongest point of the current of the radiator 300, the ground return end of the radiator 300 corresponds to a short circuit, and the free end corresponds to an open circuit, so that the current distribution condition of the radiator 300 is that the current of the free end is weakest and the current of the ground return end is strongest under the excitation of the feed source, and therefore, when the radiation fitting 400 is positioned between the free end and the ground return end and close to the ground return end, namely, at the stronger point of the current, the radiation fitting 400 can be ensured to be excited by the radiator 300 to generate radiation, and the radiation frequency band of the radiator 300 is not affected.

Alternatively, as shown in fig. 5, the extension direction of the radiation fitting 400 is perpendicular to the radiator 300, and the extension direction is parallel to the preset direction. Wherein when the radiation fitting 400 is provided on one side of the radiator 300, the radiation fitting 400 feeds in a current under the excitation of the radiator 300, and the current flows from the radiator 300 to the radiation fitting 400 and is distributed on the surface of the radiation fitting 400. When the extension direction of the radiation fitting 400 is perpendicular to the radiator 300, current flows from the bottom of the radiation fitting 400 near the radiator 300 to the top of the radiator 300 extending, so that the direction of the current distributed on the radiation fitting 400 is perpendicular to the direction of the current distributed on the radiator 300, so that the direction of the electric field formed by the radiation fitting 400 is perpendicular to the radiator 300, effectively improving the overall radiation efficiency of the electronic device 10 and greatly changing the far field direction of the antenna.

Alternatively, the difference between the length of the radiation fitting 400 in the extending direction and the equivalent dielectric electromagnetic wave wavelength of the radiation fitting 400 is in a preset range. Specifically, the preset range approaches zero or a range equal to zero, so that the length of the radiation fitting 400 in the extending direction approaches equal to the equivalent medium electromagnetic wave wavelength to radiate effective electromagnetic waves under the excitation of the radiator 300.

Alternatively, the radiation fitting 400 may be a cube, a cylinder, or a solid block of other shapes, as long as the length of the radiation fitting 400 in the extending direction is approximately equal to the equivalent medium electromagnetic wave wavelength, and the dimensions in other directions may be set according to the design requirements of the actual ID (Industry Design). For example, as shown in fig. 6, the radiation fitting 400 is a cube, the height H of the radiation fitting 400 in the extending direction (i.e., the height of the cube) is about the equivalent medium electromagnetic wave wavelength, the length L of the bottom surface of the radiation fitting 400 on the side close to the radiator 300 is about 1/5 of the equivalent medium electromagnetic wave wavelength, and the width W is 1/8 of the equivalent medium electromagnetic wave wavelength.

Alternatively, as shown in fig. 7, the number of radiation fittings 400 may be plural (fig. 7 illustrates 2 as an example), and the plural radiation fittings 400 are disposed at intervals and the extending directions of the respective radiation fittings 400 are the same. Thus, the plurality of separate radiation fittings 400 can radiate externally under the excitation of the radiator 300 at the same time, further enhancing the radiation efficiency of the target signal in the preset direction, further improving the radiation efficiency of the electronic device 10 as a whole, and further changing the far field direction of the antenna. Wherein the plurality of radiation fittings 400 are not limited to the same size, each radiation fitting 400 may have a different size; the plurality of radiation fittings 400 may be arranged in an array, for example in a one-dimensional array.

Alternatively, the radiation fitting 400 is used to radiate in a dielectric resonator mode under the excitation of the radiator 300 to enhance the radiation efficiency of the target signal in a preset direction. When the radiation fitting 400 radiates in the dielectric resonator mode, the radiation fitting 400 forms an antenna of the dielectric resonator mode, and radiation can be performed through the surface of the radiation fitting 400, and since there is no conductor and surface wave loss and the dielectric itself loss is small, the radiation fitting 400 has high radiation efficiency, and the overall radiation efficiency of the electronic device 10 can be effectively improved. Further, when the radiation fitting 400 radiates in the dielectric resonator mode and the radiator 300 radiates in the quarter-wavelength mode, since the radiation patterns of the radiation fitting 400 and the radiator 300 are different, the electronic device 10 radiates in two modes, and the radiation bandwidth can be expanded. When the number of the radiation accessories 400 is plural, the plural radiation accessories 400 are excited to generate plural dielectric resonator modes, so that the overall radiation efficiency of the electronic device 10 can be further effectively improved, and the radiation bandwidth can be expanded.

Alternatively, the material of the radiation fitting 400 is a dielectric material with a high dielectric constant, such as glass, plastic, ceramic, etc. with a high dielectric constant, so that the radiation fitting 400 can radiate in a dielectric resonator mode under the excitation of the radiator 300. Further alternatively, the radiation fitting 400 has a relative permittivity greater than 10, such that the radiation fitting 400 forms an effective dielectric resonator antenna, effectively increasing the antenna efficiency of the electronic device 10 as a whole.

The following description will be made by taking the radiator 300 as an example of the communication capability of the first electronic device that does not include the radiation fitting 400 and the second electronic device that includes the radiation fitting 400 in the present embodiment (the radiation fitting 400 having a relative dielectric constant er of 20 as an example in the embodiment shown in fig. 8) as a low-frequency IFA antenna that operates at a resonance frequency point of 0.792 GHz:

referring to fig. 9-11, fig. 9, 10, and 11 are respectively a reflection coefficient curve, a radiation performance curve (wherein a solid line is a radiation efficiency curve, a dotted line is a system total efficiency curve), and a far field pattern of the first electronic device, and as can be seen from fig. 9, the reflection coefficient curve S11< -4dB (762-822 MHz) of the first electronic device; as can be seen from fig. 10, the total system efficiency of the first electronic device is-9.8 to-7.6 dB, and the average value is-8.7 dB. The overall system efficiency represents the communication performance of the electronic device, and better overall system efficiency enables a longer communication range and a faster communication data rate.

Referring to fig. 12-14, fig. 12, 13, and 14 are respectively a reflection coefficient curve, a radiation performance diagram, and a far field pattern of the second electronic device. As can be seen from fig. 8, after the radiation fitting 400 is disposed, a certain electric field is distributed on the radiation fitting 400 along the x-axis direction, and the electric field distributed on the mobile phone fitting has a great effect, so that the far-field pattern of the second electronic device is changed to a great extent: as can be seen from a comparison of fig. 14 and fig. 11, the far-field antenna pattern of the second electronic device is completely changed into a pattern of zero along the x-axis with respect to the first electronic device, thereby illustrating that the radiation pattern of the radiation fitting 400 occupies a large proportion in the overall radiation of the second electronic device, and the antenna efficiency can be effectively improved. As can be seen from fig. 12, after the radiation fitting 400 is set, the reflection coefficient curve S11< -4dB (765-845 MHz) of the second electronic device, the operating broadband becomes wider; as can be seen from FIG. 13, the total system efficiency of the second electronic device is-6.2 to-3.6 dB, the average value is-4.3 dB, and compared with the first electronic device, the total system efficiency of the second electronic device is improved by 4.5dB, and the improvement is very obvious.

Therefore, the radiation fitting 400 is used as an effective supplementary fitting of the electronic device 10, and is detachably disposed on the side of the radiator 300 away from the ground plate 200, so that the operating bandwidth of the radiator 300 is not deteriorated, but the communication performance of the electronic device 10 is greatly improved.

The radiation accessory 400 is used as an effective supplementary accessory of the electronic device 10, and is detachably arranged on one side of the radiator 300 away from the grounding plate 200, so that the antenna efficiency of the whole electronic device 10 is effectively increased under the excitation of the radiator 300, the communication range of the electronic device 10 is further, and the communication data rate is faster.

The middle frame 12 includes a frame 120 and a middle plate 130 connected to each other, the middle plate 130 is formed with a ground plate 200, and the frame 120 is formed with a radiator 300. Wherein, the middle plate 130 is formed with the ground plate 200, which may be understood that a partial area in the middle plate 130 is the ground plate 200, or the middle plate 130 is the ground plate 200; the formation of the rim 120 with the radiator 300 may be understood as a partial area on the rim being directly used as the radiator 300 or a break is provided on the rim to form the radiator 300.

The frame 120 includes a top frame 121 and a bottom frame 123 disposed opposite to each other, and a first side frame 122 and a second side frame 124 connected between the top frame 121 and the bottom frame 123, where at least one of the top frame 121, the bottom frame 123, the first side frame 122, and the second side frame 124 is formed with a radiator 300.

The concave portion is embedded on the frame 120, so that no additional auxiliary device is needed, the cost is saved, and the convenience of use is improved.

Alternatively, the radiation fitting 400 may be adsorbed on the frame 120 by an adsorber, where the adsorber is located on a region of the frame 120 where the radiator 300 is not located, and the adsorber detachably fixes the radiation fitting 400 on a side of the radiator 300 facing away from the ground plate 200 by adsorption.

Alternatively, the radiation fitting 400 may also be detachably provided on the side of the radiator 300 facing away from the ground plate 200 by a movable connection such as a spring. For example, one end of the movable connection piece is disposed on the frame 120, and the other end is mechanically connected with the radiation fitting 400, so that the movable connection piece is controlled by the control circuit or manually controlled by a user to move to drive the radiation fitting 400 and the radiator 300 to move relatively, so as to control the distance between the radiation fitting 400 and the radiator 300 to be in or out of a preset range.

When the radiation fitting 400 is fitted to the housing 20 through the groove or the slit, the radiation fitting 400 may be configured to be permanently fixed to the housing 20 or may be configured to be detachably provided to the housing 20. The housing 20 is detachably disposed on the middle frame 12 of the electronic device 10, and it is understood that the housing 20 is only disposed on the middle frame 12, and it is also understood that the cover assembly 13 is disposed on the middle frame 12 of the electronic device 10 and simultaneously wraps the electronic device 10 (please refer to fig. 1-3 for assistance).

Optionally, the prompting circuit may further generate a disassembly signal when the network information meets a preset condition, and the auxiliary control element controls the distance between the radiation fitting 400 and the radiator 300 to exceed a preset range according to the disassembly signal, so as to separate the radiation fitting 400 from the radiator 300. The preset range is referred to the related description in the above embodiment, and will not be repeated here.

The network information may include, among other things, raw and processed information associated with radio performance metrics of the radiator 300 when transceiving the target signal, such as signal strength, received power, reference signal received power (Reference Signal Receiving Power, RSRP), received signal strength (Received Signal Strength Indicator, RSSI), signal to noise ratio (Signal to Noise Ratio, SNR), carrier-to-interference-and-noise ratio (Carrier to Interference plus Noise Ratio, RS-CINR), frame error rate, bit error rate, reference signal received quality (Reference signal reception quality, RSRQ), etc.

Taking the network information as an example of the received signal strength, if the signal strength of the low-frequency signal transmitted and received by the radiator 300 is lower than the preset threshold value in the preset time period, a prompt signal is generated to prompt the target object to locate the radiation accessory 400 on the electronic device 10. The magnitude of the preset threshold value can be set according to requirements.

The electronic device 10 provided in this embodiment includes the ground plate 200, the radiator 300, the feed source, the radiation fitting 400 and the middle frame 12 described in the above embodiments, where the middle frame 12 includes the border 120 and the middle plate 130 that are connected to each other, the middle plate 130 is formed with the ground plate 200, and the border 120 is formed with the radiator 300. Because the radiation fitting 400 is used as an effective supplementary fitting in the electronic device 10, and is detachably arranged on the side, away from the grounding plate 200, of the radiator 300, the antenna efficiency of the whole electronic device 10 is effectively increased under the excitation of the radiator 300, so that the electronic device 10 has higher signal transceiving performance, longer communication range and faster communication data rate.

As further illustrated in fig. 18, and as an example of the electronic device 10 as a cellular telephone 30, the cellular telephone 30 may include a memory 21 (which optionally includes one or more computer readable storage media), a processor 22, a peripheral interface 23, a radio frequency system 24, and an input/output (I/O) subsystem 26, as shown in fig. 18. These components optionally communicate via one or more communication buses or signal lines 29. Those skilled in the art will appreciate that the handset 11 shown in fig. 18 is not limiting and may include more or fewer components than shown, or may be combined with certain components, or may have a different arrangement of components. The various components shown in the figures are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application specific integrated circuits.

Memory 21 optionally includes high-speed random access memory, and also optionally includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Illustratively, the software components stored in the memory 21 include an operating system 211, a communication module (or instruction set) 212, a Global Positioning System (GPS) module (or instruction set) 213, and the like.

The processor 22 and other control circuitry, such as control circuitry in the radio frequency system 24, may be used to control the operation of the handset 11. The processor 22 may be based on one or more microprocessors, microcontrollers, digital signal processors, baseband processors, power management units, audio codec chips, application specific integrated circuits, and the like.

The processor 22 may be configured to implement a control algorithm that controls the use of the antenna in the handset 11. The processor 22 may also issue control commands or the like for controlling the various switches in the radio frequency system 24.

The I/O subsystem 26 couples input/output peripheral devices on the handset 11, such as keypads and other input control devices, to the peripheral interface 23. The I/O subsystem 26 optionally includes a touch screen, keys, tone generator, accelerometer (motion sensor), ambient light sensor and other sensors, light emitting diodes, and other status indicators, data ports, etc. Illustratively, a user may control the operation of the handset 11 by supplying commands via the I/O subsystem 26, and may use the output resources of the I/O subsystem 26 to receive status information and other outputs from the handset 11. For example, a user may activate the handset or deactivate the handset by pressing button 261.

The radio frequency system 24 may include a radiator and a radiating fitting in any of the embodiments described above.
