Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
In order to better adapt to a smaller antenna clearance environment provided by the conventional electronic equipment, the application provides the electronic equipment, so that the occupation amount of the antenna on the equipment clearance is reduced by supporting multi-band coverage on different communication networks on one antenna.
Fig. 1 illustrates a component structure of an electronic device disclosed in the present application, and as shown in fig. 1, in an embodiment, the electronic device at least includes:
one antenna 10;
the one antenna 10 at least comprises a first subsegment 101 and a second subsegment 102;
wherein:
a first sub-segment 101, configured to support coverage of a first frequency band and a second frequency band based on generation of resonance of the first frequency band and the second frequency band, where a frequency corresponding to the first frequency band is lower than a frequency corresponding to the second frequency band;
a gap is arranged between one end of the second subsection 102 and the first end of the first subsection 101, and is used for supporting the coverage of a third frequency band under the excitation of the first end of the first subsection 101;
and the frequency corresponding to the second frequency band is lower than the frequency corresponding to the third frequency band.
The first frequency band and the second frequency band may be, but not limited to, a low frequency band and an intermediate frequency band of 4G LTE (Long Term Evolution), a low frequency band and an intermediate frequency band of 3G WCDMA (Wideband Code Division Multiple Access), or a low frequency band and an intermediate frequency band of 2G GSM (Global System for Mobile communications), respectively, and are not limited herein.
The third frequency band may be, but is not limited to, an N78 frequency band of 5G NR (New Radio, New air interface).
Specifically, referring to fig. 2, a first sub-segment 101 and a second sub-segment 102 are formed by slotting at corresponding positions of the antenna 10, and a slot formed by the slotting is a slot between one end of the second sub-segment 102 and a first end of the first sub-segment 101. In the embodiment of the present application, an end point of the first end of the first sub-segment corresponding to the gap is referred to as an open end of the first sub-segment, and an end point of the second sub-segment corresponding to the gap is referred to as an open end of the second sub-segment.
In order to generate the resonance of the first frequency band and the second frequency band in the first sub-section 101, in the embodiment of the present application, the first sub-section is configured to be an inverted F-shape, as shown in fig. 2, the inverted F-shaped first sub-section 101 includes a first branch, a second branch, and a third branch, where:
with further reference to fig. 2, the first branch and the second branch are located at the same side of the third branch and are connected to different ends of the third branch, respectively; and the second ends of the first branch and the second branch which are not connected with the third branch meet a first parallel condition, the second ends of the first branch and the second branch respectively meet a vertical condition with the third branch, and the distance between the second end of the second branch and the first branch is smaller than the distance between the third end of the second branch and the first branch.
The second end of the first branch and the second branch, which is not connected to the third branch, satisfies the first parallel condition, and specifically, the first branch is parallel to the second end, or the first branch is approximately parallel to the second end, that is, an absolute value of a difference between an included angle of the first branch and the second branch and 180 ° is smaller than a threshold.
Similarly, the second ends of the first branch and the second branch respectively satisfy the perpendicular condition with the third branch, which may mean that the second ends of the first branch and the second branch are respectively perpendicular to the third branch, or the second ends of the first branch and the second branch are respectively approximately perpendicular to the third branch, that is, the absolute value of the difference between the second ends of the first branch and the second branch and the third branch and 180 ° is less than the threshold.
In addition, a feeding point for feeding the antenna feeding circuit is arranged at the joint of the third branch and the second branch, and an antenna place for grounding is arranged at the corresponding position of the second tail end of the second branch. By providing a feed point and a location for the above-described overall antenna structure comprising the individual sub-sections, the individual sub-sections constitute essentially one antenna, i.e. the antenna 10.
It should be noted that in the embodiments of the present application, "one end" specifically refers to an end point of a certain sub-segment or a certain branch in the sub-segment of an antenna; the term "end" refers to a small length (which may be configured according to actual circumstances) of a radiator at which a corresponding end of a sub-section or a branch in a sub-section of the antenna is located.
For better radiation of low frequencies, it is preferable that the distance value of the feeding point from the open end of the first sub-section is in the range of 45-48 mm, and the distance value of the feeding point from the position is in the range of 10-14 mm.
Based on the above-mentioned structure of the antenna 10, in the antenna 10, the first frequency band (low frequency band) and the second frequency band (intermediate frequency band) share the first sub-segment 101 as a radiator, the first sub-segment 101 at least partially supports the coverage of the first frequency band and the second frequency band by generating low frequency resonance and intermediate frequency resonance, and in the above-mentioned antenna structure, the second sub-segment 102 is disposed along the first branch direction of the first sub-segment, and accordingly constitutes a parasitic branch to the first sub-segment 101, belonging to the first sub-segment 101, and the first sub-segment 101 excites the parasitic branch to generate a third frequency band, such as N78 frequency band generating 5G NR, by generating excitation at the first end adjacent to the end of the parasitic branch (the second sub-segment 102).
Taking the first frequency band and the second frequency band as the low frequency and the intermediate frequency band of 4G LTE, respectively, and the third frequency band as the N78 frequency band of 5G NR, the antenna structure described above can enable one antenna to support coverage of three frequency bands, i.e., the low frequency and the intermediate frequency band of 4G LTE and the N78 frequency band of 5G NR.
The low-frequency band of the 4G LTE is 600-960MHZ, however, the applicant finds, through research, that the antenna can only cover the low-frequency band with a bandwidth of about 100M, because the headroom of the current antenna is smaller and smaller, for example, a full-screen mobile phone can bring better user experience ID (Industrial Design) Design although the full-screen has an ultra-high screen occupation ratio, but the full-screen also brings negative influence to the mobile phone antenna, reduces the headroom of the antenna, and affects the directivity of the antenna. In terms of frequency bands, the longer the antenna is, the lower frequency band can be covered, and the high frequency band has low requirements on the size of the antenna. So once the antenna space is squeezed, the most affected is the low frequency, narrowing the bandwidth.
In this regard, in order to achieve overall coverage of the low frequency band and improve the low frequency bandwidth, referring to fig. 3, the electronic device of the present application further includes a switching circuit 20, where the switching circuit 20 is connected between two ends of the third branch of the first subsection 101, and is configured to switch the first subsection 101 of the antenna to cover different sub-bands of the first frequency band at different times.
Specifically, the switching circuit 20 includes a plurality of parallel-connected switching branches, each switching branch includes a switch and an inductor connected in series, and different switching branches include different inductors; one end of each change-over switch branch is connected between two ends of the third branch of the first subsection, and the other end of each change-over switch branch is grounded. The switching circuit 20 changes the coverage of the first sub-section to different sub-bands of the first frequency band (low frequency band) by controlling the closed states of the different switches.
In implementation, the frequency interval ranges of the plurality of different sub-bands included in the first frequency band may have partial overlap or no overlap, which may be determined by antenna efficiency corresponding to different inductors, and each sub-band may be set to a bandwidth of about 100M, but is not limited to be switched between different inductors by using a switching circuit, so as to implement time-sharing coverage of the different sub-bands of the low frequency, and accordingly achieve the purpose of comprehensively covering the low frequency band.
The distance between the switching circuit 20 and the ground is smaller than the distance between the switching circuit 20 and the feeding point, and the proximity condition is satisfied between the switching circuit 20 and the first end of the first subsection 101.
The condition that the switching circuit 20 and the first end 101 meet the proximity condition may specifically mean that a distance between the switching circuit 20 and the open end of the first sub-segment 101 does not exceed a set distance threshold, so that the switching circuit 2 is as close as possible to the open end of the first sub-segment 101.
In this embodiment, when setting the position of the switching circuit 20, the following factors are mainly considered:
1) the circuit switch does not influence frequency bands except for low frequency as much as possible so as to ensure better coverage bandwidth;
2) the closer the circuit switch is to the feed point, the better the radiation efficiency of the low frequency is, but the coverage range of the low frequency is small when the inductance is switched;
3) the farther the circuit switch is away from the feeding point, the poorer the radiation efficiency of the low frequency is, and the coverage range of the low frequency is increased, but the low frequency is more sensitive when the inductor is switched, and the low frequency cannot be covered more comprehensively.
In view of the above factors, in the implementation, it is preferable to set the switching circuit 20 as close as possible to the open end of the first sub-segment and about 13mm away from the feeding point. Based on the position setting, the high-middle frequency and the N78 frequency band can be basically unaffected in the process of low-frequency switching.
As can be seen from the above solutions, the electronic device disclosed in this embodiment only includes one antenna, where the one antenna at least includes a first subsegment and a second subsegment, where the first subsegment is configured to support coverage of a first frequency band and a second frequency band based on generation of resonances of the first frequency band and the second frequency band, and a gap is provided between one end of the second subsegment and a first end of the first subsegment, and is configured to support coverage of a third frequency band under excitation of the first end; the frequency corresponding to the first frequency band is lower than the frequency corresponding to the second frequency band, and the frequency corresponding to the second frequency band is lower than the frequency corresponding to the third frequency band. Therefore, the coverage of different communication frequency bands is supported by one antenna, so that the number of the antennas is reduced under the condition of ensuring multi-frequency band coverage, the space occupation amount is correspondingly reduced, the antenna can be better adapted to the smaller antenna clearance environment of the current equipment, and the mutual influence among different antennas in a multi-antenna setting mode is avoided.
Optionally, in an embodiment, referring to a schematic structural diagram of the electronic device shown in fig. 4, in the electronic device disclosed in the present application, the above-mentioned one antenna 10 further includes: a third sub-section 103.
The third sub-section 103 has a gap with an end point of the third branch of the first sub-section 101 corresponding to the feeding point, and the third sub-section 103 is coupled to the feeding point for obtaining excitation based on the coupling with the feeding point to support the coverage of the fourth frequency band. The present embodiment refers to an end of the third sub-section 103 located at the gap as an open end of the third sub-section.
Specifically, the third sub-segment 103 is arranged along the third branch direction of the first sub-segment 101; the first sub-section 101, the second sub-section 102 and the third sub-section 103 form an Inverted-F antenna, i.e. the antenna is in the form of an IFA (Inverted-F antenna).
And the frequency corresponding to the fourth frequency band is higher than the frequency corresponding to the second frequency band and lower than the frequency corresponding to the third frequency band.
Optionally, the first frequency band, the second frequency band, and the fourth frequency band are respectively a low frequency band, an intermediate frequency band, and a high frequency band of 4G LTE, and the third frequency band is an N78 frequency band of 5G NR, so that coverage of the low, intermediate, and high frequency bands of 4G LTE and the N78 frequency band of 5G NR on one antenna is achieved.
In the above antenna structure, the third sub-segment 103 is arranged along the third branch direction of the first sub-segment 101, so that the third sub-segment 103 is also used as a parasitic branch of the first sub-segment 101, and the parasitic branch frame near the feeding point is excited to generate high frequency by fully utilizing the coupling of the feeding point to the parasitic branch, thereby correspondingly realizing the coverage of the fourth frequency band.
Further, in the present application, optionally, a branch of the third sub-section 103 arranged along the third branch direction of the first sub-section 101, that is, the above-mentioned parasitic branch coupled to the feeding point, is a main branch of the third sub-section 103.
The third subsection 103 further comprises an auxiliary branch for enhancing the coupling between the main branch of the third subsection 103 and the feeding point. The coupling between the main branch of the third subsection 103 and the feed point can thus be enhanced on the basis of the auxiliary branch, and accordingly the coverage of the fourth frequency band (the high frequency band of 4G LTE) can be better supported.
The auxiliary branch is connected to the feeding point and the auxiliary branch and the main branch of the third subsection 103 satisfy a second parallel condition.
The auxiliary branch and the main branch of the third subsection 103 satisfy the second parallel condition, and specifically, the auxiliary branch and the main branch are parallel, or the auxiliary branch and the main branch are approximately parallel, that is, an absolute value of a difference between an included angle between the auxiliary branch and the main branch and 180 ° is smaller than a threshold.
In the structure of an antenna included in the electronic device of the present application, the first frequency band and the second frequency band share the first sub-segment 101 of the antenna as a radiator, specifically as shown in fig. 5, the third frequency band uses the second sub-segment 102 and the first end of the first branch of the first sub-segment 101 as a radiator, specifically as shown in fig. 6, and the fourth frequency band uses the main branch and the auxiliary branch of the third sub-segment 103 as radiators, specifically as shown in fig. 7.
Further, referring to fig. 8, a schematic diagram of a radiator and a surface current in a first frequency band (low frequency) is provided, where an antenna portion corresponding to a line segment with an arrow is the radiator in the first frequency band, and a direction (except for an arrow at a feeding point) pointed by the arrow of the line segment is a surface current direction of the radiator in the first frequency band, specifically, in the example of fig. 8, a low frequency resonance is generated by a quarter wavelength of the low frequency radiator corresponding to an open end to a ground of the first sub-segment and a corresponding open end to the feeding point of the first sub-segment, and the low frequency resonance is supported by combining with a switching circuit. In addition, regarding the radiators and the surface currents of the second frequency band (intermediate frequency), the fourth frequency band (high frequency), and the third frequency band (N78), specific reference may be made to fig. 9, fig. 10, and fig. 11, respectively, and no description is given once again.
In the embodiment of the present application, the switching circuit is disposed at corresponding positions of the radiators of the low frequency (first frequency band) and the medium frequency (second frequency band), so that switching of the switch in the switching circuit has substantially no influence on the high frequency (fourth frequency band) and the N78 frequency band (third frequency band). When different inductors are switched by using a switch, the change of low frequency is more sensitive, and the change of intermediate frequency is very small, so that the influence on intermediate frequency, high frequency and N78 frequency bands is very small when the inductors are switched, thereby satisfying the requirement that one antenna simultaneously supports low, medium and high + N78 frequency bands and ensuring the coverage performance of each frequency band.
Referring to fig. 12, the system efficiency and radiation efficiency of the present application are provided when the switching circuit is in the open state when the device antennas are not matched. The uppermost curve represents the antenna radiation efficiency of the switching circuit in the open state, the low-frequency radiation efficiency is-2.5 to-3.5 dB, the medium-high frequency radiation efficiency is-0.5 to-1.5 dB, the N78 radiation efficiency is-1.5 to-3 dB, and the other curves represent the antenna system efficiency of the switching circuit in the open state.
The antenna is not matched, which means that the feeding point is directly connected to the feeding circuit without passing through the matching circuit.
Further referring to fig. 13 and 14, respectively, an antenna in the electronic device of the present application is shown, where when the return loss of the free space of the antenna and Smith chart (Smith chart, also called Smith chart) are not matched, that is, fig. 13 specifically shows the return loss of the switching circuit in the open state, and fig. 14 specifically shows the Smith original image of the switching circuit in the open state when the antenna is not matched. In addition, performance information in terms of return loss and system efficiency after antenna free space matching (feeding point is connected to feeding circuit through matching circuit) in the present application is shown in fig. 15 and fig. 16, respectively, where fig. 15 specifically provides return loss when different inductances are introduced based on switching circuit after antenna matching, and fig. 16 provides system efficiency when different inductances are introduced based on switching circuit after antenna matching, where low frequency efficiency is above-5 dB, medium and high frequency efficiency is above-3 dB, and n78 efficiency is above-4 dB. Based on the drawings, the antenna has good antenna performance in terms of return loss and system efficiency.
In addition, in an implementation, the electronic device of the present application further includes a motherboard and a communication module.
The communication module is arranged on the mainboard and is connected with the antenna through the feed circuit.
Corresponding to the coverage of one antenna on multiple frequency bands, such as the coverage on the N78 frequency band of the 4G LTE low, medium and high frequency band +5G NR, the communication module may correspondingly include a 4G LTE communication module and a 5G NR communication module, which are respectively connected to the same antenna through a feeding circuit and specifically connected to a feeding point of the same antenna. Therefore, the electronic equipment realizes that the number of the antennas is reduced by utilizing one antenna to cover different communication frequency bands, the space occupation amount of the electronic equipment is correspondingly reduced, the electronic equipment is better suitable for a smaller antenna clearance environment of the current equipment, and the mutual influence among different antennas in a multi-antenna setting mode is avoided.
