Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Fig. 1 is a first schematic structural diagram of an antenna module according to an exemplary embodiment. As shown in fig. 1, the antenna module is located on a conductive sheet, and the antenna module includes:
one or more antennas; wherein the content of the first and second substances,
a plurality of antenna radiators 102 of the plurality of antennas are constituted by different regions of the conductive sheet;
an antenna radiator 102 of one of the antennas is constituted by at least part of the conductive sheet.
In the embodiment of the present disclosure, the antenna module is applied to a terminal device, and the terminal device may be a mobile terminal or a wearable electronic device. The mobile terminal comprises a smart phone, a notebook or a tablet computer; this wearable electronic equipment includes the smart watch, and this disclosed embodiment does not put a limit to.
The antenna module can realize communication between two terminal devices. For example, communication between the smart phone and the smart phone is realized through the antenna module; or, the communication between the smart phone and the wearable electronic device is realized through the antenna module.
In some embodiments, the antenna module may include at least one of:
an ultra-wideband antenna; a wireless fidelity antenna; a Bluetooth antenna; a satellite antenna for receiving satellite signals; a millimeter wave antenna.
The ultra-wideband antenna can be used for receiving and transmitting wireless signals in a frequency band of 3.1GHz to 10.6 GHz; the wireless fidelity antenna can be used for receiving and transmitting wireless signals in a frequency band from 5.925GHz to 7.125 GHz; the Bluetooth antenna can be used for receiving and transmitting wireless signals in a frequency range of 2.4GHz to 2.483 GHz; the satellite antenna is used for receiving and transmitting wireless signals with the frequency of 1575.42MHz or 1228 MHz; the millimeter wave antenna can be used for receiving and transmitting wireless signals in the frequency band of 26.5GHz to 300 GHz.
As shown in fig. 1, a conductive sheet of an embodiment of the present disclosure is located on a substrate 101.
The substrate is used for bearing the antenna radiator. When the antenna module is applied to the terminal equipment, the substrate can be reused as a frame surrounding the terminal equipment and exposed outside in the terminal equipment, a middle frame arranged inside the terminal equipment and surrounded by the frame or a back shell of the terminal equipment; the substrate can be reused as a main board of the terminal device, and the embodiment of the disclosure is not limited.
Illustratively, the thickness of the substrate may be between 0.01 mm and 3 mm. The substrate may be made of epoxy fiber or Polyimide (PI) grade flame retardant FR 4.
In the embodiment of the disclosure, when the substrate is reused as a printed circuit board of a terminal device, the conductive sheet on the substrate may be a single copper-clad sheet on the printed circuit board.
Illustratively, the thickness of the copper metallization may be 0.009 millimeters, 0.018 millimeters, or 0.035 millimeters, without limitation by embodiments of the present disclosure.
The antenna module includes: one or more antennas; one antenna corresponds to each antenna radiator. The antenna radiator is used for receiving and transmitting wireless signals. When transmitting a wireless signal, the antenna radiator converts high-frequency current into high-frequency electromagnetic waves; when receiving wireless signals, the antenna radiator converts received high-frequency electromagnetic waves into high-frequency current.
For example, the plurality of antennas include two antennas, and two antenna radiators corresponding to the two antennas may be both antenna radiators of an ultra wideband antenna, and receive and transmit wireless signals of the same frequency band; and one antenna radiator of the ultra-wideband antenna and the other antenna radiator of the Bluetooth antenna can receive and transmit wireless signals of different frequency bands.
In the embodiments of the present disclosure, the plurality of antenna radiators of the plurality of antennas are formed by different regions of the conductive sheet, that is, the plurality of antenna radiators share one conductive sheet.
In the embodiment of the present disclosure, the plurality of antenna radiators may be areas where different sides of the same conductive sheet are located. For example, when the conductive sheet is triangular, three antenna radiators included in the plurality of antenna radiators may be regions where three sides of the conductive sheet are located; when the conductive sheet is rectangular, the four antenna radiators included in the plurality of antenna radiators may be regions where the four sides of the conductive sheet are located.
The plurality of antenna radiators can also be regions where included angles between adjacent sides in the same conductive sheet are located. For example, when the conductive sheet is rectangular, four antenna radiators included in the plurality of antenna radiators may be regions where four included angles of the conductive sheet are located; when the conductive sheet is pentagonal, the five antenna radiators included in the plurality of antenna radiators may be regions where the five included angles of the conductive sheet are located.
The plurality of antenna radiators may also be regions where different ends of the same conductive sheet are located. For example, when the conductive sheet is cross-shaped, the four antenna radiators included in the multiple antenna radiations may be regions where four symmetrical ends of the conductive sheet are located; when the conductive sheet is in a delta shape, three antenna radiators included in the plurality of antenna radiators may be regions where three ends of the conductive sheet are located.
It should be noted that two adjacent antenna radiators in the plurality of antenna radiators share a single conductive sheet. The area occupied by one antenna radiator on the conductive sheet is a first area; the area occupied by the other antenna radiator on the conductive sheet is a second area; the first area and the second area are two connected areas, or two sub-areas which are continuously distributed.
In the related art, as shown in fig. 2, 3, and 4, a single antenna radiator 202 having a size of 20mm × 16mm is provided on a substrate 201, and the maximum value of the standing wave ratio of the antenna radiator is 2.42.
As shown in fig. 5, the standing wave ratios of the antenna radiators are all within 2.25 by using the solution of the embodiment of the present disclosure. As shown in fig. 6, the radiation efficiency of the antenna radiator according to the embodiment of the present disclosure is close to 1, and the radiation efficiency can be greatly improved. It can be seen that the plurality of antenna radiators of the embodiments of the present disclosure share one conductive sheet, which can improve the overall performance of the antenna.
It can be understood that, the antenna module in the embodiment of the present disclosure is located on a conductive sheet, which can reduce the mutual interference caused by the change of the distance between multiple antennas when the terminal device moves or the posture changes, and can improve the communication quality of the antenna module. Moreover, when the antenna radiator of one antenna is at least part of one conducting strip, the situation that connection among a plurality of conducting strips is unstable due to the fact that one antenna radiator corresponds to a plurality of conducting strips can be reduced, and the stability of receiving and sending signals can be improved;
a plurality of antenna radiation bodies at a plurality of antennas comprise the different regions of conducting strip, when a common conducting strip of a plurality of antenna radiation bodies promptly, can increase the radiating area of single antenna radiation body, improve the radiation efficiency and the radiation bandwidth of antenna radiation body, reduce the condition that antenna radiation body receives the environmental impact, simultaneously can also only need a conducting strip, and need not set up a plurality of conducting strips alone and realize the wireless signal of a plurality of frequency channels of receiving and dispatching, and then can reduce the space that the antenna module occupy terminal equipment, improve terminal equipment's space utilization. In addition, the plurality of antenna radiating bodies share one conducting strip, so that the positions among different antenna radiating bodies are more stable, and the reliability of the arrangement of the plurality of antenna radiating bodies is improved.
In some embodiments, as shown in fig. 7, there are openings 103 between different regions on the conductive sheet;
the opening 103 is located between two adjacent antenna radiators 102.
That is, adjacent two of the plurality of antenna radiators are separated by an opening.
In the embodiment of the present disclosure, the number of the openings is the same as the number of the antenna radiators in the antenna module. For example, the number of the antenna radiators and the number of the openings in the antenna module are three or four, and the embodiments of the present disclosure are not limited.
It should be noted that the edge of the opening is a straight line, not a circular arc or a curved line. Therefore, the difficulty and error rate of opening manufacture can be reduced, and the efficiency of opening manufacture is improved.
In some embodiments, the opening does not intercept the connection between the different regions, and the opening width is associated with a frequency of a radiation signal of two adjacent antenna radiators.
In the disclosed embodiment, the resonant frequency of the antenna radiator radiation signal is inversely related to the length of the connection between the different areas that are not interrupted by the opening. For example, the length at which the resonance frequency is high is smaller than the length at which the resonance frequency is high.
It should be noted that, when the resonant frequency of the radiation signal of the antenna radiator is within the radiation frequency band range of the antenna radiator, the interference between two adjacent antenna radiators is small, so that the isolation between two adjacent antenna radiators can meet the requirement of the antenna module.
When the antenna radiators transmit and receive wireless signals, the energy of one antenna radiator in the two adjacent antenna radiators enters the other antenna radiator, which not only causes radiation energy loss, but also causes interference to the adjacent antenna radiators. Usually, the isolation needs to be more than 15dB to meet the use requirement of the antenna radiator.
As shown in fig. 8 and 9, in the related art, three conductive sheets spaced 1 mm apart from each other are provided on a substrate 201, and the three conductive sheets are used as three antenna radiators 202 to radiate wireless signals. It can be seen from fig. 9 that the minimum frequency point of the isolation between the three conductive sheets as antenna radiation is only 12dB, and the requirement that the isolation exceeds 15dB cannot be met.
As shown in fig. 10, in the embodiment of the present disclosure, by providing the opening and adjusting the length of the opening not to cut off the connection between different regions, the isolation of the antenna radiator is greater than 20dB, and the use requirement of the isolation can be satisfied.
It can be understood that, in the embodiments of the present disclosure, the isolation between the antenna radiators is no longer improved by increasing the physical size between the antenna radiators, but is improved by setting the opening not to cut off the connection length of different areas, so that the space occupied by the conductive sheet on the terminal device can be reduced while the isolation of at least two antenna radiators meets the requirement.
In some embodiments, as shown in fig. 7, the antenna module further includes:
a radio frequency front end component;
a feed point, wherein one of the antenna radiators has two feed points located on the conductive sheet, and the two feed points of the same antenna radiator include: a first feeding point 104 and a second feeding point 104;
the first feeding point 104 is connected to the rf front-end component;
the second feeding point 105 is connected to ground.
That is, the same antenna radiator in the antenna module has two feeding points, and the two feeding points are two different and independent feeding points.
The first feed point is connected with the radio frequency front end component and used for transmitting a first electric signal obtained by converting the antenna radiation body to the radio frequency front end component so as to realize subsequent processing such as receiving wireless signals, decoding signals and the like; or, the second electrical signal generated by the radio frequency front end component is transmitted to the antenna radiator, so that the antenna radiator radiates the wireless signal under the excitation of the second electrical signal. The second feeding point is connected with the ground wire and used for forming a current loop and refluxing the first electric signal on the antenna radiator to the ground.
In the embodiment of the disclosure, the first feeding point and the second feeding point are arranged on the conductive sheet at intervals. The conducting strip is connected with the first feeding point and the second feeding point through soldering tin.
In the disclosed embodiment, the first feeding point and the second feeding point may be connected to one coaxial feed line. The central wire of the coaxial feeder is connected with the first feeding point, and the peripheral wire positioned on the periphery of the central wire in the coaxial feeder is connected with the second feeding point. In some embodiments, the distance between the first and second feed points is the same as the distance between the outer and center conductors in the coaxial feed line. Thus, different functions of the two feeding points can be realized through one coaxial feeder.
It should be noted that the radio frequency front end component includes a first amplifier, an antenna switch, a filtering component, a duplexer, and a second amplifier. The first amplifier is used for amplifying the electric signal in the signal output channel. The antenna switch is used for realizing the switching between the receiving of the electric signal and the transmitting of the electric signal and the switching between different frequency bands of the antenna. The filter is used for filtering signals outside the specific frequency band through the signals of the specific frequency band. The duplexer is used for isolating the transmitted electric signal and the received electric signal, so that the antenna can normally work when receiving and transmitting wireless signals simultaneously. The second amplifier is used for realizing the electric signal amplification of the signal receiving channel. Therefore, the radio frequency front end component can receive and transmit electric signals, and the radiating body can better receive and transmit wireless signals.
In some embodiments, the antenna module further comprises:
a coaxial feed line, comprising: a central wire and a peripheral wire surrounding the central wire, wherein the central wire and the peripheral wire have the same axial center;
the first feed point is connected with the radio frequency front end component through the central lead;
and the second feeding point is connected with the ground wire through the peripheral wire.
That is to say, the antenna module can realize different connections of two feed points of the same antenna radiator through one coaxial feeder, can reduce the number of feeders required for connecting different feed points, and can also reduce the space for setting a plurality of feeders to occupy the terminal equipment.
In some embodiments, as shown in fig. 7, the antenna radiator has a slot 106 on the conductive sheet;
the first feeding point 104 and the second feeding point 105 are respectively located on two opposite slot walls of the slot 106.
So, through setting up two feed points respectively on two relative trench walls, can realize setting up two feed points at the interval on the antenna radiator, and then can realize the independent function of two feed points.
In the disclosed embodiment, a connection line between the first feeding point and the second feeding point may be parallel to the groove bottom of the groove. That is, the distance between the first feeding point and the second feeding point is the slot distance between two oppositely disposed slot walls in the slot.
It should be noted that the first feeding point is connected to the central conductor, and the second feeding point is connected to the peripheral conductor. The width of the coaxial feed line is positively correlated with the slot pitch. For example, the slot pitch of the coaxial feed line width is larger than the slot pitch of the coaxial feed line narrow.
In some embodiments, as shown in FIG. 7, the grooves 106 are T-shaped.
In the embodiments of the present disclosure, the shape of the groove is not limited to be T-shaped. The groove can also be L-shaped or cross-shaped.
It can be understood that the antenna radiator with the T-shaped groove obtained through simulation verification can reduce the lowest transceiving frequency in the radiation frequency band, and thus can improve the radiation bandwidth of the antenna radiator.
In the embodiment of the present disclosure, the edges of the conductive sheets are all straight lines, rather than circular arcs or curves. Therefore, compared with the conducting plate which is set to be in a planar equiangular spiral shape and an Archimedes spiral shape, the conducting plate with the edge being in a straight line in the embodiment of the disclosure can reduce the difficulty and error rate of the conducting plate manufacture and improve the manufacture efficiency.
In some embodiments, two adjacent antenna radiators transmit and receive wireless signals with different center frequencies.
It can be understood that, by enabling two adjacent antenna radiators to receive and transmit wireless signals with different center frequencies, mutual interference of the two adjacent antenna radiators in receiving and transmitting the wireless signals at the same time can be reduced, and then isolation between the antenna radiators can be improved.
In some embodiments, as shown in fig. 7, the antenna module is an ultra-wideband antenna module, including: three ultra-wideband antennas;
three antenna radiators 102 of the three ultra-wideband antennas are distributed in a delta shape.
It can be understood that the antenna module is set to be an ultra-wideband antenna module, so that the conducting strip is simple in structure and easy to construct, and meanwhile, the performance of the antenna can be improved.
In some embodiments, the antenna module further comprises:
and the conducting wire is connected between the two spaced radiation arms in the antenna radiator.
In the embodiment of the present disclosure, the wire is used to connect two radiating arms, and a direct current path can be formed between the two radiating arms through the wire to achieve the discharge of static electricity. That is to say, in the antenna radiator in the embodiment of the present disclosure, the static electricity is discharged through the dc loop of the antenna radiator itself by means of dc grounding, instead of discharging through the electrostatic discharge tube. So, under the condition of reducing the damage of static to radio frequency front end subassembly in the antenna module, can reduce because of setting up the static discharge tube that leads to and occupy the big condition in terminal equipment space, improved terminal equipment's space utilization.
It should be noted that the embodiments of the present disclosure are not limited to connecting two radiating arms through wires, and may also connect two radiating arms through conductors. The conductor includes a conductive sheet. The conductive sheet may be of a metal or alloy material.

Moreover, when the antenna radiator of one antenna is at least part of one conducting strip, the situation that connection among a plurality of conducting strips is unstable due to the fact that one antenna radiator corresponds to a plurality of conducting strips can be reduced, and the stability of receiving and sending signals can be improved;
the antenna radiator at a plurality of antennas comprises the different regions of conducting strip, when a common conducting strip of a plurality of antenna radiators promptly, can increase the radiating area of single antenna radiator, improve the radiation efficiency and the radiation bandwidth of antenna radiator, reduce the condition that antenna radiator received the environmental impact, can only need a conducting strip simultaneously, and need not set up a plurality of conducting strips alone and realize the wireless signal of a plurality of frequency channels of receiving and dispatching, and then can reduce the space that the antenna module occupy terminal equipment, improve terminal equipment's space utilization.
