Technical Field
[0001] The present invention relates to the field of antennas, and in particular to a 5G mobile phone diversity antenna covering B32. Background Art
[0002] With the emergence of a large number of 5G mobile phones, there are more and more communication antennas in mobile phones. For the conventional FPC mobile phone antenna form, there will be 9 antennas to meet a good communication experience. With the increasing communication requirements of mobile phone users, there will be a demand to add a B32 frequency band, that is, 1450-1500Mhz, on the basis of the original low, medium and high frequencies (600-960Mhz, 1710-2170Mhz, 2300-270Mhz). In addition to receiving signals, mobile phone communications also have high requirements for transmission performance. It is very difficult to debug a diversity antenna with B32 using conventional routing. Therefore, it is urgent to launch a mobile phone antenna and solution that optimizes the intermediate frequency resonance of the diversity antenna. At present, the technical diversity antenna does not have the B32 frequency band. If the frequency band B32 is added, the existing technology B32 cannot cover it. At this time, we need a new technical solution to cover B32.
[0003] 5G mobile phone antennas, as users' communication experience requirements become higher and higher, often need to add the rare frequency band B32 (1450-1500Mhz) to the conventional intermediate frequency (1710-2170Mhz), and this frequency band is often placed on the diversity antenna, which is better because the diversity antenna is often designed to be directly above the mobile phone, and the main antenna is generally placed directly below the mobile phone. If the B32 is placed on the main antenna, the performance of the B32 will be greatly attenuated when held by human hands, so the B32 frequency band is generally placed on the diversity antenna directly above the mobile phone. In view of this, the technical problem solved by the present invention is to provide a 5G mobile phone diversity antenna covering B32. Summary of the invention
[0004] The purpose of the present invention is to provide a 5G mobile phone diversity antenna covering B32 to solve the problems raised in the above-mentioned background technology. It has the advantage of achieving a performance breakthrough of diversity B32 while taking into account the performance of low intermediate frequency.
[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a 5G mobile phone diversity antenna covering B32, comprising an antenna body, a feeding point and a grounding point are arranged on the antenna body, a low-frequency branch is arranged at the upper end of one side of the antenna body, a high-frequency branch is arranged at the lower end, a first intermediate frequency branch is arranged on the other side of the antenna body, a second intermediate frequency branch is arranged at one end of the first intermediate frequency branch away from the second intermediate frequency branch, a first fine groove is arranged at the connection between the antenna body and the first intermediate frequency branch, and a second fine groove connected to the first fine groove is arranged above the first intermediate frequency branch.
[0006] By adopting the above technical solution, the first fine groove reasonably distributes the low-frequency branch, the first intermediate frequency branch and the second intermediate frequency branch. If the 5G mobile phone diversity antenna carries the B32 frequency band, it is equivalent to covering the entire intermediate frequency (1450-2170MHZ). To achieve this coverage rate with existing technology, the wiring area must be large enough. However, there are many 5G mobile phone antennas, and each antenna needs to occupy a corresponding area. The distance must be controlled during debugging, otherwise the isolation is not good or the antenna area is not arranged reasonably, which will affect the overall performance of the mobile phone. The diversity antenna area will not be given a particularly large area, and there will be other antennas around it, which will cause the antennas to be directly close to each other. The advantage of the present invention is that when the antenna area is limited and the antenna clearance environment is relatively poor, the diversity antenna can achieve the switching of the entire medium and high frequency (1450-2700MHZ) and cover the B32 frequency band.
[0007] As a further solution of the present invention: a through slot is provided between the feeding point and the grounding point.
[0008] By adopting the above technical solution, the through slot controls the bandwidth of the low frequency.
[0009] As a further solution of the present invention: the thickness of the first intermediate frequency branch is thickened until the intermediate frequency resonance is lengthened to 1450-1500Mhz.
[0010] By adopting the above technical solution, the length of the second intermediate frequency branch has reached its limit due to the presence of other antennas on the side, but the intermediate frequency is still not long enough, so the width of the first intermediate frequency branch must be thicker, because this branch mainly controls the length and bandwidth of the intermediate frequency. The wide and thick form can ensure that the intermediate frequency resonance can be extended to B32 (1450-1500Mhz) while taking into account the bandwidth. This can ensure the performance of B32 and take into account other intermediate frequencies. While adding the new frequency band B32, other frequency bands are also normal, ensuring a good communication experience for users.
[0011] Preferably, the first intermediate frequency branch and the second intermediate frequency branch are arranged obliquely.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. The disadvantage of the prior art is that when the diversity antenna has a B32 frequency band requirement, the intermediate frequency routing can only be forcibly lengthened to achieve the switch switching of B32. However, since the low intermediate frequency is highly correlated, adding routing generally makes part of the low intermediate frequency extremely poor. The purpose of the present invention is to achieve a performance breakthrough of diversity B32 on the basis of taking into account the performance of the low intermediate frequency when there is a B32 frequency band;
[0014] 2. It can debug the B32 frequency band with good efficiency, and the low and medium frequency performance is also very good, which perfectly solves the disadvantage that the existing technology cannot cover B32;
[0015] 3. If the 5G mobile phone diversity antenna carries the B32 frequency band, it is equivalent to covering the entire intermediate frequency (1450-2170MHZ). To achieve this coverage rate with existing technology, the routing area must be large enough. However, 5G mobile phones have many antennas, and each antenna needs to occupy a corresponding area. The distance must be controlled during debugging, otherwise the isolation is not good or the antenna area is not arranged reasonably, which will affect the overall performance of the mobile phone. The diversity antenna area will not be particularly large, and there will be other antennas around it, which will cause the antennas to be relatively compact. The advantage of the present invention is that when the antenna area is limited and the antenna clearance environment is relatively poor, the diversity antenna can achieve the switching of the entire intermediate and high frequencies (1450-2700MHZ) and cover the B32 frequency band;
[0016] 4. For 5G diversity antenna, there is no other alternative solution at present, because 5G mobile phone FPC antenna generally has 9 antennas to meet the user's communication experience. The diversity antenna area and wiring range are relatively limited. In addition, the motherboard diversity clearance environment is not very good due to the structure of the mobile phone, so this technical solution can only be used to better achieve B32 coverage;
[0017] 5. This new antenna has overcome the problem that the current 5G mobile phone diversity antenna cannot cover the B32 frequency band. The figure clearly shows that 9 important branches are linked together. The most critical point is the opening method of the first slot and the second slot. While achieving B32 coverage, the performance of other frequency bands is also taken into account. Moreover, B32 is placed on the diversity antenna. The diversity antenna is generally located above the mobile phone, and the head-hand performance is less reduced. This also greatly improves the communication experience of 5G mobile phone users when making calls. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0021] In the embodiment of the present invention,
[0022] A 5G mobile phone diversity antenna covering B32, comprising an antenna body, wherein a feeding point and a grounding point are arranged on the antenna body, a low-frequency branch is arranged at the upper end of one side of the antenna body, and a high-frequency branch is arranged at the lower end, a first intermediate frequency branch is arranged on the other side of the antenna body, a second intermediate frequency branch is arranged at one end of the first intermediate frequency branch away from the second intermediate frequency branch, a first fine groove is arranged at the connection between the antenna body and the first intermediate frequency branch, and a second fine groove connected to the first fine groove is arranged above the first intermediate frequency branch.
[0023] A through slot is provided between the feeding point and the grounding point.
[0024] The thickness of the first intermediate frequency branch is thickened until the intermediate frequency resonance is lengthened to 1450-1500Mhz.
[0025] The first intermediate frequency branch and the second intermediate frequency branch are arranged obliquely.
[0026] Working principle:
[0027] The disadvantage of the prior art is that when the diversity antenna has a B32 frequency band requirement, the intermediate frequency routing can only be forcibly lengthened to achieve the switching of B32. However, since the low intermediate frequency is highly correlated, adding routing will generally make part of the low intermediate frequency extremely poor. The purpose of the present invention is to achieve a performance breakthrough of diversity B32 while taking into account the performance of the low intermediate frequency when there is a frequency band B32.
[0028] The B32 frequency band with high efficiency can be debugged, and the low and medium frequency performance is also very good, which perfectly solves the disadvantage that the existing technology cannot cover B32.
[0029] If the 5G mobile phone diversity antenna carries the B32 frequency band, it is equivalent to covering the entire intermediate frequency (1450-2170MHZ). To achieve this coverage rate with existing technology, the routing area must be large enough. However, there are many 5G mobile phone antennas, and each antenna needs to occupy a corresponding area. The distance must be controlled during debugging, otherwise the isolation is not good or the antenna area is not arranged reasonably, which will affect the overall performance of the mobile phone. The diversity antenna area will not be given a particularly large area, and there will be other antennas around it, which will cause the antennas to be directly close to each other. The advantage of the present invention is that when the antenna area is limited and the antenna clearance environment is relatively poor, the diversity antenna can achieve the switching of the entire intermediate and high frequency (1450-2700MHZ) and cover the B32 frequency band.
[0030] There is currently no alternative to 5G diversity antennas, because 5G mobile phones generally have 9 FPC antennas to meet the user's communication experience. The diversity antenna area and wiring range are relatively limited. In addition, the motherboard diversity clearance environment is not very good due to the structure of the mobile phone, so this technical solution can only be used to better achieve B32 coverage.
[0031] This new antenna has overcome the problem that the current 5G mobile phone diversity antenna cannot cover the B32 frequency band. The figure clearly shows that 9 important branches are linked together. The most critical point is the opening method of the first slot and the second slot. While achieving B32 coverage, the performance of other frequency bands is also taken into account. Moreover, B32 is placed on the diversity antenna. The diversity antenna is generally located above the mobile phone, and the head-hand performance is less degraded. This also greatly improves the communication experience of 5G mobile phone users when making calls.
