In the related art, the upper hemisphere of the mobile phone-type mobile terminal is efficient, most of the 5G antennas are concentrated in the top area of the mobile terminal, and the number of the 5G antennas is very small only in the bottom area of the mobile terminal.

The antenna device is used for receiving and transmitting wireless signals of corresponding frequency bands, and is applied to the mobile terminal so that the mobile terminal can be connected to a wireless network through the antenna device. For example, the antenna device is applied to a mobile phone to receive a communication signal. The mobile phone is provided with a frame 10, wherein an upper half area of the frame 10 is a top area 101, and a lower half area is a bottom area 102.
As shown in fig. 1, the antenna device includes a frame 10, a first antenna group 20 and a second antenna group 30 disposed on the frame 10, where the first antenna group 20 and the second antenna group 30 are both provided with at least one communication antenna, the frame 10 includes a top area 101, and a bottom area 102 disposed opposite to the top area 101, the first antenna group 20 is disposed on the top area 101, and the second antenna group 30 is disposed on the bottom area 102, where an operating frequency band covered by the first antenna group 20 configured in the top area 101 is the same as an operating frequency band covered by the second antenna group 30 configured in the bottom area 102.
The first antenna group 20 includes one or more communication antennas, each capable of receiving communication signals in a corresponding operating frequency band. When the number of communication antennas is two or more, the two or more communication antennas are spaced apart at the top area 101. Similarly, the second antenna group 30 includes one or more communication antennas, and when the number of communication antennas is two or more, the two or more communication antennas are spaced apart from the bottom area 102.
The top region 101 and the bottom region 102 are relatively distributed on the frame 10, and the first antenna group 20 and the second antenna group 30 are relatively distributed on the frame 10. When one of the first antenna group 20 and the second antenna group 30 is affected by external interference to affect the transmission and reception of communication signals, the other of the first antenna group 20 and the second antenna group 30 can keep stable communication quality. The layout of the first antenna group 20 and the second antenna group 30 on the frame 10 is wide, and the working frequency bands received by the first antenna group 20 and the second antenna group 30 are the same, even if one of them is interfered by the communication caused by the holding of the hand of the user, the other can keep communication, and the user experience is good. The first antenna group 20 and the second antenna group 30 are respectively arranged in the top area 101 and the bottom area 102 of the frame 10, the communication antennas are arranged in the frame 10 in a scattered manner and can form approximately symmetrical layout on the working frequency band for receiving and transmitting communication signals, the layout is reasonable, mutual interference is small, and user experience is good.
In an embodiment, the frame 10 is a metal frame, and the communication antennas configured by the first antenna group 20 and the second antenna group 30 are disposed on the metal frame. The communication antennas included in the first antenna group 20 and the second antenna group 30 are disposed at the side walls of the metal frame, for example, the antenna body portion of the communication antenna is formed by grooving the metal frame, and the antenna body portion is connected to the corresponding antenna control module through signal lines. The communication antennas are directly arranged on the metal frame, so that the antenna cost can be reduced, the first antenna group 20 and the second antenna group 30 can be conveniently laid out at the position of the metal frame, and the mutual interference between the communication antennas is reduced. The communication antenna is directly arranged on the metal frame, and is improved by at least 1-2dB compared with an LDS antenna adopted by the antenna device, and the antenna communication performance is good.
The working frequency bands covered by the first antenna group 20 and the second antenna group 30 are the same, so that the first antenna group and the second antenna group can transmit and receive communication signals at the same time, and the transmitting and receiving strength of the communication signals is improved; or one of the first antenna group 20 and the second antenna group 30 transmits and receives communication signals to save energy of the mobile terminal. In an alternative embodiment, the first antenna group 20 and the second antenna group 30 are each capable of transceiving communication signals in the 5G operating band. For example, the first antenna group 20 is provided with two communication antennas, one of the 5G communication antennas can receive the 5G signal in the N41 frequency band, and the other 5G communication antenna can receive the 5G signal in the N78/N79 frequency band, so that the second antenna group 30 can also receive the 5G signals in the N41, N78, N79 frequency bands.
As shown in fig. 2 and fig. 4, the first antenna group 20 configured in the top area 101 and the second antenna group 30 configured in the bottom area 102 cover the same operating frequency band, and the number of communication antennas included in the first antenna group 20 may be the same as or different from the number included in the second antenna group 30. For example, different feeding modes of the same antenna body can receive communication signals of different 5G frequency bands, or a plurality of communication antennas of the same 5G frequency band are arranged.
In an alternative embodiment, the number of communication antennas of the first antenna group 20 configured by the top region 101 is the same as the number of communication antennas of the second antenna group 30 configured by the bottom region 102. For example, if the first antenna group 20 is provided with three communication antennas, the second antenna group 30 is also configured with three communication antennas, and the working frequency bands covered by the first antenna group 20 and the second antenna group 30 are the same. Optionally, the communication antennas of the second antenna group 30 are in one-to-one correspondence with the communication antennas of the first antenna group 20, that is, the communication antennas of the same working frequency band are configured in the second antenna group 30, so that the antenna devices form a layout similar to a symmetrical layout in space, and have less mutual interference and good communication stability.
For example, the first antenna group 20 is provided with three communication antennas, wherein one of the 5G communication antennas can receive the 5G signal in the N41 frequency band, one of the 5G communication antennas can receive the 5G signal in the N78/N79 frequency band, and the last 5G communication antenna can receive the 5G signal in the N41/N78/N79 frequency band. Correspondingly, the second antenna group 30 is also provided with three communication antennas, wherein one 5G communication antenna can receive 5G signals in the N41 frequency band, one 5G communication antenna can receive 5G signals in the N78/N79 frequency band, and the last 5G communication antenna can receive 5G signals in the N41/N78/N79 frequency band. Since the first antenna group 20 is disposed in the top region 101 and the second antenna group 30 is disposed in the bottom region 102, the first antenna group 20 and the second antenna group 30 are spatially similar to a symmetrical layout.
As shown in fig. 2, the working frequency bands covered by the first antenna group 20 and the second antenna group 30 are the same, so that the two antenna groups can simultaneously transmit and receive communication signals, and accordingly, part of the communication antennas in the first antenna group 20 and part of the communication antennas in the second antenna group 30 have the same working frequency band. In an alternative embodiment, the communication antennas in the same working frequency band in the first antenna group 20 and the second antenna group 30 are diagonally disposed on the frame 10, so that two communication antennas in the same working frequency band are respectively distributed at two ends of the frame 10 and are oppositely disposed.
In an alternative embodiment, as shown in fig. 3, the communication antennas in the same working frequency band in the first antenna group 20 and the second antenna group 30 are located on the same side of the frame 10, so that two communication antennas in the same working frequency band are respectively distributed at two ends of the frame 10 and are spaced apart from each other.
The two communication antennas in the same working frequency band are distributed at intervals or are arranged at opposite oblique angles, so that the probability that the two communication antennas in the same working frequency band are simultaneously held can be reduced, and the stability of communication signals is kept. For example, when the user's hand is held in the upper half of the cell phone, the communication antenna of the bottom region 102 is communicatively connected. When the user's hand is held in the lower half of the handset, the communication antenna of the top region 101 is communicatively connected. Optionally, when the mobile terminal detects that one of the communication antennas is held, resulting in a decrease in communication capability, the other communication antenna is activated as a main antenna for communication, and the antenna resources are allocated reasonably, so that the communication stability is maintained.
As shown in fig. 1 and 2, in one embodiment, the frame 10 includes a top frame 11, a bottom frame 12 disposed opposite to the top frame 11, and a first side frame 13 and a second side frame 14 disposed opposite to the top frame 11 and the bottom frame 12. The communication antennas of the first antenna group 20 are disposed at intervals between the top frame 11 and the first and second side frames 13 and 14 intersecting one end of the top frame 11, and the communication antennas of the second antenna group 30 are disposed at intervals between the bottom frame 12 and the first and second side frames 13 and 14 intersecting the other end of the top frame 11.
The top rim 10, the first side frame 13, the bottom rim 10 and the second side frame 14 are connected in sequence to form a closed annular rim 10 structure, for example, the rim 10 surrounds the rim 10 structure formed in a rectangular shape. Alternatively, the first side frame 13 and the second side frame 14 are divided at a middle portion such that the first side frame 13 and the second side frame 14 intersect to a portion of the top frame 10 at the top region 101 and another portion at the bottom region 102.
The top area 101 is formed by combining one end of the first side frame 13 and the second side frame 14 connected with the top frame 10, and the communication antennas of the first antenna group 20 can be distributed at any position of the top area 101. For example, the communication antenna is provided to the first side frame 13, the second side frame 14, or the top frame 10, or the communication antenna extends from the top frame 10 to the first side frame 13 or the second side frame 14. Similarly, the end of the first side frame 13 and the second side frame 14 connected to the bottom frame 10 forms a bottom area 102 in combination with the bottom frame 10, and the communication antennas of the first antenna group 20 may be distributed at any location in the bottom area 102. For example, the communication antenna is provided to the first side frame 13, the second side frame 14, or the bottom frame 10, or the communication antenna extends from the bottom frame 10 to the first side frame 13 or the second side frame 14.
In an alternative embodiment, as shown in fig. 2 and 3, the first antenna group 20 includes a first signal antenna 21 disposed on the top frame 11, the second antenna group 30 includes a second signal antenna 31 disposed on the bottom frame 12, and the first signal antenna 21 and the second signal antenna 31 have the same operating frequency band. The first signal antenna 21 and the second signal antenna 31 are disposed opposite to each other, so that interference between the two can be reduced, and the risk of lowering communication performance by holding the two at the same time can be reduced. For example, the first signal antenna 21 and the second signal antenna 31 can receive the 5G signal in the N41 frequency band, that is, both ends of the frame 10 can receive the 5G signal in the N41 frequency band without being held, and the 5G signal in the frequency band is stably received.
In an alternative embodiment, the first antenna group 20 includes a third signal antenna 22 disposed on the first side frame 13 or the second side frame 14, the second antenna group 30 includes a fourth signal antenna 32 disposed on the first side frame 13 or the second side frame 14, and the third signal antenna 22 has the same operating frequency band as the fourth signal antenna 32. Optionally, the third signal antenna 22 is disposed on the first side frame 13 in the top region 101, and the fourth signal antenna 32 is disposed on the first side frame 13 or the second side frame 14 in the bottom region 102. Optionally, the third signal antenna 22 is disposed on the second side frame 14 in the top region 101, and the fourth signal antenna 32 is disposed on the first side frame 13 or the second side frame 14 in the bottom region 102. The third signal antenna 22 and the fourth signal antenna 32 are oppositely arranged or distributed at intervals on one side of the first side frame 13 or the second side frame 14, so that mutual interference between the two can be reduced, and the risk of reducing communication performance when the two are held at the same time can be reduced. For example, the third signal antenna 22 and the fourth signal antenna 32 can receive the 5G signal in the N78/N79 frequency band, that is, the opposite sides of the frame 10 can both receive the 5G signal in the N78/N79 frequency band without being completely held, and the 5G signal in the frequency band is stably received.
In an alternative embodiment, the first antenna group 20 includes a fifth signal antenna 23 disposed on the first side frame 13 or the second side frame 14, the second antenna group 30 includes a sixth signal antenna 33 disposed on the first side frame 13 or the second side frame 14, and the fifth signal antenna 23 has the same operating frequency band as the sixth signal antenna 33.
Optionally, the fifth signal antenna 23 is disposed on the first side frame 13 in the top region 101, and the sixth signal antenna 33 is disposed on the first side frame 13 or the second side frame 14 in the bottom region 102. Optionally, the fifth signal antenna 23 is disposed on the second side frame 14 in the top region 101, and the sixth signal antenna 33 is disposed on the first side frame 13 or the second side frame 14 in the bottom region 102. The fifth signal antenna 23 and the sixth signal antenna 33 are oppositely arranged or spaced on one side of the first side frame 13 or the second side frame 14, so that mutual interference between the fifth signal antenna and the sixth signal antenna can be reduced, and the risk of being held at the same time and reducing communication performance can be reduced. For example, the fifth signal antenna 23 and the sixth signal antenna 33 can receive the 5G signal in the N41/N78/N79 frequency band, that is, the opposite sides of the frame 10 can receive the 5G signal in the N41/N78/N79 frequency band without being completely held, and the 5G signal in the frequency band is stably received.
