Antenna device and base station antenna system

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on December 29, 2023, with application number 202311867992.3 and application name “Antenna Device and Base Station Antenna System”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to an antenna device and a base station antenna system. Background Art

[0003] The development of 5G technology has placed greater demands on antennas. For example, antennas must be able to improve the capacity of existing Long Term Evolution (LTE) networks and evolve towards 5G New Radio (NR). For existing Multiple-Input Multiple-Output (MIMO) antennas, switching to a four-channel beam while maintaining the optimal splitting performance of an eight-channel beam requires the use of adapters. This adapter introduces losses, degrading existing network coverage, and increasing costs. Summary of the Invention

[0004] In view of this, the present application provides an antenna device and a base station antenna system, so as to more easily configure four of the six columns of dipole elements into a 4T4R link, while supporting soft splitting enhancement of the antenna device.

[0005] In a first aspect, an embodiment of the present application provides an antenna device, comprising: a first column of dipoles, a second column of dipoles, a third column of dipoles, a fourth column of dipoles, a fifth column of dipoles, and a sixth column of dipoles, arranged in sequence along a first direction. The distance between the first column of dipoles and the second column of dipoles is H1, the distance between the second column of dipoles and the third column of dipoles is H2, the distance between the fourth column of dipoles and the fifth column of dipoles is H3, and the distance between the fifth column of dipoles and the sixth column of dipoles is H4, where H1, H2, H3, and H4 are all within a first distance range. The distance between the third column of dipoles and the fourth column of dipoles is H5, where H5 is within a second distance range, where the minimum value in the second distance range is greater than the maximum value in the first distance range.

[0006] In the present application, a group of channel ports can be configured by the third column and the fourth column of oscillators, and another group of 4-channel ports can be configured by the first column and the sixth column of oscillators, so that two groups of 4-channel ports can be configured in one antenna device. The two groups of 4-channel ports are respectively connected to a corresponding radio frequency unit (RU) with four radio frequency channels, and two four-antenna transmitting and four-antenna receiving (Four Transmitter Four Receiver, 4T4R) transceiver links can be formed, that is, dual 4T4R links. Among them, there is a relatively large distance between the third column and the fourth column of oscillators, so that the third column and the fourth column of oscillators have relatively less interference, and a group of 4-channel ports can be configured by the third column and the fourth column of oscillators, and it is easier to configure the third column and the fourth column of oscillators with the required wavelength of the 4-channel port, such as 65° wavelength, so that the third column and the fourth column of oscillators radiate a better antenna pattern through the 4-channel port, reducing interference between cells.

[0007] In one possible implementation, the first column of oscillators includes two first ports, the sixth column of oscillators includes two additional first ports, and the four first ports are used to connect to the first RF unit to configure a first transceiver link. The first RF unit includes four first channels, and the four first ports are signal-connected to the four first channels in a one-to-one correspondence; and / or the third column of oscillators includes two second ports, the fourth column of oscillators includes two additional second ports, and the four second ports are signal-connected to the second RF unit to configure a second transceiver link. The second RF unit includes four second channels, and the four second ports are signal-connected to the four second channels in a one-to-one correspondence. A 4T4R link can be formed between the four first ports and the four first channels, and another 4T4R link can be formed between the four second ports and the four second channels. These two 4T4R links can be configured selectively or simultaneously to form a dual 4T4R link.

[0008] In one possible implementation, at least some of the first, second, third, fourth, fifth, and sixth columns of oscillators are connected to a radio frequency unit to configure a third transceiver link to support split beam formation. This third transceiver link supports LTE scenarios, achieves good splitting characteristics, ensures orthogonality of baseband weights in different directions, and thus ensures good antenna performance.

[0009] In one possible implementation, the third transceiver link includes a first link, and the second column of oscillators, the third column of oscillators, the fourth column of oscillators, and the fifth column of oscillators each include two third ports. The third ports of the second column of oscillators, the third column of oscillators, the fourth column of oscillators, and the fifth column of oscillators are used to connect to a third radio frequency unit to configure the first link. The third radio frequency unit includes eight third channels, and the eight third ports are signal-connected to the eight third channels of the second column of oscillators, the third column of oscillators, the fourth column of oscillators, and the fifth column of oscillators in a one-to-one correspondence. Thus, an eight-antenna transmit and eight-antenna receive (8T8R) transceiver link, i.e., an 8T8R link, can be formed. The 8T8R link can achieve good soft-splitting characteristics in LTE scenarios. At the same time, the average spacing of the four columns of oscillators is slightly greater than 0.5 wavelengths, so that the antenna beam has almost no grating lobes, which can support the smooth evolution of 5G NR.

[0010] In a possible implementation, the operating frequency band corresponding to the first link is different from the operating frequency band corresponding to the first transceiver link; and / or the operating frequency band corresponding to the first link is different from the operating frequency band corresponding to the second transceiver link.

[0011] In one possible implementation, the four first ports of the first column of oscillators and the sixth column of oscillators are signal-connected in a one-to-one correspondence with the four first channels of the four first RF units, so that the first transceiver link can be configured as a 4T4R link. The third transceiver link includes a second link, and the second column of oscillators, the third column of oscillators, the fourth column of oscillators, and the fifth column of oscillators each include two fourth ports, and the fourth ports of the second column of oscillators, the third column of oscillators, the fourth column of oscillators, and the fifth column of oscillators are used to connect to a fourth RF unit to configure the second link. The fourth RF unit includes eight fourth channels, and the eight fourth ports are signal-connected in a one-to-one correspondence with the eight fourth channels of the second column of oscillators, the third column of oscillators, the fourth column of oscillators, and the fifth column of oscillators, i.e., the second link can be configured as an 8T8R link. The operating frequency band corresponding to the second link is the same as the operating frequency band corresponding to the first transceiver link. Among them, the above-mentioned 4T4R link and 8T8R link can be configured at the same time. The working frequency band corresponding to the second link is the same as the working frequency band corresponding to the first transceiver link, that is, the 4T4R link and the 8T8R link are equivalent to a 12T12R link. The 12T12R link can be connected to the same radio frequency unit. This connection method enables the six columns of oscillators to be jointly shaped, thereby constructing a three-split beam, which can increase LTE capacity by 30% to 40%, and can support the evolution of LTE and 5G NR.

[0012] In one possible implementation, the antenna apparatus further includes a power splitting network, wherein at least some of the first, second, third, fourth, fifth, and sixth columns of oscillators are connected to an input of the power splitting network, and an output of the power splitting network is connected to a radio frequency unit. The power splitting network can combine multiple signal energies from at least some of the six columns of oscillators into one output, thereby facilitating configuration to support LTE scenarios and achieve excellent soft-splitting performance.

[0013] In one possible implementation, the power splitting network includes a first power splitter and a second power splitter. The first column of oscillators and the third column of oscillators are combined through the first power splitter to output a first RF signal. The power ratio output by the first power splitter is 1:1. The difference in feeder length between the first column of oscillators and the third column of oscillators is 1 / 2λ, where λ is the wavelength corresponding to the center frequency of the operating frequency band of the antenna device. The fourth column of oscillators and the sixth column of oscillators are combined through the second power splitter to output a second RF signal. The power ratio output by the second power splitter is 1:1. The difference in feeder length between the fourth column of oscillators and the sixth column of oscillators is 1 / 2λ, where λ is the wavelength corresponding to the center frequency of the operating frequency band of the antenna device. The third transceiver link includes a third link; the first power splitter, the second power splitter, the second column of oscillators, and the fifth column of oscillators are all connected to a fifth RF unit to configure the third link. Among them, through the first power divider and the second power divider, the six columns of oscillators can output four RF signals, so that the antenna device is configured as a software-defined antenna (SDA) and can be configured as four-channel six-sector (4T6S), which can achieve capacity expansion of the LTE network and increase the capacity by nearly 20%. At the same time, the distance between the first column of oscillators 1 and the third column of oscillators 3, as well as the distance between the fourth column of oscillators 4 and the sixth column of oscillators 6 are both small, which will not lead to the generation of grating lobes, can support the smooth evolution of 5G NR, and can help operators save fixed investment and operating expenses.

[0014] In one possible implementation, the functional network includes a third power splitter, a fourth power splitter, and a fifth power splitter. The first column of oscillators and the fourth column of oscillators are combined through the third power splitter to output a fifth RF signal. The power ratio of the output of the third power splitter is x:1, where x is 0.1, 0.2, 0.3, 0.4, or 0.5. The second column of oscillators and the fifth column of oscillators are combined through the fourth power splitter to output a sixth RF signal. The power ratio of the output of the fourth power splitter is 1:1. The third column of oscillators and the sixth column of oscillators are combined through the fifth power splitter to output a seventh RF signal. The power ratio of the output of the fifth power splitter is 1:y, where y is 0.1, 0.2, 0.3, 0.4, or 0.5. The third transceiver link includes a fourth link; the third power splitter, the fourth power splitter, and the fifth power splitter are all connected to the sixth RF unit to configure the fourth link. Among them, the third power divider, the fourth power divider and the fifth power divider can all be connected to the sixth radio frequency unit to configure the above-mentioned fourth link, so that the antenna device is configured as an SDA antenna, and can be configured as two channels and nine sectors (Two Transmitter For Nine Sectors, 2T9S), which can achieve further expansion of the LTE network and can realize about 2.0 times the capacity of LTE.

[0015] In one possible implementation, the fifth RF signal includes three first RF signals with different phases, the three first RF signals covering three split first sectors, and each first RF signal covering a corresponding first sector. The sixth RF signal includes three second RF signals with different phases, the three second RF signals covering three split second sectors, and each second RF signal covering a corresponding second sector. The seventh RF signal includes three third RF signals with different phases, the three third RF signals covering three split third sectors, and each third RF signal covering a corresponding third sector. As described above, each antenna unit in each element column can be a dual-polarized antenna unit, so that each element column can have two output ports. In this embodiment, the fifth RF signal, the sixth RF signal, and the seventh RF signal are each output from the corresponding two output ports. That is, the antenna device can be configured with a total of six antenna output ports, and these six antenna output ports can be respectively connected to the six RF channels of the sixth RF unit.

[0016] In one possible implementation, the antenna device further includes a resonance unit, which is coupled to the resonance gaps of at least some columns of the first column of elements, the third column of elements, the fourth column of elements, and the sixth column of elements, and is used to narrow the wavelength of the first column of elements, the third column of elements, the fourth column of elements, or the sixth column of elements to between 55° and 75°, thereby facilitating the configuration of a 4T4R link or a 2T2R link.

[0017] In one possible implementation, the resonance unit includes a plurality of resonance elements, which are arranged in an array, and the maximum length of the resonance element is less than or equal to 0.25λ, where λ is the wavelength corresponding to the center frequency of the vibrator adjacent to the resonance unit.

[0018] In one possible implementation, H1, H2, H3, and H4 are all greater than or equal to 0.45λ and less than or equal to 0.55λ, where λ is the wavelength corresponding to the center frequency of the operating frequency band of the antenna assembly. By ensuring that H1, H2, H3, and H4 are within the above wavelength range, good soft-splitting characteristics are achieved for the LTE network.

[0019] In one possible implementation, H5 is greater than or equal to 0.6λ and less than or equal to 0.8λ, where λ is the wavelength corresponding to the center frequency of the operating frequency band of the antenna device. Setting H5 within the above wavelength range facilitates configuration of a 4T4R link.

[0020] In one possible implementation, H1, H2, H3, and H4 are all greater than or equal to 70 mm and less than or equal to 85 mm, and H5 is greater than or equal to 93 mm and less than or equal to 124 mm. Ensuring that H1, H2, H3, H4, and H5 are within the corresponding physical distance ranges above facilitates achieving good soft-split characteristics for the LTE network and facilitating configuration of 4T4R links.

[0021] In a possible implementation, the resonance points of the first column of vibrators and the sixth column of vibrators are located in a frequency band of 1425 MHz to 2690 MHz. The resonance points of the third column of vibrators and the fourth column of vibrators are located in a frequency band of 1710 MHz to 2690 MHz.

[0022] In one possible implementation, H1, H2, H3, and H4 are all greater than or equal to 162 mm and less than or equal to 198 mm, and H5 is greater than or equal to 216 mm and less than or equal to 288 mm. Ensuring that H1, H2, H3, H4, and H5 are within the corresponding physical distance ranges above facilitates achieving good soft-split characteristics for the LTE network and facilitating configuration of 4T4R links.

[0023] In a possible implementation, the resonance points of the first column of oscillators and the sixth column of oscillators are located in a frequency band of 617 MHz to 960 MHz;

[0024] The resonance points of the third column of vibrators and the fourth column of vibrators are located in a frequency band of 690 MHz to 960 MHz.

[0025] In a second aspect, the present application further provides a base station antenna system, characterized by comprising a radio frequency unit and the antenna device provided in the first aspect of the present application, wherein the oscillator in the antenna device is connected to the radio frequency unit to receive or transmit radio frequency signals. The base station antenna system including the antenna device provided in the first aspect of the present application has similar technical effects as the aforementioned antenna device and is not further described here.

DETAILED DESCRIPTION

[0046] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0047] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0048] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0049] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0050] In the description of this application, unless otherwise specified or limited, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0051] With the development of 5G technology, more demands have been made on antennas. For example, antennas need to be able to improve the capacity of the Long Term Evolution (LTE) technology of the existing network and also be able to evolve towards the 5G New Radio (NR). For example, for existing Multiple-input Multiple-output (MIMO) antennas, when meeting the better splitting performance of forming 8-channel beams, the existing antennas will evolve to form 4-channel beams, which is not optimal and the beam width will be widened, thereby increasing interference between cells and being difficult to be accepted by operators. For example, for an antenna device composed of six columns of dipoles, in order to meet the better splitting performance of forming 8-channel beams, the spacing between two adjacent dipoles in the middle four columns needs to meet 0.5λ, where λ is the free space wavelength. However, the dipoles corresponding to the 0.5λ spacing have a wavelength of approximately 90°. If the middle four columns of dipoles are configured to form a 4-channel beam, an adapter needs to be introduced to narrow the approximately 90° wavelength to a wavelength of approximately 65°. However, using an adapter would introduce losses, deteriorating existing network coverage and increasing costs, making it difficult for operators to accept. Without an adapter, the transducer would have a beamwidth of approximately 90°, increasing inter-cell interference and deteriorating key KPIs like call drop rate and handover failure rate, also difficult for operators to accept.

[0052] In addition, for existing antennas with multiple columns of elements, in order to improve baseband soft-splitting performance in LTE scenarios, it is usually necessary to configure baseband splitting weights for some elements. Specifically, horizontal baseband weights can be configured for the antenna array. The horizontal baseband weights can be understood as performing amplitude and phase transformation on the baseband signal and mapping the baseband signal to the RF channel. It should be noted that configuring horizontal baseband weights for the antenna array means configuring horizontal baseband weights for each antenna element in the array. The horizontal baseband weights of the antenna array include the horizontal baseband weights corresponding to each antenna element. The horizontal baseband weights of the antenna array are used to determine the horizontal beam properties of the beam. The horizontal beam properties of the beam primarily include the horizontal direction and shape of the beam. In other words, the shape and horizontal direction of the beam can be determined based on the arrangement of the antenna elements and their corresponding horizontal baseband weights. Similarly, the antenna array can also be configured with baseband weights in the vertical direction. It can be understood that each antenna unit should have a corresponding baseband weight in the vertical direction. The baseband weights in the vertical direction of the antenna array include the baseband weights in the vertical direction of each antenna unit. The baseband weights in the vertical direction of the antenna array are used to determine the vertical beam properties of the beam. The baseband weights in the vertical direction can be understood as the mapping of the baseband signal to the RF channel. The vertical beam properties corresponding to the beam mainly include the direction and shape of the beam in the vertical direction. In other words, the shape of the beam in the vertical direction and the direction of the beam in the vertical direction can be determined based on the arrangement of the antenna units and the baseband weights in the vertical direction. In the above manner, the vertical beam properties corresponding to the beam can be determined by setting the baseband weights in the vertical direction of the antenna units, thereby improving the flexibility of beam adjustment.

[0053] For example, FIG4 is a schematic diagram of configuring baseband weights through four columns of oscillators in an antenna device. Referring to FIG4 , for the four columns of oscillators arranged in sequence in the first direction X (from left to right, the first oscillator 14, the second oscillator 15, the third oscillator 16, and the fourth oscillator 17), the first oscillator 14 and the second oscillator 15 can be configured with baseband weights in one direction, and the third oscillator 16 and the fourth oscillator 17 can be configured with baseband weights in another direction. However, this configuration will result in poor splitting performance. FIG5 is a directional diagram of the antenna device shown in FIG4 . Referring to FIG5 , the connection method of the antenna device shown in FIG4 can radiate in two directions, and there is a large area of ​​overlap between the areas radiating in the two directions, which will cause the radiation of the antenna device in the two areas to have greater interference.

[0054] The embodiment of the present application provides an antenna device, which can be applied to a base station antenna system for receiving or transmitting electromagnetic waves. It should be understood that the antenna device and base station antenna system provided in the embodiment of the present application can be applied to a variety of communication systems, such as: global system of mobile communication (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) system, general packet radio service (GPRS), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, universal mobile telecommunication system (UMTS), world-wide interoperability for microwave access (WiMAX) communication system or fifth generation mobile communication technology (5th-generation, 5G), etc. It should be noted that the embodiment of the present application is not limited to a specific communication system.

[0055] Figure 1 is a schematic diagram of an antenna device provided in an embodiment of the present application. Referring to Figure 1 , the antenna device provided in the present application includes a first column of oscillators 1, a second column of oscillators 2, a third column of oscillators 3, a fourth column of oscillators 4, a fifth column of oscillators 5, and a sixth column of oscillators 6, arranged in sequence along a first direction X. In one possible implementation, the first direction X can be a single straight line. Each column of oscillators can include multiple antenna units, each of which can independently receive or transmit electromagnetic waves. In one possible implementation, the antenna units in each column of oscillators can be arrayed in a second direction Y, which is perpendicular to the first direction X.

[0056] FIG2 is a topological diagram of an antenna device provided in an embodiment of the present application. Referring to FIG2 , the distance between the first column of oscillators 1 and the second column of oscillators 2 is H1, the distance between the second column of oscillators 2 and the third column of oscillators 3 is H2, the distance between the fourth column of oscillators 4 and the fifth column of oscillators 5 is H3, and the distance between the fifth column of oscillators 5 and the sixth column of oscillators 6 is H4. H1, H2, H3, and H4 are all within a first distance range. The distance between the third column of oscillators 3 and the fourth column of oscillators 4 is H5, and H5 is within a second distance range. The first distance range and the second distance range both have a maximum value and a minimum value, and the minimum value in the second distance range is greater than the maximum value in the first distance range.

[0057] Figure 3 is a schematic diagram of a configuration of an antenna device provided in an embodiment of the present application. Referring to Figure 3, the distance H5 between the third column of dipoles 3 and the fourth column of dipoles 4 is greater than H1, H2, H3, and H4, so that relatively less interference is generated between the third column of dipoles 3 and the fourth column of dipoles 4. A group of 4-channel ports can be configured through the third column of dipoles 3 and the fourth column of dipoles 4, and it is easier to configure the third column of dipoles 3 and the fourth column of dipoles 4 with the required beamwidth of the 4-channel ports, for example, a 65° beamwidth, so that the third column of dipoles 3 and the fourth column of dipoles 4 radiate a better antenna pattern through the 4-channel ports, thereby reducing interference between cells.

[0058] Furthermore, the other four columns of transducers located between the first column of transducers 1 and the sixth column of transducers 6 all have adjacent transducers on both sides. This causes the other transducers located between the first column of transducers 1 and the sixth column of transducers 6 to be subject to coupling interference from the adjacent transducers on both sides, making it difficult to configure a 4-channel port. In this embodiment, referring to FIG3 , the first column of transducers 1 and the sixth column of transducers 6 are located at the extreme edges, and the first column of transducers 1 and the sixth column of transducers 6 have adjacent transducers on only one side. That is, the first column of transducers 1 couples with the adjacent transducers only on the side facing the sixth column of transducers 6, and the sixth column of transducers 6 couples with the adjacent transducers only on the side facing the first column of transducers 1. This results in relatively little interference to the first column of transducers 1 and the sixth column of transducers 6, and a relatively narrow bandwidth, making it easier to configure the required bandwidth of a 4-channel port, such as a 65° bandwidth.

[0059] 3 , a group of 4-channel ports can be configured through the third column of oscillators 3 and the fourth column of oscillators 4, and another group of 4-channel ports can be configured through the first column of oscillators 1 and the sixth column of oscillators 6. Thus, two groups of 4-channel ports can be configured in one antenna device. The two groups of 4-channel ports are respectively connected to a corresponding radio frequency unit (RU) having four radio frequency channels, forming two four-antenna transmitting and four-antenna receiving (4T4R) transceiver links, i.e., dual 4T4R links. The radio frequency unit can be a remote radio unit (RRU). In one possible implementation, the two 4T4R links can respectively support different frequency bands. For example, for the intermediate frequency, the 4T4R link configured by the first column of oscillators 1 and the sixth column of oscillators 6 can support a frequency band of 1425MHz to 2690MHz, and the 4T4R link configured by the third column of oscillators 3 and the fourth column of oscillators 4 can support a frequency band of 1710MHz to 2690MHz. For low frequency, the 4T4R link configured by the first column of oscillators 1 and the sixth column of oscillators 6 can support a frequency band of 617MHz to 960MHz, and the 4T4R link configured by the third column of oscillators 3 and the fourth column of oscillators 4 can support a frequency band of 690MHz to 960MHz. That is to say, compared with the third column of oscillators 3 and the fourth column of oscillators 4 in the middle, the first column of oscillators 1 and the sixth column of oscillators 6 support a wider bandwidth. In a possible implementation, the two 4T4R links can also support the same frequency band. For example, for medium frequency, the two 4T4R links can both support a frequency band of 1710MHz to 2690MHz. For low frequency, the two 4T4R links can both support a frequency band of 690MHz to 960MHz. That is to say, the first column of oscillators 1 and the sixth column of oscillators 6 located at the edge support the same bandwidth as the third column of oscillators 3 and the fourth column of oscillators 4 located in the middle.

[0060] In one possible implementation, within the frequency band range of 1425MHz to 2690MHz, for the 4T4R RRU corresponding to the 4T4R link, any communication frequency band within the frequency band range of 1425MHz to 2690MHz can be supported, such as 1.4G, 1.8G (B3 band), 2.1G (B1 band), 2.3G (B40 band) or 2.6G (B7 band or B38 band), etc. In addition, the 4T4R RRU can also support a combination of any communication frequency bands within the frequency band range of 1425MHz to 2690MHz, such as 1.8 / 2.1G, 2.3 / 2.6G, 1.8 / 2.1 / 2.6G, etc. In one possible implementation, within the frequency band range of 1710MHz to 2690MHz, for the 4T4R RRU corresponding to the 4T4R link, any communication frequency band within the frequency band range of 1710MHz to 2690MHz can be supported, such as 1.8G (B3 band), 2.1G (B1 band), 2.3G (B40 band) or 2.6G (B7 band or B38 band), as well as other operator frequency bands within the above frequency band range, such as 2.0G. In addition, the 4T4R RRU can also support a combination of any several communication frequency bands within the frequency band range of 1710MHz to 2690MHz, such as 1.8 / 2.1G, 2.3 / 2.6G, 1.8 / 2.1 / 2.6G, etc.

[0061] In one possible implementation, a 4T4R link can be configured, that is, a 4T4R link can be configured by the third column of oscillators 3 and the fourth column of oscillators 4, or a 4T4R link can be configured by the first column of oscillators 1 and the sixth column of oscillators 6. In another embodiment, a dual 4T4R link can also be configured. In some other embodiments, since the wavelength of the first column of oscillators 1, the third column of oscillators 3, the fourth column of oscillators 4 or the sixth column of oscillators 6 meets 55° to 75°, any one of the first column of oscillators 1, the third column of oscillators 3, the fourth column of oscillators 4 or the sixth column of oscillators 6 can be configured as a two-antenna transmitting and two-antenna receiving (Two Transmitter Two Receiver, 2T2R) transceiver link. For example, a 4T4R link can be reduced to one or two 2T2R links.

[0062] In one possible implementation, H1, H2, H3, and H4 can all be greater than or equal to 0.45λ and less than or equal to 0.55λ, where λ is the wavelength corresponding to the center frequency of the operating frequency band of the antenna device. H1, H2, H3, and H4 can be the same or different. For example, H1, H2, H3, and H4 can be 0.45λ, 0.5λ, 0.55λ, and so on. In one possible implementation, H5 can be greater than or equal to 0.6λ and less than or equal to 0.8λ. For example, H5 can be 0.6λ, 0.7λ, 0.8λ, and so on. λ is the wavelength corresponding to the center frequency of the operating frequency band of the antenna device. By ensuring that H1, H2, H3, H4, and H5 meet the above-mentioned corresponding wavelength ranges, it is possible to configure a dual 4T4R link without using an adapter while taking into account the overall size of the antenna device, thereby achieving a miniaturized antenna design.

[0063] In one possible implementation, for the intermediate frequency, the resonance points corresponding to the first column of vibrators 1 and the sixth column of vibrators 6 can be located in the frequency band of 1425MHz to 2690MHz. The resonance points corresponding to the third column of vibrators 3 and the fourth column of vibrators 4 can be located in the frequency band of 1710MHz to 2690MHz. In order to take into account the soft splitting performance of the LTE network, the operating frequency band of the antenna device can specifically be a frequency division duplexing (FDD) band, and the core frequency range of FDD is 1710MHz to 2170MHz, with a center frequency of 1940MHz. Thus, the physical distances corresponding to H1, H2, H3, and H4 within the range of 0.45λ to 0.55λ can all be greater than or equal to 70 mm and less than or equal to 85 mm. For example, the physical distances corresponding to H1, H2, H3, and H4 can be 70 mm, 77 mm, 80 mm, 85 mm, etc. The physical distance corresponding to H5 within the range of 0.6λ to 0.8λ can be greater than or equal to 93 mm and less than or equal to 124 mm. For example, the physical distance corresponding to H5 can be 93 mm, 100 mm, 110 mm, 124 mm, etc. In other embodiments, the antenna device can also use the frequency band of 2500 MHz to 2690 MHz, which is not limited in this embodiment.

[0064] In one possible implementation, for low frequencies, the resonance points corresponding to the first column of oscillators 1 and the sixth column of oscillators 6 can be located within the frequency band of 617 MHz to 960 MHz. The resonance points corresponding to the third column of oscillators 3 and the fourth column of oscillators 4 can be located within the frequency band of 690 MHz to 960 MHz. To ensure soft-splitting performance of the LTE network, the operating frequency band of the antenna device can specifically be an FDD band. The frequency range of FDD low-band LTE and NR is 703 MHz to 960 MHz, with a center frequency of 831.5 MHz. Thus, the physical distances corresponding to H1, H2, H3, and H4 in the range of 0.45λ to 0.55λ can all be greater than or equal to 162mm and less than or equal to 198mm. For example, the physical distances corresponding to H1, H2, H3, and H4 can be 162mm, 170mm, 180mm, 198mm, etc. The physical distance corresponding to H5 in the range of 0.6λ to 0.8λ can be greater than or equal to 216mm and less than or equal to 288mm. For example, the physical distance corresponding to H5 can be 216mm, 230mm, 255mm, 288mm, etc. Thus, the present application can realize the deployment of low-frequency antennas and medium-frequency antennas through a single antenna device.

[0065] As described above, using two of the four columns of oscillators to configure baseband weights in one direction will result in poor splitting performance. Figure 6 is a schematic diagram of the antenna device provided in an embodiment of the present application with a second configuration. Referring to Figure 6, in this embodiment, at least some of the columns of oscillators in the first column 1, the second column 2, the third column 3, the fourth column 4, the fifth column 5, and the sixth column 6 can be configured with baseband weights in different directions. For example, the first column 1, the second column 2, and the third column 3 can be configured with baseband weights in one direction, and the fourth column 4, the fifth column 5, and the sixth column 6 can be configured with baseband weights in another direction. This connection method can achieve good splitting performance. Figure 7 is a directional diagram of the antenna device shown in Figure 6. Referring to Figure 7, the connection method of the antenna device shown in Figure 6 can radiate in two directions, and there is a small area of ​​overlap between the areas radiating in the two directions, thereby reducing interference between the two areas and significantly improving the capacity of the LTE scenario by 10% to 20%.

[0066] For the antenna device provided in this application, by making the distance between the third column of oscillators 3 and the fourth column of oscillators 4 relatively larger, the third column of oscillators 3 and the fourth column of oscillators 4 can be configured as a 4T4R link without the need for an adapter. Since the adapter will cause a loss of 0.5 to 1 dB, in this embodiment, the loss caused by the adapter can be avoided, thereby reducing the coverage by 0.5 to 1 dB. At the same time, the antenna device provided in this application only requires one hardware deployment to achieve hardware adaptation of the RRU, such as dual 4T4R, 8T8R, 12T12R, etc., and can achieve the long-term evolution of LTE and 5G NR without the need to replace the antenna, which can help operators save fixed investment and operating costs. In one possible implementation, the directional pattern shown in Figure 8 corresponds to an antenna device in which H1, H2, H3 and H4 are all 77m and H5 is 100mm. Referring to Figure 8, the LTE network corresponding to the directional pattern shown in Figure 8 can obtain a larger capacity.

[0067] In one possible implementation, the antenna units in each column of oscillators are all dual-polarized antenna units, that is, each column of oscillators can have two ports. In this embodiment, the technical solution of this embodiment is described in detail by taking the +45° and -45° orthogonal dual-polarized antenna units as an example, but this embodiment is not limited thereto. For example, the antenna units can be 0° and 90° orthogonal dual-polarized antenna units. In one embodiment, the first column of oscillators 1 includes two first ports, and the sixth column of oscillators 6 includes another two first ports, that is, the first column of oscillators 1 and the sixth column of oscillators 6 include a total of four first ports, and the four first ports are used to connect to the first radio frequency unit 7 to configure a first transceiver link. Among them, the first radio frequency unit 7 includes four first channels, and the four first ports are signal-connected to the four first channels in a one-to-one correspondence, so that the first transceiver link can be configured as a 4T4R link. In one possible implementation, the third column of oscillators 3 includes two second ports, and the fourth column of oscillators 4 includes another two second ports. That is, the third and fourth columns of oscillators 3 and 4 include a total of four second ports, which are used to connect to the second RF unit 8 to configure a second transceiver link. The second RF unit 8 includes four second channels, and the four second ports are signal-connected to the four second channels in a one-to-one correspondence, thereby configuring the second transceiver link as another 4T4R link. In one possible implementation, the two 4T4R links can be configured selectively, or they can be configured simultaneously to form a dual 4T4R link.

[0068] As described above, the first column of vibrators 1, the third column of vibrators 3, the fourth column of vibrators 4 and the sixth column of vibrators 6 can all be used to configure a 4T4R link. The configuration of the 4T4R link requires that the wavelength of the corresponding vibrators needs to be between 55° and 75°. To this end, in a possible implementation method, Figure 9 is a schematic diagram of another antenna device provided in an embodiment of the present application. Referring to Figure 9, the antenna device also includes a resonance unit 13. The resonance unit 13 can be arranged near at least some of the columns of vibrators in the first column of vibrators 1, the third column of vibrators 3, the fourth column of vibrators 4 and the sixth column of vibrators 6. The resonance unit 13 can be gap-coupled and connected with the first column of vibrators 1, the third column of vibrators 3, the fourth column of vibrators 4 and the sixth column of vibrators 6. Therefore, on the basis that H5 is greater than H1, H2, H3 and H4, the resonance unit 13 can narrow the wavelength of the first column of vibrators 1, the third column of vibrators 3, the fourth column of vibrators 4 or the sixth column of vibrators 6 to between 55° and 75°. For example, the wavelength of the corresponding vibrator can be narrowed to about 65°, which is conducive to configuring a 4T4R link or a 2T2R link.

[0069] FIG10 is a schematic diagram of another antenna device provided in an embodiment of the present application. Referring to FIG10 , in one possible implementation, the resonant unit 13 includes a plurality of resonant elements 131 arranged in an array. The shape of the resonant element 131 may be square, rectangular, etc. The maximum length dimension of the resonant element 131 is less than or equal to 0.25λ, where λ is the wavelength corresponding to the center frequency of the oscillator adjacent to the resonant unit 13. For example, FIG11 is a front view of a resonant unit 13 provided in an embodiment of the present application. Referring to FIG11 , the resonant unit 13 may be composed of 16 resonant elements 131 arranged in a 4×4 rectangular array. In other embodiments, the resonant unit 13 may also be composed of another number of resonant elements 131 arranged in an array, which is not limited in this embodiment. The resonant unit 13 may be arranged near the corresponding column of oscillators, and one resonant unit 13 may be provided near the oscillator, or multiple resonant units 13 may be provided. The specific number and position of the resonant units 13 may be determined based on the effect of narrowing the oscillator's wave width.

[0070] In one possible implementation, as described above, at least some of the first column of elements 1, the second column of elements 2, the third column of elements 3, the fourth column of elements 4, the fifth column of elements 5, and the sixth column of elements 6 are connected to the radio frequency unit to configure a third transceiver link, which can be used to support split beam formation. This third transceiver link is used to support LTE scenarios, achieve good splitting characteristics, ensure orthogonality of baseband weights in different directions, and thus ensure good antenna performance.

[0071] Figure 12 is a schematic diagram of another antenna device provided in an embodiment of the present application. Referring to Figure 12, in a possible implementation, the third transceiver link may include the first link. As described above, the antenna units in each column of oscillators may be dual-polarized antenna units, so that each column of oscillators has two ports. In a possible implementation, the second column of oscillators 2, the third column of oscillators 3, the fourth column of oscillators 4 and the fifth column of oscillators 5 each include two third ports, that is, the second column of oscillators 2, the third column of oscillators 3, the fourth column of oscillators 4 and the fifth column of oscillators 5 include a total of eight third ports, and the eight third ports are used to connect to the third radio frequency unit 9 to configure the above-mentioned first link. Among them, the third radio frequency unit 9 includes eight third channels, and the eight third ports are signal-connected to the eight third channels in a one-to-one correspondence, thereby forming an eight-antenna transmitting and eight-antenna receiving (Eight Transmitter Eight Receiver, 8T8R) transceiver link, that is, an 8T8R link. Figure 13 is the directional diagram of the antenna device shown in Figure 12. Referring to Figure 13, the 8T8R link can obtain good soft splitting characteristics in the LTE scenario. At the same time, the average spacing between the four columns of oscillators is slightly larger than 0.5 times the wavelength, thereby suppressing the grating lobes of the antenna beam and supporting the smooth evolution of 5G NR.

[0072] In a possible implementation, the first link and the first transceiver link can be configured selectively, or the first link and the second transceiver link can be configured selectively. For example, the 8T8R link and the 4T4R link can be configured selectively according to the application scenario. The working frequency band corresponding to the first link is different from the working frequency band corresponding to the first transceiver link; or the working frequency band corresponding to the first link is different from the working frequency band corresponding to the second transceiver link; or the working frequency band corresponding to the first link is different from the working frequency bands corresponding to the first transceiver link and the second transceiver link. For example, for the medium frequency band, the first transceiver link and / or the second transceiver link can support the frequency band of 1425MHz to 2690MHz, and the first link can support the frequency band of 1710MHz to 2690MHz. For example, for the low frequency band, the first transceiver link and / or the second transceiver link can support the frequency band of 617MHz to 960MHz, and the first link can support the frequency band of 690MHz to 960MHz.

[0073] FIG14 is a schematic diagram of another antenna device provided by an embodiment of the present application. Referring to FIG14 , in a possible implementation, as described above, the first column of oscillators 1 and the sixth column of oscillators 6 include a total of four first ports, and the four first ports are signal-connected to the four first channels of the four first RF units in a one-to-one correspondence, so that the first transceiver link can be configured as a 4T4R link. The third transceiver link includes a second link, and the second column of oscillators 2, the third column of oscillators 3, the fourth column of oscillators 4, and the fifth column of oscillators 5 each include two fourth ports, that is, the second column of oscillators 2, the third column of oscillators 3, the fourth column of oscillators 4, and the fifth column of oscillators 5 include a total of eight fourth ports, and the eight fourth ports are used to connect to the fourth RF unit 10. The fourth RF unit 10 includes eight fourth channels, and the eight fourth ports are signal-connected to the eight fourth channels in a one-to-one correspondence, that is, the second link can be configured as an 8T8R link. Among them, the above-mentioned 4T4R link and 8T8R link can be configured at the same time. The working frequency band corresponding to the second link is the same as the working frequency band corresponding to the first transceiver link, that is, the 4T4R link and the 8T8R link are collectively equivalent to a 12T12R link. The 12T12R link can be connected to the same RF unit. This connection method enables the six columns of oscillators to be jointly shaped, thereby constructing a three-split beam (refer to Figure 15), which can increase the LTE capacity by 30% to 40%, and can support the evolution of LTE and 5G NR.

[0074] In one possible implementation, the antenna device further includes a power division network, wherein at least some of the first column of oscillators 1, the second column of oscillators 2, the third column of oscillators 3, the fourth column of oscillators 4, the fifth column of oscillators 5, and the sixth column of oscillators 6 are connected to the input end of the power division network, and the output end of the power division network is used to connect to the radio frequency unit. The power division network may include a power divider, an adapter, a combiner, etc., which can divide one input signal energy into two or more equal or unequal signal energies, or can also combine multiple signal energies into one output. In this embodiment, the power division network can combine the multiple signal energies of at least some of the six columns of oscillators into one output, so as to facilitate configuration to support LTE scenarios and obtain excellent soft splitting performance.

[0075] Figure 16 is a schematic diagram of another antenna device provided in an embodiment of the present application. Referring to Figure 16, in a possible implementation, the third transceiver link includes a third link. The power division network 18 may include a first power divider and a second power divider. The first column of vibrators 1 and the third column of vibrators 3 are combined through the first power divider to output a first RF signal. The fourth column of vibrators 4 and the sixth column of vibrators 6 are combined through the second power divider to output a second RF signal. The second column of vibrators 2 can output a third RF signal, and the fifth column of vibrators 5 can output a fourth RF signal. Among them, the power ratio output by the first power divider is 1:1, the difference in feeder length between the first column of vibrators 1 and the third column of vibrators 3 is 1 / 2λ, and λ is the wavelength corresponding to the center frequency of the working frequency band of the antenna device, so that the phase angle difference between the first column of vibrators 1 and the third column of vibrators 3 is approximately within an angle range of about 180°. The power ratio output by the second power divider is 1:1, and the difference in feeder length between the fourth column of elements 4 and the sixth column of elements 6 is 1 / 2λ, where λ is the wavelength corresponding to the center frequency of the antenna device's operating frequency band. This ensures that the phase angle difference between the fourth column of elements 4 and the sixth column of elements 6 is approximately within an angular range of 180°. The first power divider, the second power divider, the second column of elements 2, and the fifth column of elements 5 can all be connected to the fifth RF unit to configure the aforementioned third link. Through the first power divider and the second power divider, the six columns of oscillators can output four RF signals, so that the antenna device is configured as a software-defined antenna (SDA) and can be configured as four-channel six-sector (4T6S), which can achieve capacity expansion and capacity enhancement of the LTE network. At the same time, the distance between the first column of oscillators 1 and the third column of oscillators 3, as well as the distance between the fourth column of oscillators 4 and the sixth column of oscillators 6 are both small, which will not lead to the generation of grating lobes, can support the smooth evolution of 5G communication systems, and can help operators save fixed investment and operating expenses.

[0076] Figure 17 is a schematic diagram of another antenna device provided in an embodiment of the present application. Referring to Figure 17, in a possible implementation, the third transceiver link includes a fourth link. The power division network 18 includes a third power divider, a fourth power divider, and a fifth power divider. The first column of vibrators 1 and the fourth column of vibrators 4 are combined through the third power divider to output the fifth RF signal. The power ratio output by the third power divider is x:1, where x is 0.1, 0.2, 0.3, 0.4, or 0.5. The second column of vibrators 2 and the fifth column of vibrators 5 are combined through the fourth power divider to output the sixth RF signal. The power ratio output by the fourth power divider is 1:1. The third column of vibrators 3 and the sixth column of vibrators 6 are combined through the fifth power divider to output the seventh RF signal. The power ratio output by the fifth power divider is 1:y, where y is 0.1, 0.2, 0.3, 0.4, or 0.5. The power ratio output by the third power divider is symmetrically configured with the power ratio output by the fifth power divider. For example, the power ratio output by the third power divider is 0.5:1, and the power ratio output by the fifth power divider is 1:0.5; for example, the power ratio output by the third power divider is 0.4:1, and the power ratio output by the fifth power divider is 1:0.4. The phase difference between the two oscillators corresponding to each power divider is 0. In this embodiment, the third power divider, the fourth power divider, and the fifth power divider can all be connected to the sixth RF unit to configure the above-mentioned fourth link, so that the antenna device is configured as an SDA antenna, and can be configured as two-channel nine-sector (Two Transmitter For Nine Sectors, 2T9S), which can achieve further expansion of the LTE network.

[0077] In one possible implementation, the fifth RF signal includes three first RF signals with different phases, the three first RF signals covering three split first sectors, and each first RF signal covering a corresponding first sector. The sixth RF signal includes three second RF signals with different phases, the three second RF signals covering three split second sectors, and each second RF signal covering a corresponding second sector. The seventh RF signal includes three third RF signals with different phases, the three third RF signals covering three split third sectors, and each third RF signal covering a corresponding third sector.

[0078] As previously described, each antenna unit in each element column can be a dual-polarized antenna unit, so that each element column can have two output ports. In this embodiment, the fifth RF signal, the sixth RF signal, and the seventh RF signal are each output from the corresponding two output ports. In other words, the antenna device can be configured with a total of six antenna output ports, and these six antenna output ports can be respectively connected to the six RF channels of the sixth RF unit 12.

[0079] In one possible implementation, the three first RF signals are i1, i2, and i3, and the three first RF signals can be obtained by adjusting the phases of the original RF signals ia, ib, and ic transmitted by the antenna through software. For example, appropriate baseband weights can be configured in software to match the original RF signals with the corresponding baseband weights to obtain the corresponding first RF signals i1, i2, and i3. In one possible implementation, for the ports combined by each power divider, the baseband weights can be (0° / 120° / 240°), (0° / -120° / -240°), (0° / 0° / 0°), and the two ports of the RF unit corresponding to the fifth RF signal can output signals i1, i2, and i3, i1=iaⅹ0°, i2=ibⅹ0°, i3=icⅹ0°. Similarly, the three second RF signals are i4, i5, and i6, and the two ports of the RF unit corresponding to the sixth RF signal can output signals i4, i5, and i6, i4 = iaⅹ120°, i5 = ibⅹ(-120°), and i6 = icⅹ0°. The three third RF signals are i7, i8, and i9, and the two ports of the RF unit corresponding to the seventh RF signal can output signals i7, i8, and i9, i7 = iaⅹ240°, i8 = ibⅹ(-240°), and i9 = icⅹ0°. Therefore, by configuring the above baseband weights, a split beam can be formed, which can be specifically configured as 2T9S, with a larger LTE network capacity.

[0080] It should be noted that the first RF unit, the second RF unit, the third RF unit, the fourth RF unit, the fifth RF unit and the sixth RF unit involved in any embodiment of the present application may be the same RF unit or different RF units.

[0081] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible.
