[0023] The scheme of the embodiment of the present application is described in detail below in conjunction with the drawings of the specification.

[0024] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

[0025] The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the previously associated objects are in an "or" relationship. In addition, "many" in this article means two or more than two. In addition, the term "at least one" in this article means any combination of at least two of any one or more of a plurality of, for example, including at least one of A, B, and C, can mean including any one or more elements selected from the set consisting of A, B and C.

[0026] See also Figure 1 , Figure 1 It is a schematic diagram of a framework of an embodiment of the terminal antenna 100 of the present application. The terminal antenna 100 includes: an antenna body 110; a first antenna port 120, the first antenna port 120 is connected to the ground end, and is used to realize wireless communication in a first frequency band; at least two second antenna ports 130; a switching switch 140, which is respectively connected to each second antenna port 130, and the switching switch 140 is used to switch the connection mode of each second antenna port 130 in response to a control signal, so as to switch to wireless communication in different second frequency bands, wherein each second frequency band is lower than the first frequency band.

[0027] In addition, the terminal antenna 100 is also connected to the radio frequency unit 101 and the control unit 102. The radio frequency unit 101 transmits radio frequency signals to the terminal antenna 100 so that the terminal antenna 100 has the ability of wireless communication. The switching switch 140 is also connected to the radio frequency unit 101 and the ground end. The connection mode of the second antenna port 130 is defined by whether the second antenna port 130 is connected to the radio frequency unit 101 and the ground end. The control unit 102 switches the connection mode of each second antenna port 130 by sending a control signal to the switching switch 140, and cooperates with the radio frequency unit 101 to realize wireless communication in the first frequency band and each second frequency band.

[0028] In some embodiments, when the first frequency band is between 300MHz and 3GHz, each second frequency band may be between 3MHz and 30MHz. Alternatively, when the first frequency band is between 3MHz and 30MHz, each second frequency band may be between 300kHz and 3MHz. Alternatively, the first frequency band and each second frequency band belong to the same frequency band, and the first frequency band belongs to the higher frequency band of the frequency band, and each second frequency band belongs to the lower frequency band of the frequency band. For example, the first frequency band and each second frequency band belong to the same frequency band between 300MHz and 3GHz, the first frequency band may be specifically 2500-2700MHz, and each second frequency band may be 700-960MHz. It can be understood that no specific limitation is made here as to the specific frequency bands to which the first frequency band and the second frequency band belong.

[0029] In some embodiments, at least two second antenna ports 130 include a third antenna port 131 and a fourth antenna port 132, and the switching switch 140 can be used to control the connectivity between the third antenna port 131 and the fourth antenna port 132 and the radio frequency unit 101. In the terminal antenna 100, the first antenna port 120 is set very close to the third antenna port 131 and the fourth antenna port 132, so that when the third antenna port 131 or the fourth antenna port 132 is connected to the radio frequency unit 101, the connected third antenna port 131 or the fourth antenna port 132 can generate voltage in the first antenna port 120 and be in operation by spatial coupling, so as to realize wireless communication in the first frequency band. Specifically, the terminal antenna 100 can be divided into the following three cases:

[0030] 1. When the third antenna port 131 is connected to the RF unit 101 and the fourth antenna port 132 is connected to the ground terminal by controlling the switching switch 140, the wireless communication is switched to the first category and the second frequency band. In this connection mode, the third antenna port 131 is in operation, the fourth antenna port 132 is in a grounded state, and is not connected to the RF unit 101. Under the spatial coupling of the third antenna port 131, the first antenna port 120 is also in operation. For example, when the first frequency band and the second frequency band are between 300 MHz and 3 GHz, the first category and the second frequency band may be 800-960 MHz, and the first frequency band may be 1710-2690 MHz, which meets the wireless communication conditions in most areas of Europe, Asia, and Africa;

[0031] 2. When the third antenna port 131 is connected to the RF unit 101 by the switching switch 140, and the fourth antenna port 132 is not connected to the ground terminal and the RF unit 101, the wireless communication is switched to the second category and the second frequency band. In this connection mode, the third antenna port 131 is in operation, and the fourth antenna port 132 is neither connected to the ground terminal nor to the RF unit 101. Therefore, the fourth antenna port 132 is in an empty state. Under the spatial coupling of the third antenna port 131, the first antenna port 120 is also in operation. For example, when the first frequency band and the second frequency band are between 300 MHz and 3 GHz, the second category and the second frequency band may be 700-900 MHz, and the first frequency band may be 1710-2690 MHz, which meets the wireless communication conditions in most areas of America and Australia.

[0032] 3. When the third antenna port 131 is controlled by the switching switch 140 to not be connected to the RF unit 101 and the ground, and the fourth antenna port 132 is connected to the RF unit 101, switch to the wireless communication of the third category and the second frequency band. In this connection mode, the third antenna port 131 is in an empty state, and the fourth antenna port 132 is in an operating state. Under the action of the spatial coupling of the fourth antenna port 132, the first antenna port 120 is also in an operating state. For example, when the first frequency band and the second frequency band are between 300 MHz and 3 GHz, the third category and the second frequency band can be 700-800 MHz, and the first frequency band is 1710-2690 MHz, which meets the wireless communication conditions in most areas of the Americas.

[0033] Among them, the second frequency band of the first category, the second frequency band of the second category, and the second frequency band of the third category have at least some frequencies different.

[0034] In some embodiments, the first-category second frequency band is higher than the third-category second frequency band, and the second-category second frequency band partially overlaps with the first-category second frequency band and the third-category second frequency band respectively.

[0035] In some other embodiments, the first-category second frequency band is higher than the third-category second frequency band, and there is no frequency band overlap among the first-category second frequency band, the second-category second frequency band, and the third-category second frequency band.

[0036] Please continue reading Figure 1 , at least two second antenna ports 130 include a third antenna port 131 and a fourth antenna port 132, the switching switch 140 includes a first switching switch 141 and a second switching switch 142, the first common end of the first switching switch 141 is connected to the radio frequency unit 101, the first selection end of the first switching switch 141 is connected to the third antenna port 131, the second selection end of the first switching switch 141 is connected to the third selection end of the second switching switch 142, the fourth selection end of the second switching switch 142 is connected to the ground end, and the second common end of the second switching switch 142 is connected to the fourth antenna port 132. The control unit 102 can control the switching of the first switching switch 141 and the second switching switch 142 so that the terminal antenna 100 is in a different second frequency band. Specifically, the first control end of the first switching switch 141 and the second control end of the second switching switch 142 are both connected to the control unit 102 to receive a control signal, and three connection modes can be obtained through the control unit 102:

[0037] 1. When the first switch 141 is switched to connect the first common terminal with the first selection terminal, and the second switch 142 is switched to connect the second common terminal with the fourth selection terminal, the third antenna port 131 is connected to the RF unit 101, and the fourth antenna port 132 is connected to the ground terminal. In this connection mode, the third antenna port 131 is in operation, and the fourth antenna port 132 is in grounding state, and is not connected to the RF unit 101;

[0038] 2. When the first switch 141 is switched to connect the first common terminal with the first selection terminal, and the second switch 142 is switched to connect the second common terminal with the third selection terminal, the third antenna port 131 is connected to the RF unit 101, and the fourth antenna port 132 is not connected to the RF unit 101 and the ground terminal. In this connection mode, the third antenna port 131 is in operation and the fourth antenna port 132 is in an empty state;

[0039] 3. When the first switching switch 141 is switched to connect the first common end with the second selection end, and the second switching switch 142 is switched to connect the second common end with the third selection end, the third antenna port 131 is not connected to the RF unit 101 and the ground, and the fourth antenna port 132 is connected to the RF unit 101. In this connection mode, the third antenna port 131 is in an empty state and the fourth antenna port 132 is in an operating state.

[0040] In some embodiments, at least one of the first switch 141 and the second switch 142 is a single-pole double-throw switch. Alternatively, the first switch 241 may be a single-pole triple-throw switch or a double-pole triple-throw switch.

[0041] In addition, the first switch 141 and the second switch 142 can both be connected to the RF unit 101 at the same time. Specifically, the first common end of the first switch 141 is connected to the RF unit 101, the first selection end of the first switch 141 is connected to the third antenna port 131, the second selection end of the first switch 141 is empty, the third selection end of the second switch 142 is connected to the RF unit 101, the fourth selection end of the second switch 142 is connected to the ground end, and the second common end of the second switch 142 is connected to the fourth antenna port 132.

[0042] It is understandable that the connection method of the third antenna port 131, the fourth antenna port 132, the first switch 141 and the second switch 142 is not specifically limited herein.

[0043] In the present application, the above-mentioned single terminal antenna is used to cover the low frequency of 700-960MHz, taking into account domestic and overseas needs, and the antenna is designed in a normalized manner to enhance product competitiveness. In particular, for compact 4G wireless devices, in the existing antenna technology, the internal space of the compact 4G wireless device cannot meet the requirements of using a single antenna to achieve full-frequency coverage of 700-960MHz, and the internal space of the compact 4G wireless device cannot be equipped with two antennas, so that the compact 4G wireless device, FDD low frequency mainly achieves frequency band coverage of 800-960MHz or 700-800MHz, and cannot take into account the 700-960Mhz low frequency full channel coverage. However, the present application can achieve 700-960Mhz low frequency full channel coverage through a single antenna, reducing the number of antennas, reducing costs, and greatly reducing the internal space requirements of the device, thereby enhancing market competitiveness.

[0044] See also Figure 2 , Figure 2 This is a schematic diagram of the framework of an embodiment of the terminal antenna frequency band control method of the present application. Specifically, it may include the following steps:

[0045] Step S210: comprising: determining a switch switching strategy based on the received frequency band requirement information.

[0046] In some embodiments, the terminal antenna 100 can be installed in a network device so that the network device can realize the networking function through the terminal antenna 100. Furthermore, in order to make the network state of the terminal stable, the network state of the terminal is predicted by the network prediction module. If the network state is predicted to be poor, the frequency band demand information is generated to switch the frequency band so that the network state of the terminal remains stable. After receiving the frequency band demand information, the terminal generates a corresponding switch switching strategy to switch the second frequency band in the terminal antenna 100. It can be understood that the terminal can be a mobile phone, a computer, or a tablet device, which is not specifically limited here.

[0047] In other embodiments, in order to ensure that the terminal has a good network environment in different regions, the control unit 102 may be used to obtain the location information of the terminal. Based on the location information, the frequency band requirement information is determined.

[0048] Step S220: Based on the switch switching strategy, control the switch in the terminal antenna to switch the connection mode of each second antenna port in the terminal antenna to switch to wireless communication in different second frequency bands.

[0049] Please refer to Figure 1 The terminal antenna 100 can determine the antenna low-frequency band requirement according to the spectrum resource information of different regions, that is, control the first switch 141 and the second switch 142 to switch accordingly according to the spectrum resources of each region. Specifically, the switch switching strategy is as follows:

[0050] 1. In response to the switch switching strategy, the first switch 141 is controlled to switch to a connection mode in which the first common terminal is connected to the first selection terminal, and the second switch 142 is switched to a connection mode in which the second common terminal is connected to the fourth selection terminal, the third antenna port 131 is connected to the radio frequency unit 101, and the fourth antenna port 132 is connected to the ground terminal, so as to switch to wireless communication of the first category and the second frequency band. Under the spatial coupling of the third antenna port 131, the first antenna port 120 is also in operation;

[0051] 2. In response to the switch switching strategy, the first switch 141 is controlled to switch to a connection mode in which the first common terminal is connected to the first selection terminal, and the second switch 142 is switched to a connection mode in which the second common terminal is connected to the third selection terminal, the third antenna port 131 is connected to the radio frequency unit 101, and the fourth antenna port 132 is not connected to the radio frequency unit 101 and the ground terminal, so as to switch to wireless communication of the second class and the second frequency band, and the first antenna port 120 is also in operation under the spatial coupling of the third antenna port 131;

[0052] 3. In response to the switch switching strategy, the first switch 141 is controlled to switch to a connection mode in which the first common end is connected to the second selection end, and the second switch 142 is switched to a connection mode in which the second common end is connected to the third selection end. The third antenna port 131 is not connected to the RF unit 101 and the ground end, and the fourth antenna port 132 is connected to the RF unit 101 to switch to wireless communication in the second frequency band of the third category. Under the spatial coupling of the fourth antenna port 132, the first antenna port 120 is also in operation.

[0053] Among them, the second frequency band of the first category, the second frequency band of the second category, and the second frequency band of the third category have at least some frequencies different.

[0054] In the above three modes, covering most areas means meeting the frequency coverage requirements of most regions, and the performance of the terminal antenna can be adjusted to optimize the frequency coverage range according to the actual environment. The three mode switching mainly corresponds to the spectrum resource definitions of different operators in different regions.

[0055] See also Figure 3 , Figure 3 This is a flow chart of another embodiment of the method for controlling the frequency band of a terminal antenna of the present application. Specifically, it may include the following steps:

[0056] Step S310: performing matching using the received frequency band requirement information to obtain a matching result.

[0057] In some embodiments, different switch switching strategies are pre-stored in the control unit 102, for example:

[0058] 10. Mode switch switching strategy: the first common end of the first switch 141 is switched to be connected to the first selection end, and the second common end of the second switch 142 is switched to be connected to the fourth selection end, the third antenna port 131 is connected to the RF unit 101, and the fourth antenna port 132 is connected to the ground end. In this connection mode, the antenna frequency band covers 800-960MHz & 1710-2690MHz;

[0059] 11. Mode switch switching strategy: the first common end of the first switch 141 is switched to be connected to the first selection end, and the second common end of the second switch 142 is switched to be connected to the third selection end, the third antenna port 131 is connected to the RF unit 101, and the fourth antenna port 132 is not connected to the RF unit 101 and the ground end. In this connection mode, the antenna frequency band covers 700-900MHz & 1710-2690MHz;

[0060] 0 1 mode switch switching strategy: the first common end of the first switching switch 141 is switched to be connected to the second selection end, and the second common end of the second switching switch 142 is switched to be connected to the third selection end, the third antenna port 131 is not connected to the RF unit 101 and the ground end, and the fourth antenna port 132 is connected to the RF unit 101. In this connection mode, the antenna frequency band covers 700-800MHz & 1710-2690MHz.

[0061] The frequency band requirement information is matched with the coverage frequency bands in the above three modes to obtain a matching result. Among them, the coverage frequency bands in the three modes must completely contain the frequency band requirement information for the matching to be successful.

[0062] It is understandable that, in addition to the above three types, the pre-stored switch switching strategies may also be other strategies, which are not specifically limited here.

[0063] Step S320: Determine a switch switching strategy based on the matching result.

[0064] In some embodiments, the mode that matches the frequency band requirement information can be obtained based on the matching result, and the mode is the switch switching strategy. Specifically, if the frequency band requirement information is 700-900MHz, and the matching result is that the frequency band requirement information successfully matches the 11-mode switch switching strategy, the 11-mode switch switching strategy is used as the switch switching strategy to be executed.

[0065] Step S330: Based on the switch switching strategy, control the switch in the terminal antenna to switch the connection mode of each second antenna port in the terminal antenna to switch to wireless communication in different second frequency bands.

[0066] This step is the same as the above step S220 and will not be described again here.

[0067] This application realizes the full frequency band of 700-960MHz with a single antenna by intelligently switching the antenna port of the terminal antenna. Compared with the dual antenna in the prior art, the number of antennas is reduced, the internal space requirement of the device is greatly reduced, the cost is reduced, and the market competitiveness is improved.

[0068] Those skilled in the art will appreciate that, in the above method of specific implementation, the order in which the steps are written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of the steps should be determined by their functions and possible internal logic.

The terminal antenna frequency band control device 400 includes an acquisition module 410 and a control module 420. The acquisition module 410 determines a switch switching strategy based on the received frequency band demand information.
