Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in itself. Thus, "module", "component" or "unit" may be used mixedly.

The terminal may be implemented in various forms. For example, the terminal described in the present invention may include a mobile terminal such as a mobile phone, a tablet computer, a notebook computer, a palmtop computer, a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a navigation device, a wearable device, a smart band, and a fixed terminal such as a Digital TV, a desktop computer, and the like. In the embodiment of the present invention, a mobile terminal will be described as an example, and those skilled in the art will appreciate that the configuration according to the embodiment of the present invention can be applied to a fixed type terminal in addition to elements particularly used for moving purposes.

It can be understood that, when two rf signals of the mobile terminal belong to the same frequency, the two rf signals cannot be distinguished from each other on the rf circuit, and one of the two rf signals cannot be filtered out, so that the same frequency of the signals will cause great interference to the circuit performance. Conventionally, when a radio frequency signal is in a frequency band concurrent mode, that is, when the radio frequency signals of two frequency bands work simultaneously and a harmonic frequency of one frequency band is in a frequency band of the other frequency band, signal interference is caused, which is a problem that engineers need to solve urgently and is also a problem that engineers pay attention to.

At present, the above problems become more prominent, especially, the introduction of north american B14 (788-798 MHz) frequency band (the second harmonic frequency of the frequency band is closer to GPS (1575.42MHz)) and the use of Auto-Diversity (ASDIV) antenna switching System (taking a smart phone as an example, before the ASDIV is used, a transmitting antenna and a Global Positioning System (GPS) antenna are respectively located at the bottom and the top, and after the ASDIV is used, the transmitting antenna and the GPS antenna are both located at the top), so that the isolation between the GPS antenna and the transmitting antenna is further reduced, and the above problems become more prominent; in addition, for Carrier Aggregation (CA) scenarios and the use of subsequent 5G frequency bands, the problem of signal interference caused by frequency band concurrency is also made more prominent.

It should be noted that, since the radio frequency bands themselves are different, it is impossible for signals of two frequency bands to be at the same frequency point, so that a frequency-doubled signal generated by a harmonic becomes a main object of interference. Since the frequency of the harmonic may be in the frequency band of other rf frequency bands, and since the frequency value of the rf is not an absolute frequency, when two frequencies are very close, the two frequencies can interfere with each other due to the out-of-band signal of the frequencies.

It should be further noted that the frequency band concurrence refers to a scenario in which radio frequency signals of two frequency bands work simultaneously, and generally refers to a CA scenario of a main radio frequency signal, that is, a scenario in which radio frequency signals of two main radio frequency bands work simultaneously, or a scenario in which a main radio frequency signal and a GPS or WIFI signal are transmitted simultaneously. In addition, the antenna isolation refers to the ratio of a signal transmitted by one antenna and received by the other antenna to the signal of the transmitting antenna; the greater the isolation, the less likely signal crosstalk will occur between the two antennas.

For example, when a harmonic signal of a transmission signal between the main radio frequency band and the WIFI frequency band, between the main radio frequency band and the GPS frequency band, or between the main radio frequency band and the main radio frequency band, that is, a second harmonic signal and a third harmonic signal, is just in a band or a band edge of another reception signal, the transmission signal may generate a relatively serious interference to the reception signal at this time. Specifically, the following four concurrency scenarios are taken as examples:

(a) the third harmonic signal of the B12 frequency band is within the B4 frequency band;

(b) b26, the third harmonic signal of the frequency band is within the frequency band of the WIFI frequency band;

(c) the second harmonic signal of the B14 frequency band is within the frequency band of the GPS frequency band;

(d) due to the use of an uplink CA scene, more interference frequency bands can be caused by the mixing of two signals and the mixing of harmonic signals; for example, the transmission frequency of the B42 band is 3400-3600 MHz, and the transmission intermodulation product of the transmission frequency of the B2 band 1850-1910 MHz will be in the frequency band of GPS (1575.42MHz), so if there is a concurrent scenario between B42 and B2, i.e., constituting an uplink CA, the GPS signal will be interfered.

Generally, the existing solution filters out the higher harmonic signals by using a low-pass filter, but the filter cannot be used for the following situation; that is, the rf circuit itself supports multiple frequency bands, and when the harmonic signal of a certain frequency band is close to another frequency band, the filter cannot be used, and the interference in this case becomes a problem that engineers are very troublesome.

For example, referring to fig. 1, a schematic diagram of a tuning standing wave distribution applied to an antenna system according to an embodiment of the present invention is shown, in fig. 1, the antenna system supports low-frequency bands B13(777 to 787MHz), B14(788 to 798MHz), intermediate-frequency bands B4(1710 to 2155MHz), and GPS (1575.42MHz) and WIFI; b13, B14 and B4 share a transmitting antenna, a GPS single antenna is adopted, a scene of simultaneous use exists in B13, B14 and B4 and a GPS, but B13, B14 and B4 do not work simultaneously, second harmonics of B13 and B14 are very close to a GPS frequency and easily form interference, B4 is close to the GPS frequency, and when the B4 efficiency is high on the antenna, the GPS efficiency is high; that is to say, because the radio frequencies B13 and B14 have a concurrent scene with the GPS, and the second harmonic signals of B13 and B14 fall on the band edge of the GPS frequency band, when the radio frequencies B13 and B14 are concurrent with the GPS, the second harmonic signals of B13 and B14 are on the band edge of the GPS frequency band, which causes the problem that the transmitting antenna has an interfered frequency point, i.e., an efficiency point of the GPS, i.e., poor isolation from the GPS antenna, and the transmitting antenna cannot suppress interference caused by the second harmonic signals of B13 and B14 when the transmitting antenna is operated being transmitted from the transmitting antenna and received by the GPS antenna, resulting in inaccurate GPS positioning. In addition, due to the space limitation of the mobile terminal, the main rf signals such as B13, B14, and B4 are generally transmitted and received by one transmitting antenna, i.e. the several frequency bands are co-antenna, but these frequency bands do not work simultaneously. As can be seen from fig. 1, due to the presence of B4, a deep standing wave must exist at 1.71GHz in the main antenna, and since the GPS frequency point is relatively close to the frequency point of B4, the GPS frequency point also has a standing wave on the antenna, so that the second harmonic signals generated by the radio frequency circuit in the B13 and B14 frequency bands are more easily transmitted from the main antenna, thereby creating a risk of GPS interference.

Several other concurrency scenarios are described below:

harmonic signals of the main radio frequency interfere with WIFI signals, such as: a third harmonic signal of a B26 frequency band between B26 (814-849 MHz) and WIFI (2400-2483 MHz) is within a frequency band of a WIFI frequency band, so that when 2.4G frequency bands such as B41 and B7 exist in a radio frequency circuit at the same time, a filter cannot be used; at this time, if a concurrent scene exists between B26 and WIFI, the sensitivity of WIFI may be reduced, so that the WIFI rate is reduced, and the user experience is affected.

The harmonic interference signal of the main radio frequency and the main radio frequency, such as: the third harmonic signal of the B12 transmitting frequency band (699-716 MHz) is in the frequency band of the B4 receiving frequency band (2110-2155 MHz), and if the downlink CA scene of B12 and B4 is supported, namely the two are operated simultaneously, interference is caused; therefore, if the B12 and B1 co-antenna is used, the high efficiency point of the third harmonic wave exists at the frequency band (2110-2155 MHz), and the operation of the B4 frequency band is interfered.

CA scenario intermodulation products of the main radio frequency and the main radio frequency disturb the main radio frequency signal, such as: second-order intermodulation products of a B42 transmitting frequency band (3400-3600 MHz) and a B41 transmitting frequency band (2496-2690 MHz) are in a B8 (925-960 MHz) frequency band, if a B42 and a B41 co-transmitting antenna in a radio frequency circuit generate frequency interfering with a B8 frequency band and support an uplink CA antenna; if the low-frequency B5 (869-894 MHz) is supported, an efficiency point is generated on B8, and at the moment, the three CAs of B42, B41 and B8 interfere the operation of B8 receiving due to the existence of the double uplink CAs of B42 and B41, so that sensitive DESECNCE is caused.

In the embodiment of the invention, when the B4 frequency band works, high efficiency is allowed at a frequency of GPS frequency 1575.42MHz to ensure normal work of B4 (wherein, the frequency bands of B4 and GPS do not interfere concurrently); when the B14 frequency band and the B13 frequency band work simultaneously, the efficiency of the GPS frequency point is low, the interference of the second harmonic signals of B14 and B13 to the GPS signals can be reduced, and the problem of signal interference in a frequency band concurrent mode is effectively solved; embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Example one

Referring to fig. 2, which illustrates an antenna adjustment method provided in an embodiment of the present invention, and the method is applied to a mobile terminal including at least a first antenna and a second antenna, and the method may include:

s201: acquiring network parameters of the mobile terminal in a communication process in real time; the network parameters at least comprise the working frequency band of the first antenna and the working frequency band of the second antenna;

s202: determining a working scene of the mobile terminal according to the network parameters;

s203: if the determined working scene is that the mobile terminal works in a frequency band concurrent mode, reducing the antenna efficiency of the first antenna at a harmonic interference frequency point; the harmonic interference frequency point is obtained according to the interference of the first antenna to the second antenna, and a frequency band concurrent mode is arranged between the working frequency band of the first antenna and the working frequency band of the second antenna.

For the technical solution shown in fig. 2, the method is applied to a mobile terminal at least including a first antenna and a second antenna, and obtains network parameters of the mobile terminal in a communication process in real time; the network parameters at least comprise the working frequency band of the first antenna and the working frequency band of the second antenna; determining a working scene of the mobile terminal according to the network parameters; if the determined working scene is that the mobile terminal works in a frequency band concurrent mode, reducing the antenna efficiency of the first antenna at a harmonic interference frequency point; the harmonic interference frequency point is obtained according to the interference of the first antenna to the second antenna, and a frequency band concurrent mode is arranged between the working frequency band of the first antenna and the working frequency band of the second antenna.

It should be noted that a frequency band concurrent mode is provided between the working frequency band of the first antenna and the working frequency band of the second antenna, and specifically includes that the mobile terminal simultaneously works in the working frequency band of the first antenna and the working frequency band of the second antenna, and the harmonic frequency corresponding to the working frequency band of the first antenna is close to the frequency corresponding to the working frequency band of the second antenna, and this close frequency point is called a harmonic interference frequency point; at this moment, according to the signal interference generated by the working frequency band of the first antenna to the working frequency band of the second antenna, the mobile terminal needs to reduce the antenna efficiency of the first antenna at the harmonic interference frequency point, so that the problem of signal interference brought by a frequency band concurrent mode is effectively solved, and meanwhile, the antenna performance is favorably improved, such as the accuracy of GPS positioning is improved, and the WIFI rate is improved.

For the technical solution shown in fig. 2, in a possible implementation manner, before the obtaining the network parameters of the mobile terminal in the communication process in real time, the method further includes:

acquiring control parameters corresponding to the first antenna under different antenna efficiencies through a debugging process of the first antenna;

and aiming at the first antenna, establishing a corresponding relation between the control parameter and the antenna efficiency.

It should be noted that the mobile terminal may perform control parameter debugging on the first antenna in advance, and obtain the control parameters corresponding to the first antenna under different antenna efficiencies according to the debugging result, so as to establish a corresponding relationship between the control parameters for the first antenna and the antenna efficiencies. It should be further noted that, for convenience of distinction, for the first antenna, different antenna states may also be set for different antenna efficiencies, for example, the first antenna of the mobile terminal may be preset with two states: the antenna efficiency corresponding to the first state is higher than that corresponding to the second state; then, the mobile terminal debugs the first antenna to obtain a control parameter corresponding to the first antenna in the first state corresponding to the antenna efficiency and a control parameter required by the first antenna in the second state corresponding to the antenna efficiency, so that the corresponding relationship between the control parameter and the states can be obtained. In the embodiment of the present invention, the debugging of the control parameter may be implemented by using a debugging method such as a variable capacitor, a variable inductor, an antenna tunnel, and an impedance matching circuit, which is not specifically limited in the embodiment of the present invention.

It is understood that the operating frequency band of the first antenna includes at least a first frequency band and a second frequency band, and the operating frequency band of the second antenna includes at least a third frequency band. Generally, a mobile terminal has multiple working scenes, and different working scenes have different requirements on antenna efficiency; in order to improve the performance of the antenna and different working scenes, the first antenna can be provided with different control parameters, so that the first antenna can adjust the antenna efficiency according to the working scenes; therefore, in the foregoing implementation manner, specifically, before the determining the working scenario of the mobile terminal according to the network parameter, the method further includes:

presetting at least two working scenes of the mobile terminal, wherein a first working scene of the at least two working scenes comprises that the mobile terminal works in the first frequency band and the third frequency band simultaneously, and a second working scene of the at least two working scenes comprises that the mobile terminal works in the second frequency band; the first antenna is shared by the first frequency band and the second frequency band in a time sharing mode, the second antenna is used by the third frequency band independently, the difference value between the harmonic frequency of the first frequency band and the frequency of the third frequency band is in a first preset frequency range, and the difference value between the frequency of the second frequency band and the frequency of the third frequency band is in a second preset frequency range;

respectively configuring corresponding control parameters aiming at the at least two working scenes based on the acquired control parameters;

and establishing the corresponding relation between the at least two working scenes and the control parameters and the antenna efficiency based on the corresponding relation between the control parameters and the antenna efficiency.

It should be noted that, a plurality of working scenarios are preset in the mobile terminal, and the working scenarios are mainly related to communication parameters (i.e. working frequency bands used for communication between the mobile terminal and the network side); in addition, the frequency band concurrency mode means that the first frequency band and the third frequency band work simultaneously, and the difference value between the harmonic frequency of the first frequency band or the intermodulation frequency of the first frequency band and other frequency bands and the frequency of the third frequency band is in a first preset frequency range; the first preset frequency range and the second preset frequency range are judgment values for measuring that two frequencies are close or close, and the first preset frequency range and the second preset frequency range may be the same or different, and the embodiment of the present invention is not limited specifically. For example, it is assumed that the mobile terminal can implement transceiving of radio frequency signals corresponding to the first frequency band, the second frequency band and the third frequency band through the first antenna and the second antenna; the first frequency band and the second frequency band share the first antenna in a time sharing manner, the third frequency band independently uses the second antenna, the first frequency band and the third frequency band have a frequency band concurrent mode, the difference between the harmonic frequency of the first frequency band and the frequency of the third frequency band is in a first preset frequency range (for example, the difference is less than 10MHz), and the difference between the frequency of the second frequency band and the frequency of the third frequency band is in a second preset frequency range (for example, the difference is also less than 10 MHz); in this way, the mobile terminal may set at least two working scenarios, such as a first working scenario and a second working scenario; the first working scene comprises that the mobile terminal works in a first frequency band and a third frequency band simultaneously, and the second working scene comprises that the mobile terminal works in a second frequency band; then respectively configuring corresponding control parameters aiming at the two working scenes, and obtaining the corresponding relation between the working scenes and the control parameters and the antenna efficiency based on the established corresponding relation between the control parameters and the antenna efficiency; for the first antenna, different control parameters can be called according to different working scenes, so that the first antenna can adjust the antenna efficiency according to the working scenes, the problem of signal interference brought under a frequency band concurrent mode is effectively solved, and the antenna performance is improved.

Here, the harmonic frequency or the mixing intermodulation frequency of the first frequency band is substantially similar to the frequency of the second frequency band or the third frequency band, and generally, the frequency point is a harmonic interference frequency point of the first frequency band; in order to solve the problem of signal interference in the frequency band concurrent mode, the embodiment of the invention increases the isolation of the antenna at the harmonic interference frequency point by reducing the antenna efficiency of the first antenna at the harmonic interference frequency point, thereby solving the problem of the concurrent interference when the first frequency band and the third frequency band are in the frequency band concurrent mode.

It should be further noted that, when the mobile terminal is in a communication process, the network parameters may be obtained in real time, where the network parameters at least include a working frequency band of the first antenna and a working frequency band of the second antenna; the working scene is related to the frequency band information, so that the working scene of the mobile terminal, such as the first working scene or the second working scene, and even other working scenes can be determined.

It can be understood that after the working scene of the mobile terminal is determined, the antenna efficiency of the first antenna at the harmonic interference frequency point can be adjusted based on the working scene and the interference degree of the working frequency band of the first antenna to the working frequency band of the second antenna; wherein the content of the first and second substances,

in the foregoing specific implementation manner, preferably, if the determined working scenario is that the mobile terminal works in a frequency band concurrent mode, the reducing the antenna efficiency of the first antenna at a harmonic interference frequency point specifically includes:

when the determined working scene is the first working scene, controlling the first antenna to work at the harmonic interference frequency point according to the corresponding relation between the at least two working scenes and the control parameters and the antenna efficiency according to the control parameters corresponding to the first working scene; and the control parameter corresponding to the first working scene is used for representing that the antenna efficiency of the first antenna is low.

In the foregoing specific implementation manner, preferably, if the determined working scenario is that the mobile terminal works in the second frequency band, the antenna efficiency of the first antenna at the harmonic interference frequency point needs to be improved; thus, the method further comprises:

when the determined working scene is the second working scene, controlling the first antenna to work at the harmonic interference frequency point according to the corresponding relation between the at least two working scenes and the control parameters and the antenna efficiency according to the control parameters corresponding to the second working scene; and the control parameter corresponding to the second working scene is used for representing that the antenna efficiency of the first antenna is high.

It should be noted that, after the working scene of the mobile terminal is determined, if the determined working scene is the first working scene, that is, the mobile terminal simultaneously works in the first frequency band and the third frequency band, because the first frequency band and the third frequency band are in a frequency band concurrent mode, and the interference degree of the first frequency band to the third frequency band is large, at this time, the antenna efficiency of the first antenna at the harmonic interference frequency point needs to be relatively low; that is to say, according to the correspondence between the at least two working scenes and the control parameters and the antenna efficiency, the first antenna is controlled to work at the harmonic interference frequency point according to the control parameters corresponding to the first working scene; if the determined working scene is a second working scene, namely the mobile terminal simultaneously works in the second frequency band, because the interference degree of the second frequency band to the third frequency band is small, the antenna efficiency of the first antenna at the harmonic interference frequency point needs to be higher in order to ensure the normal work of the second frequency band; that is to say, according to the correspondence between the at least two working scenes and the control parameters and the antenna efficiency, the first antenna is controlled to work at the harmonic interference frequency point according to the control parameters corresponding to the second working scene; therefore, the problem of signal interference brought by a frequency band concurrent mode can be effectively solved, and meanwhile, the performance of the antenna is improved.

It should be noted that, after the antenna efficiency of the first antenna is adjusted, the mobile terminal may continue to perform communication with the network side based on the adjusted antenna efficiency, and then determine the working scenario of the mobile terminal according to the network parameter obtained in real time, so as to adjust the antenna efficiency of the first antenna again according to the working scenario of the mobile terminal.

For the technical solution shown in fig. 2, in a possible implementation manner, the method further includes:

and if the determined working scene is that the mobile terminal works in the working frequency band of the first antenna and the working frequency band of the second antenna in a time-sharing manner, continuously maintaining the antenna efficiency of the first antenna.

It should be noted that, when the determined working scenario is that the mobile terminal does not work in the working frequency band of the first antenna and the working frequency band of the second antenna at the same time, there is no frequency band concurrent interference problem, at this time, the antenna efficiency of the first antenna may not be adjusted, and the antenna efficiency of the first antenna is continuously maintained, and the mobile terminal may continue to perform communication with the network side based on the maintained antenna efficiency, and determine the working scenario of the mobile terminal according to the network parameter obtained in real time again, so as to facilitate adjustment of the antenna efficiency of the first antenna according to the working scenario of the mobile terminal again.

It should be further noted that, when the determined operating scenario is that the mobile terminal simultaneously operates in the operating frequency bands of the first antenna and the second antenna, but the two operating frequency bands do not have the frequency band concurrent interference problem, at this time, the antenna efficiency of the first antenna may not be adjusted, and the antenna efficiency of the first antenna is continuously maintained.

The embodiment provides an antenna state adjusting method, which is applied to a mobile terminal at least comprising a first antenna and a second antenna and used for acquiring network parameters of the mobile terminal in a communication process in real time; the network parameters at least comprise the working frequency band of the first antenna and the working frequency band of the second antenna; determining a working scene of the mobile terminal according to the network parameters; if the determined working scene is that the mobile terminal works in a frequency band concurrent mode, reducing the antenna efficiency of the first antenna at a harmonic interference frequency point; the harmonic interference frequency point is obtained according to the interference of the first antenna to the second antenna, and a frequency band concurrent mode is arranged between the working frequency band of the first antenna and the working frequency band of the second antenna; therefore, the problem of signal interference brought under a frequency band concurrent mode can be effectively solved, and meanwhile, the antenna performance is favorably improved, such as the accuracy of GPS positioning and the WIFI rate are improved.

Referring to fig. 3, a schematic structural diagram of a conventional radio frequency circuit of a mobile terminal according to an embodiment of the present invention is shown; as shown in fig. 3, the conventional rf circuit 300 includes a power amplifier 301, an rf transceiver 302, a duplexer 303, a switch 304, a test socket 305, and an antenna 306; based on the conventional radio frequency circuit 300, the radio frequency signal transmission and reception of the mobile terminal can be realized; in the use process of the mobile terminal, when radio frequency signals of a plurality of frequency bands are concurrent, in order to solve the problem that the sensitivity of the antenna is reduced because harmonic signals cannot be inhibited under the condition that the radio frequency signals are concurrent because the plurality of frequency bands share the antenna, in the embodiment of the invention, an adjustable unit can be added in a radio frequency circuit; referring to fig. 4, which shows a schematic structural diagram of an improved rf circuit of a mobile terminal according to an embodiment of the present invention, on the basis of the conventional rf circuit 300 shown in fig. 3, the improved rf circuit 400 further includes an antenna efficiency adjustable unit 401 and a baseband processing unit 402, where both the operating scenario parameter and the control parameter of the antenna efficiency adjustable unit 401 are stored in the baseband processing unit 402, and then the baseband processing unit 402 controls the antenna efficiency adjustable unit 401.

For the antenna efficiency adjustable unit 401, refer to fig. 5, which shows a schematic structural diagram of an antenna system according to an embodiment of the present invention; as shown in fig. 5, the antenna system mainly includes three parts, namely, an antenna matching circuit, an antenna radiating element (i.e., an antenna trace) and a corresponding feed point; in fact, the antenna efficiency is formed by jointly debugging the three parts, and the change of each part causes the change of the antenna efficiency. In the embodiment of the invention, the debugging of the antenna efficiency can be carried out according to the three parts; different debugging methods can be adopted for different parts, and the debugging methods corresponding to the three parts are explained in detail below; here, the debugging method is not particularly limited in the embodiment of the present invention.

Firstly, for the antenna matching circuit part, generally, an adjustable capacitance inductor can be selected; referring to fig. 6, a schematic structural diagram of an adjustable capacitance inductor according to an embodiment of the present invention is shown; the adjustable capacitance inductor consists of a voltage-controlled variable capacitance inductor part and a voltage-controlled circuit; in the actual use process, a group of voltage and capacitance inductance value curve graphs are required to be obtained in advance according to the actual characteristics of the voltage-controlled variable capacitance inductance part and parameters provided by a manufacturer; then, pre-debugging the antenna efficiency and the antenna matching unit is carried out, the relation between the capacitance, the inductance and the debugging frequency point efficiency is determined, and then the relation is converted into a voltage relation, for example, when the high efficiency of the harmonic interference frequency point is assumed, the adjustable capacitance inductance value is C1, when the low efficiency of the harmonic interference frequency point is assumed, the adjustable capacitance inductance value is C2, and the voltage values V1 and V2 corresponding to the values of C1 and C2 at the moment are stored in a storage unit of the mobile terminal; in subsequent practical applications, if the baseband processing unit 402 determines that high efficiency needs to be output, the baseband processing unit 402 controls the voltage-controlled circuit to output the voltage V1, that is, the matching of the antenna at this time is the point C1, and a state of high antenna efficiency is correspondingly obtained; and on the contrary, the output voltage V2, namely the matching of the antenna at the moment is C2 point, correspondingly obtains the state of low antenna efficiency, thereby inhibiting the concurrent interference.

Secondly, for the radiation unit and the ground feed point of the antenna, an antenna tunnel is generally added to the corresponding ground feed point of the antenna for debugging; generally speaking, the radiation arms of the antenna radiation units are different for different frequency bands; referring to fig. 7, it shows a schematic structural diagram of an antenna radiation arm and a feed point distribution provided in an embodiment of the present invention; as shown in fig. 7, the a-band radiating element is located at the left part of fig. 7, and the C-band radiating element is located at the right part of fig. 7, so that different antenna tunnels can be added to different radiating arms or ground feed points to adjust the ground feed points; as can be seen from fig. 5, the antenna switches generally have different values, and several groups of states can be pre-debugged according to the relationship between the antenna efficiency and the different values corresponding to the switches in actual use, for example, assuming that the corresponding switch state is S1 when the antenna efficiency of the harmonic interference frequency point is high, and the corresponding switch state is S2 when the antenna efficiency of the harmonic interference frequency point is low, the switch control logics G1 and G2 corresponding to the values S1 and S2 at this time are stored in the storage unit of the mobile terminal; in subsequent practical applications, if the baseband processing unit 402 determines that high antenna efficiency needs to be output, the baseband processing unit 402 controls the switch control circuit to output the switch control logic G1, that is, the switch state of the antenna is at S1, and a state with high antenna efficiency is obtained correspondingly; otherwise, the output switch control logic G1, namely the switch state of the antenna is S2 point, correspondingly obtains the state of low antenna efficiency, thereby restraining the concurrent interference.

It should be noted that, the state of the actual antenna may be adjusted by devices including, but not limited to, a variable inductor, a variable capacitor, an antenna tunnel, and the like, so as to increase the range of the type selection of the radio frequency device.

In the embodiment of the present invention, in combination with the improved rf circuit 400 shown in fig. 4, the antenna efficiency adjustable unit 401 is controlled by the baseband processing unit 402 according to the obtained actual network parameters (i.e., communication parameters), so that respective control of different frequency bands and different concurrent scenarios in the rf circuit is realized, which specifically includes control of the following scenarios:

(1) when the antenna works in a concurrent interference frequency band and a concurrent scene of harmonic mixing interference exists, the antenna efficiency of a harmonic interference frequency point in the interference frequency band needs to be suppressed; therefore, the antenna isolation degree in a concurrent scene is increased, and the problem of concurrent interference of radio frequency signals is solved;

(2) when the non-concurrent interference frequency band or the harmonic mixing interference concurrent scene does not exist, the antenna efficiency does not need to be adjusted, and the normal work of the antenna is ensured;

(3) when the antenna works in a common antenna adjacent frequency band adjacent to harmonic interference, the antenna state with higher antenna efficiency must be used at the harmonic interference frequency point, and the transceiving performance of the antenna is ensured.

In the embodiment of the present invention, in combination with the improved radio frequency circuit 400 shown in fig. 4, according to the provided antenna efficiency adjustable unit 401 for the harmonic interference frequency point, the antenna efficiency can be adjusted by the antenna efficiency adjustable unit 401 based on the working scene, so that the problem of interference of a harmonic signal in a low frequency band to a corresponding high frequency band signal during radio frequency concurrency is solved, the model selection range of a radio frequency device is increased, the device cost is reduced, the scheme layout is facilitated, and meanwhile, the working performance and the state of the antenna are not affected.

EXAMPLE III

It is assumed that embodiments of the present invention mainly relate to four frequency bands: frequency band A, frequency band B, frequency band C and frequency band X; the frequency band a, the frequency band B, the frequency band C and the frequency band X are specifically described as follows:

(1) the frequency band A and the frequency band C share a first antenna, and the frequency band B is a single second antenna;

(2) the frequency band A and the frequency band B have concurrent use scenes;

(3) nonlinear high-order harmonics (second harmonic, third harmonic, etc.) of the frequency band a or intermodulation frequencies of other frequency bands X, which are the same as or similar to the frequencies of the frequency band B (frequency difference is less than 10MHz), may interfere with the operation of the frequency band B;

(4) band a and band C share a first antenna and are not supported simultaneously. The frequency of the frequency band C is close to the frequency of the frequency band B (frequency difference is less than 10MHz), and the frequency band C generally does not interfere with the operation of the frequency band B, so that the first antenna of the frequency bands a and C has higher antenna efficiency on the frequency band B.

The harmonic frequency or the mixing intermodulation frequency of the frequency band a is substantially similar to the frequency of the frequency bands B and C, and this frequency point is defined as the harmonic interference frequency point (interference).

In the embodiment of the present invention, the following two scene conditions are mainly used:

(1) because the first antenna is shared by multiple frequency bands (such as the frequency band A and the frequency band C), the harmonic frequency or the mixing intermodulation frequency of the frequency band A is close to the frequency of the resonance frequency band (such as the frequency band C), so that the efficiency of the first antenna at the frequency point is higher;

(2) the presence of harmonic frequencies or mixed intermodulation frequencies (such as band a of the first antenna) and in the band concurrency mode may interfere with other antenna bands (such as band B of the second antenna), requiring a reduction in the efficiency of the first antenna at that frequency point.

It should be noted that the common first antenna of the frequency band a and the frequency band C has at least the following two states, and can be distinguished by the antenna efficiency of the frequency band B, that is, the harmonic interference frequency of the frequency band a:

(1) the antenna efficiency of the common first antenna of the frequency band A and the frequency band C at the frequency band B (harmonic interference frequency band of the frequency band A) is high, and the common first antenna is defined as a first state;

(2) the antenna efficiency of the common first antenna of the frequency band a and the frequency band C at the frequency point of the frequency band B (the harmonic interference frequency point of the frequency band a) is low, and is defined as the second state.

Based on the same inventive concept of the foregoing embodiment, referring to fig. 8, which shows a detailed flowchart of an antenna adjusting method provided in an embodiment of the present invention, in combination with the structure example of the mobile terminal improved radio frequency circuit shown in fig. 4, the detailed flowchart includes:

s801: acquiring control parameters corresponding to the first antenna under different antenna efficiencies through a debugging process of the first antenna; the acquired control parameters comprise control parameters corresponding to a first state and control parameters corresponding to a second state;

s802: establishing a correspondence between the control parameter and the state for the first antenna;

s803: acquiring network parameters of the mobile terminal in a communication process in real time;

s804: judging whether to work in a frequency band C or not according to the network parameters;

s805: if the antenna works in the frequency band C, adjusting the current state of the first antenna to be a first state by calling a control parameter corresponding to the first state;

s806: if the frequency band does not work in the frequency band C, judging whether the frequency band A and the frequency band B work;

s807: if the frequency band A and the frequency band B work, judging whether the frequency band A and the frequency band B work in a frequency band concurrent mode or not;

s808: if the antenna does not work in the frequency band A and the frequency band B, the state of the first antenna is not adjusted, and the current state of the first antenna is still maintained;

s809: if the antenna works in the frequency band concurrent mode of the frequency band A and the frequency band B, adjusting the current state of the first antenna to be the second state by calling a control parameter corresponding to the second state;

s810: if the mobile terminal does not work in the frequency band concurrent mode of the frequency band A and the frequency band B, the state of the first antenna is not adjusted, and the current state of the first antenna is still maintained.

Note that, after step 807, step S809 and step S810 are executed; it should be noted that, after steps S805, S808, S809, and S810, step S803 may be returned to, and the network parameters are continuously obtained in real time according to the communication process of the mobile terminal; and judging whether the state of the first antenna needs to be adjusted or not according to the acquired network parameters.

For example, assume that the frequency band a is the B13 or B14 frequency band of the main antenna of the mobile terminal, the frequency band B is the GPS frequency band of the GPS antenna of the mobile terminal, and the frequency band C is the B4 frequency band of the main antenna of the mobile terminal; namely, several frequency bands of B4, B13 and B14 share a main antenna but do not work simultaneously, a GPS frequency band is a single antenna, and a simultaneous working scene exists among B4, B13, B14 and GPS; firstly, judging whether the network works in a B4 frequency band or not according to the acquired network parameters; when the judgment result is that the antenna works in the B4 frequency band, the B4 frequency is close to the GPS frequency, so that the antenna efficiency of the B4 is high, the antenna efficiency of the main antenna at the GPS frequency point can be improved, the main antenna works in the first state, and the normal work of the B4 is ensured; when the judgment result is that the mobile terminal does not work in the B4 frequency band, judging whether the mobile terminal works in the B13 (or B14) and the GPS frequency band again; when the judgment result is that the mobile terminal works in the B13 (or B14) and GPS frequency bands, because the second harmonic frequency of B13 (or B14) is very close to the GPS frequency point, interference is generated on the GPS, and whether the mobile terminal works in the frequency band concurrency mode of B13 (or B14) and the GPS frequency band needs to be judged; when the judgment result is that the antenna works in a frequency band concurrent mode of a B13 (or B14) frequency band and a GPS frequency band, namely the B13 (or B14) frequency band and the GPS frequency band work simultaneously, because the second harmonic frequency of the B13 (or B14) is very close to the GPS frequency point, interference is generated on the GPS, the antenna efficiency of the main antenna at the GPS frequency point needs to be reduced, the main antenna works in a second state, the antenna efficiency of the corresponding harmonic frequency point of the interfered frequency band is reduced, and the antenna isolation in the frequency band concurrent mode is increased; when the judgment result is that the antenna does not work in the B13 (or B14) and GPS frequency bands or does not work in the frequency band concurrent mode, the state of the first antenna is not adjusted because the frequency band concurrent interference does not exist, and the current state of the first antenna is still maintained.

It should be further noted that the first state and the second state are controlled by the antenna efficiency adjusting unit; the antenna efficiency adjustable unit carries out high-low debugging on the antenna efficiency aiming at the harmonic interference frequency point (namely, frequency band B frequency point) of the frequency point A; when the frequency band B and the frequency band A work simultaneously and are in a frequency band concurrent mode, the first antennas of the frequency bands A and C are in a second state, so that the antenna efficiency aiming at harmonic interference frequency points can be reduced, the isolation of the antennas at the harmonic interference frequency points is increased, and the problem of concurrent interference caused by the frequency band A and the frequency band B in the frequency band concurrent mode is effectively solved; when the frequency band C works, the first antennas of the frequency band A and the frequency band C are in a first state, so that the antenna efficiency at a harmonic interference frequency point is improved, and the normal work of the frequency band C can be effectively ensured; for other scene combinations, the antenna state can be adjusted to be in the corresponding antenna optimal state.

Through the embodiment, the specific implementation of the embodiment is elaborated in detail, and it can be seen that through the technical scheme of the embodiment, the problem of signal interference brought under a frequency band concurrent mode can be effectively solved, and meanwhile, the antenna performance is facilitated to be improved, such as the accuracy of GPS positioning and the WIFI rate are improved.
