Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the method for processing antenna frequency offset according to the embodiment of the present invention includes:
in this embodiment, optionally, the antenna module includes a dielectric substrate, and the dielectric substrate may be in a voltage-controlled form, that is, the relative permittivity of the dielectric substrate may change with a change of the dc bias voltage, and when the voltage on two sides of the dielectric substrate increases, the relative permittivity of the dielectric substrate increases, and conversely, when the voltage on two sides of the dielectric substrate decreases, the relative permittivity of the dielectric substrate decreases. The dielectric substrate may be controlled in other forms, such as current control and pressure control, that is, the relative permittivity of the dielectric substrate may be changed according to the change of the bias current or the pressure applied to the dielectric substrate.
In this embodiment, as shown in fig. 2, taking the antenna module including 4 patch antennas 21 and 4 dipole antennas 22 and a dielectric substrate 23 as an example, fig. 2 is a top view of the antenna module, where the patch antennas 21 generate broadside radiation patterns, the dipole antennas 22 generate end-fire radiation patterns, the patch antennas 21 may be square or rectangular and are attached to the surface of the dielectric substrate 23 with adjustable relative dielectric constant, and circles in fig. 2 represent vertically polarized feeding points and horizontally polarized feeding points, and these feeding points are connected to the inside of the rf chip on the bottom surface through a through hole passing through the dielectric layer.
In the embodiment, the working frequency range of the antenna module is divided into a plurality of frequency bands, the numerical values of the EIRP of the antenna module in different working frequency bands are respectively obtained, and when the different working frequency bands comprise a plurality of frequency points, the numerical values of the EIRP of each frequency point are required to be obtained.
the value of the EIRP is used to indicate the transmit power in the direction of maximum antenna gain obtainable by the transmitter compared to an omni-directional antenna. By actually measuring the value of the EIRP, it can be determined whether the antenna module has frequency shift under the influence of the surrounding environment, so as to determine whether the relative dielectric constant of the dielectric substrate needs to be adjusted.
And 103, adjusting the relative dielectric constant of the dielectric substrate when the antenna module generates frequency offset.
The relative dielectric constant is a physical parameter for representing the dielectric property or polarization property of a dielectric material, and the value of the physical parameter is equal to the capacitance ratio of a capacitor with the same size which is made by taking the material of the dielectric substrate as a medium and taking vacuum as a medium, and the value is also used for representing the electricity storage capacity of the material. The relative dielectric constant of the dielectric substrate is related to parameters such as voltage, current and pressure acting on the dielectric substrate, which are introduced into the dielectric substrate. When the antenna module is detected to generate frequency deviation, the resonant frequency of the antenna module can return to a normal value by adjusting the relative dielectric constant, so that the deviation condition of the resonant frequency of the antenna module in the actual environment is adjusted.
In the embodiment, whether the antenna module generates the resonant frequency deviation under the influence of the surrounding environment is determined by obtaining the numerical values of the EIRPs of the antenna module at different working frequency bands, when the antenna module generates the frequency deviation, under the condition of not changing the structural size of the antenna, the adjustment of the frequency deviation of the antenna module is realized by adjusting the relative dielectric constant of the dielectric substrate of the antenna module, the problem that the antenna resonant frequency deviation influences the performance of the antenna is solved, the operation is simple and practical, and the practical engineering practical significance is achieved.
Specifically, the step 101 may include:
and acquiring a result of the air interface test of the antenna module, wherein the result of the air interface test comprises numerical values of EIRPs of the antenna module in different working frequency bands.
When the numerical values of the EIRP of the antenna module in different working frequency bands are obtained, the numerical values of the EIRP can be obtained by performing an air interface test on the antenna module. Optionally, as shown in fig. 3, two ends of a dielectric substrate of the antenna module are connected to a voltage-adjustable power supply, and before performing an air interface test, a voltage value of the power supply is set to be an initial voltage, where the initial voltage is set according to a material of the dielectric substrate; after an initial voltage is given, the dielectric substrate obtains an initial relative dielectric constant; and then carrying out an air interface test on the antenna module, wherein the output result of the air interface test is the numerical value of the EIRP of the antenna module in different working frequency bands.
The air interface test is a test of the radiation performance of the terminal equipment. The radiation performance of the terminal equipment is tested in two forms: active testing and passive testing. The air interface test is an active test, which is to test the transmitting power and receiving sensitivity of the terminal equipment in each direction of a three-dimensional space in a specific microwave darkroom, and can directly reflect the radiation performance of the terminal equipment.
Optionally, as shown in fig. 4, the step 102 includes:
after the numerical values of the EIRP of the antenna module in different working frequency bands are obtained, whether the resonant frequency of the antenna module in the actual working environment deviates or not is judged by judging the numerical values of the EIRP. Specifically, the shift condition of the resonant frequency of the antenna module in the actual working environment can be judged through the distribution condition of the peak values of the EIRP of the antenna module in the main radiation direction (maximum transmission direction) of different frequency bands, and the maximum value of the EIRP values of each frequency point of different working frequency bands is the peak value of the EIRP.
the peak distribution in the values of the EIRP in the first frequency band may be considered that the resonant frequency of the antenna module is not shifted. The first frequency band may be a frequency band preset in the whole operating frequency range of the antenna module, and may be determined according to the actual operating condition of the antenna module, so that it should be ensured that the radiation performance of the antenna module is not affected or less affected by the surrounding environment in the frequency band, and the radiation performance of the antenna module in the frequency band is optimal.
The peak value of the EIRP value is distributed in the second frequency band or the third frequency band, and it is considered that the resonant frequency of the antenna module is shifted under the influence of the surrounding environment. The frequency of the second frequency band is less than the frequency of the first frequency band, that is, the second frequency band is a low frequency band; the frequency of the first frequency band is less than the frequency of the third frequency band, namely the third frequency band is a high-frequency band; the first frequency band is a center frequency band.
In this embodiment, by determining the distribution of the peak in the EIRP value, it can be determined whether the antenna module is frequency-shifted under the influence of the surrounding environment, so that the terminal device can adjust the antenna module in time when the antenna module is frequency-shifted, and the radiation performance of the antenna module is effectively ensured.
Specifically, the step 103 may include:
and if the peak value is distributed in the second frequency band, and the maximum value of the EIRP values distributed in the first frequency band is larger than the maximum value of the EIRP values distributed in the third frequency band, reducing the relative dielectric constant of the dielectric substrate.
And if the peak value is distributed in the third frequency band, and the maximum value of the EIRP values distributed in the first frequency band is larger than the maximum value of the EIRP values distributed in the second frequency band, increasing the relative dielectric constant of the dielectric substrate.
Taking the example that the working frequency of the antenna module is divided into three frequency bands, namely a low frequency band, a central frequency band and a high frequency band. Because the frequency of the second frequency band is less than the frequency of the first frequency band, the frequency of the first frequency band is less than the frequency of the third frequency band, namely the second frequency band is the low frequency band, the first frequency band is a center frequency band, and the third frequency band is the high frequency band. When the peak value is distributed in the second frequency band or the third frequency band, it is considered that the resonant frequency of the antenna module is shifted under the influence of the surrounding environment, and at this time, the adjustment of the frequency shift can be realized by adjusting the relative dielectric constant of the dielectric substrate.
If the peak value of the EIRP values is distributed in the low frequency band and the maximum value of the EIRP values distributed in the first frequency band is greater than the maximum value of the EIRP peak value distributed in the third frequency band, the relative dielectric constant of the dielectric substrate needs to be reduced by adjusting parameters such as pressure acting on the dielectric substrate, so as to improve the resonant frequency of the antenna module and distribute the peak value in the central frequency band; if the peak value in the EIRP values is distributed in the high frequency band, the relative dielectric constant of the dielectric substrate needs to be increased by adjusting parameters such as the pressure acting on the dielectric substrate, and the like, so as to reduce the resonant frequency of the antenna module and distribute the peak value in the central frequency band. The peak value in the EIRP values is distributed in the central frequency band, and the antenna module at the moment is considered to have no frequency offset.
Optionally, the dielectric substrate is connected with a power supply; the step 103 comprises:
and adjusting the voltage of the power supply, the current of the power supply or the pressure acting on the dielectric substrate to adjust the relative dielectric constant of the dielectric substrate.
In this embodiment, when it is determined that the antenna module has a frequency offset, the relative dielectric constant may be adjusted by adjusting a voltage or a current of a power supply or a pressure applied to the dielectric substrate. Taking the adjustment voltage as an example, the relative dielectric constant of the dielectric substrate is related to the dc bias voltage of the dielectric substrate, when the voltage on both sides of the dielectric substrate increases, the relative dielectric constant of the dielectric substrate increases, and when the voltage on both sides of the dielectric substrate decreases, the relative dielectric constant of the dielectric substrate decreases.
The relative dielectric constant of the dielectric substrate is adjustable, the relative dielectric constant of the dielectric substrate is changed by controlling the external input voltage of the dielectric substrate, the relative dielectric constant of the dielectric substrate material is correspondingly changed along with different environments, the resonant frequency of the antenna module is further adjusted, and therefore the influence of the actual environment on the antenna module is eliminated. Utilize this kind of dielectric substrate preparation antenna module has remain the design and the processing technology of current antenna module as far as, and does not additionally increase antenna module's the design and the processing degree of difficulty, can eliminate the influence of surrounding environment to antenna module, and it still is suitable for on the item of lid behind the non-metallic material such as glass, pottery, plastic, can promote the feel and the outward appearance of product better, promotes the competitiveness of product.
The following describes a process of adjusting the relative dielectric constant by adjusting voltages at two sides of a dielectric substrate when determining that the antenna module generates a frequency offset according to a specific embodiment.
As shown in fig. 5, assuming that the operating frequency of the antenna module is n257(26.5-29.5GHz), n257 is divided into three frequency bands: when the antenna module is placed in an actual complete machine environment, the EIRP of a peak value displayed by an air interface test result is distributed in the low frequency band (26.5-27.9GHz), and the maximum value of the EIRP values of a plurality of frequency points distributed in the central frequency band is larger than the maximum value of the EIRP values of a plurality of frequency points distributed in the high frequency band, the voltage of the power supply is reduced to reduce the relative dielectric constant of the dielectric substrate, so that the resonant frequency of the antenna module is increased until the EIRP of the peak value in the main emission direction is distributed in the central frequency band (27.9-28.1GHz), and the resonant frequency of the antenna module is considered not to be deviated in the actual environment; when the value of the peak EIRP of the air interface test result of the antenna module is distributed in the high-frequency band (28.1-29.5GHz), and the maximum value of the EIRP values of the multiple frequency points distributed in the central frequency band is greater than the maximum value of the EIRP values of the multiple frequency points distributed in the low-frequency band, the voltage of the power supply should be increased to increase the relative dielectric constant of the dielectric substrate, so that the resonant frequency of the antenna module is reduced until the peak EIRP in the main radiation direction is distributed in the central frequency band (27.9-28.1GHz), and it can be considered that the resonant frequency of the antenna module is not shifted in the actual environment.
Based on the embodiment, the frequency offset of the antenna module is adjusted by adjusting the dielectric constant of the dielectric substrate, the beams on the base station side and the terminal device side can be fixed at a certain fixed and static position, the relative dielectric constant values are changed by a preset step length, each relative dielectric constant value has a corresponding reported signal level, the magnitude of the signal level values is compared, the dielectric constant value corresponding to the maximum signal level value is selected to serve as the optimal parameter value of the current environment, and the frequency of the antenna module can be adjusted more intelligently. The antenna frequency offset processing method of the embodiment of the invention can also be applied to wireless communication design and application such as wireless inter-city networks, wireless wide area networks, wireless local area networks, wireless personal networks, multiple input multiple output, radio frequency identification, near field communication, wireless charging and the like.
It should be noted that the antenna module according to the embodiment of the present invention may be a millimeter wave antenna module, the antenna units of the millimeter wave antenna module are mainly patch antennas, yagi-uda antennas or dipole antennas, and these antenna units are all narrow band antennas, for example, the relative bandwidth of a conventional patch antenna is generally not more than 8%, and the millimeter wave frequency band usually requires a broadband dual-frequency or multi-frequency form, and in order to meet the requirements of a broadband, a dual-frequency, or even a multi-frequency, for the patch antenna, a slot is often required on a radiation sheet of the patch antenna or a laminated structure is adopted, but the thickness of the millimeter wave antenna module may be increased, which is not favorable for the miniaturization and the whole-machine integration of the millimeter wave antenna module. According to the embodiment of the invention, when the resonance frequency offset of the antenna module under the influence of the surrounding environment is determined, the frequency offset of the antenna module can be adjusted by adjusting the relative dielectric constant of the dielectric substrate of the antenna module, the structural size of the antenna module does not need to be changed, the operation is simple and practical, and the practical engineering practice significance is achieved.
In summary, in the embodiments of the present invention, it is determined whether the antenna module generates the resonant frequency shift under the influence of the surrounding environment by obtaining the values of the EIRPs of the antenna module in different working frequency bands, and when the antenna module generates the frequency shift, the adjustment of the frequency shift of the antenna module is implemented by adjusting the relative dielectric constant of the dielectric substrate of the antenna module without changing the structural size of the antenna, so as to solve the problem that the antenna resonant frequency shift affects the performance of the antenna.
