ANTENNA, BASE STATION AND BEAM PROCESSING METHOD

FIELD OF THE INVENTION

The present invention relates to antenna technologies and, in particular, to an antenna, a base station, and a beam processing method.

BACKGROUND OF THE INVENTION

With the development of mobile communications, users have more and more demands on the capacity of a communication system. One of the effective methods of efficiently increasing the capacity of the system at low cost is the use of a multi-beam antenna to increase sectors of an existing network. In general, the multi-beam antenna typically includes a beam-forming network and a set of antennas connected to the network, where the beam-forming network is capable of receiving at least two paths of incoming signals through a gateway. base station signal, perform phase and amplitude adjustment for the input signal to generate output signals having a predefined phase and amplitude, and then output the output signals to the antenna array through a signal port antenna, and the set of antennas is configured to transmit the output signals by using the beam corresponding to the output signals. Normally, each signal path corresponds to a beam after the adjustment is made. Therefore, the antenna is capable of generating at least two different beams to increase the capacity of the system.

The typical application structure for the prior art antenna beamforming network is a Butler matrix (Butler). For example, the Butler matrix can

2/37 include six hybrid couplers and four phase shift devices, where the six hybrid couplers are categorized into three layers with two hybrid couplers on each layer, and a phase shift device is defined between two layers of hybrid couplers for delay output signals from the hybrid couplers to a specific phase and then output signals. The Butler matrix can eventually output signals with a predefined phase and amplitude, and send the output signals to a directional network of antennas. For example, suppose that the matrix has four output ports, which are respectively connected to four sets of antennas, after the input signals are processed by the Butler matrix, the phases of the output signals from adjacent output ports may have a difference of 90 degrees in turn, and the amplitudes of the four output signal paths are distributed at 0.414: 1: 1: 0.414.

The beamforming network on the previous antenna uses many hybrid couplers and phase shift devices, and hybrid couplers and phase shift devices are connected using complex structures, which results in high antenna costs at present.

DETAILED DESCRIPTION OF THE MODALITIES

In embodiments of the present invention, to simplify the structure of a beam-forming network in an antenna and to reduce the cost of the antenna, a power-splitting apparatus is defined in the beam-forming network. The power-splitting device, for example, is an unequal power-splitting device. The unequal power splitting apparatus, for example, can be implemented using an unequal power divider or an unequal hybrid coupler. Compared to the prior art, where the prior art beam forming network does not have a power splitter configured to perform amplitude adjustment for signals, but uses only a hybrid coupler and a phase shift device to perform adjustment amplitude for signals, complex vector operations are involved in such an adjustment mode, and many hybrid couplers and complex connection relationships are necessary for the implementation of specific amplitude adjustment. However, modalities of the present invention mainly use a power division apparatus to implement the amplitude adjustment, which can allow the amplitude adjustment for signals to be very convenient, thus reducing the number of devices, such as hybrid couplers, and simplifying the structure of

7/37 beam forming network.

Mode 1

Figure 1 is a schematic structural diagram of an antenna according to an embodiment of the present invention. The antenna is an antenna capable of generating multiple beams. For example, a first input signal and a second input signal are respectively inserted via two antenna base station signal ports, and after the internal signal processing by the antenna, the first input signal can produce a output signal that corresponds to a first beam through an antenna output port, and the second input signal can produce an output signal that corresponds to a second beam through an antenna output port, thus generating multiple beams across antenna.

As shown in Figure 1, the antenna includes a beamform network 11 and multiple sets of antennas 12, where the beamform network 11 includes a hybrid network 22 and a power splitter 21.

The hybrid network 22 includes base station signal ports 13 for communication with a base station transceiver. For example, there can be at least two base station signal ports 13. The base station signal ports belong to hybrid network 22 and are capable of receiving signals sent by the base station transceiver. The hybrid network 22 is configured to perform phase adjustment for the signals received from the base station transceiver, generate signals having a predefined phase, and send the signals to the power splitter 21. The hybrid network 22 can also perform the adjustment of signal amplitude.

8/37

The signals can be multipath signals that, for example, can have two signal paths. Each signal path is output to a power splitter, and the power splitter is capable of converting one signal path to two signal paths and outputting both signal paths.

The predefined phase is a phase obtained after the signals are processed by the hybrid network 22 of the beamforming network. For example, signals sent by the base station transceiver enter the hybrid network 22 through the base station signal ports, and after the phase adjustment performed by the hybrid network 22, the obtained phase is referred to as the default phase (for example, + 180 degrees).

The power splitter 21 includes multiple antenna signal ports 14 to communicate with the antenna arrays, where each antenna signal port 14 is connected to an array of antennas 12, and the power splitter is configured to perform the amplitude adjustment for the signals received from the hybrid network 22, and to emit multipath signals having a set amplitude and the predefined phase for the multiple sets of antennas. Typically, the connection of antenna signal ports 14 to antenna assemblies 12 means that antenna signal ports 14 are connected to antenna units in antenna assemblies 12. Specifically, antenna assemblies 12 are typically composed of multiple antenna units, where each antenna unit has a radiator for transmitting signals. The antenna signal ports 14 are actually connected to each antenna unit in the

9/37 sets together sets together,

in antennas 12. Besides that, in antennas form a beam the joint anoints in antennas 12 c

corresponding s

to allow the same modalities the em have at least polarization between them, sets of antennas of the present invention

When defining the amplitude adjustment they are exemplary desired amplitude 12 in the modalities of also sets having the same apparatus for signals division of will be very power 21, convenient, and can be obtained directly by adjusting the power division apparatus 21 Compared to the amplitude adjustment mode of vector interconnection operations in which only equipment, such as hybrid couplers, is used, this method reduces the number of devices, such as hybrid couplers, and simplifies the structure of the training network. beam.

The multiple sets of antennas 12 are configured to receive the multipath signals emitted by the power splitter and to transmit the multipath signals, wherein the transmitted multipath signals have a set phase and the set amplitude. The set phase is the phase of the signals to be transmitted through the antenna sets 12. As shown in Figure 1, after being emitted from the hybrid network 22, the signals pass through the power splitter 21, and then are sent to antenna sets 12 and transmitted by antenna sets 12. In multipath signals received from the power splitter, the default phase of each signal path is the same as the set phase of the

10/37 signals when signals are transmitted, or the predefined phase of at least one signal path is opposite to the set phase of signals when signals are transmitted. For example, the default phase of the signals emitted by the hybrid network 22 is +180 degrees, and the set phase required by the antenna sets 12 is also +180 degrees, so the phase does not need to be changed after the signals are emitted from the hybrid network 22, and signals are sent directly to antenna sets 12, or the set phase required by antenna sets 12 is -180 degrees, where the predefined phase is opposite the set phase, so the phase must be adjusted after the signals are emitted from the hybrid network 22, and the signals are transmitted through the antenna sets 12 after their phase is converted to -180 degrees. For detailed phase conversion modes, see the following modalities.

In the modalities that follow, firstly, in cases where the predefined phase is opposite to the aggregate phase and where the predefined phase is the same as the aggregate phase are described, secondly, for the case where the predefined phase is opposite to the set phase, the reverse processing modes for using the reverse set in the antenna set and the reverse processing for using a 180 degree phase shifter are described, and in the specific descriptions, specific structures of four sets, eight sets or six sets, and the specific structures shown in the attached drawings are used as examples, and the signal transmission process is used as an example. However, people

11/37 skilled in the art should understand that the specific modalities are not limited to the preceding structures, and apply to the signal reception process, which is opposite to the signal transmission process. In the process of receiving signals, multiple sets of antennas receive

signs of multiple paths with a set phase and a amplitude as a whole, a power division device effect the amplitude adjustment for multiple signals ways and then sends the signals to a network

hybrid, the hybrid network performs the phase adjustment and amplitude adjustment for the signal and then sends the signals

for one base station transceiver. In the signs of multiple paths received by the splitting device power, a predefined phase of each signal path is

the same as the set phase of the signals when the signals are received by the antenna sets, or the predefined phase of at least one signal path is opposite to the set phase of the signals when the signals are received by the antenna sets.

Mode 2

Ά Figure 2 is a schematic structural diagram of an antenna according to another embodiment of the present

invention. This modality is approximately the case where the phase preset is opposite to the set phase and

reverse processing by using the reverse set in the set of antennas are implemented.

How shown in Figure 2, the antenna has a network of formation bundles and antenna assemblies designed in set, where at least one inverse set is defined

in antenna assemblies, a power phase of the

12/37 reverse set is opposite to the power phases of other sets of antennas, the reverse set is used as a phase shift unit that is capable of changing a predefined phase of the signals received from the beamform network to a set phase and then transmit the signals, or change a set phase of received signals to a predefined phase and then send the signals to the beamforming network.

In essence, the phase adjustment for signals is carried out together by the reverse set and the beamforming network. The antenna sets implement part of the beam adjustment network phase adjustment function, so that the structure of the beam forming network is further simplified and the cost of the antenna is reduced.

The antenna may include a beamform network 11 and multiple antenna sets 12 (Figure 2 shows four antenna sets, for example), where the beamform network 11 includes at least two base station signal ports 13 and multiple antenna signal ports 14, and each antenna signal port 14 is connected to a set of antennas 12. The base station signal ports refer to ports for communication with a base station transceiver side, and the antenna signal ports refer to ports for communicating with an antenna array side. The antenna beamforming network may include a power splitter 21 and a hybrid network 22. Base station signal ports 13 are configured on hybrid network 22, antenna signal ports 14 are defined on the power division 21, and the power division apparatus 21 and the hybrid network

13/37 are connected.

The antenna includes at least two base station signal ports 13, because the antenna must generate multiple beams. Typically, the output signals obtained after signals enter through each base station signal port 13 and processed by the beamforming network 11 correspond to a beam. Therefore, to generate multiple beams, it is usually necessary to have at least two base station signal ports. Generally, there are also multiple sets of antennas 12, such as four or eight sets of antennas, and to ensure isolation between sets of antennas, there are specific spatial gaps between sets. Correspondingly, in order to output the output signals to the antenna arrays, there are also multiple antenna signal ports to connect with the antenna arrays.

Specifically, the base station signal ports 13 are used to receive input signals sent by the base station transceiver, where the input signals refer to signals from the base station to be transmitted by the antenna. After receiving the input signals from the base station signal ports 13, the hybrid network performs phase adjustment and amplitude adjustment for the input signals to generate multipath intermediate output signals, and outputs the intermediate output signals multipath to the power splitter

21.

After receiving the intermediate multipath output signals, the power splitter is essentially configured to convert the intermediate multiport output signals

14/37 paths for multipath output signals, perform power allocation between multipath output signals, so that multipath output signals have a predefined amplitude distribution, that is, an amplitude distribution as a whole. For example, the set amplitude for four signal paths

0.412: 1: 1: 0.412.

The power splitter 21 outputs multipath output signals to antennas 12 through the ports of each antenna signal port 14 on multiple antenna signal sets 14, where it sends an output signal path to a set of antennas 12.

As explained above, in this embodiment, the output signals emitted by the beamform network 11 through the antenna signal ports 14 have the amplitude distribution as a whole. However, the difference between the beam forming networks in this modality, and the prior art is that, the output signals received by the beam forming network 11 of the present modality do not have a set phase required by the antenna sets, where the set phase refers to a phase of the signals to be transmitted by the antenna sets to the air (in the process of receiving signals, the set phase refers to a phase of the signals received by the antenna sets from the air), and, the multipath output signals, a predefined phase of at least one output signal path is opposite to the assembly phase, whereas in the prior art, the output signals from the beamform network have a predefined set phase distribution, where the predefined phase refers to a phase of the signals

15/37 transmitted by the hybrid network to the power splitter (in the process of receiving signals, the default phase refers to a phase of the signals sent by the power splitter to the hybrid grid).

For example, assume that the set phases of the corresponding output signals for the four sets of antennas must be +90 degrees, 0 degrees, -90 degrees, and -180 degrees, that is, the difference between the adjacent output signals is -90 degrees, output signals from the prior art beam forming network already have the preceding phases, while those from the beam forming network 11 of the present embodiment can be -90 degrees, -180 degrees, -90 degrees, and - 180 degrees (shown in Figure 2), which are not the set phases, and the predefined phases of two output signal paths are opposite the set default phase. The previous set phases are relative values instead of absolute values, that is, the phase values of all antenna sets are normalized against the phase value of one of the antenna sets. The phase values referred to in this modality and the modalities that follow are also relative phase values.

The multiple antenna sets 12 of this modality include at least one reverse set, where the reverse set refers to a set of antennas whose power phase is opposite to a power phase of another antenna set, and the reverse set is the phase shift unit. For example, antenna array 12a and antenna array 12b shown in Figure 2 are antenna sets having opposite supply phases, in

16/37 that the antenna array 12a performs the reverse processing for the phase (-90 degrees) of the corresponding signals to obtain the predefined array phase (+ 90 degrees), while the antenna array 12b does not process the phase of the antenna signals. output. Similarly, antenna array 12c and antenna array 12d shown in Figure 2 are also antenna sets with opposite supply phases, where antenna array 12c performs reverse processing for the (-180 degrees) phase of the corresponding signals to obtain the predefined set phase (0 degrees), while the antenna set 12d does not process the phase of the output signals.

After the processing described above, the preset phases -90 degrees, -180 degrees, -90 degrees, and -180 degrees of the output signals from the beamform network 11 are converted to the preset assembly phases +90 degrees, 0 degrees , -90 degrees, and -180 degrees for antenna sets. So far, the output signals in the antenna sets have the set amplitude distribution and the set phase distribution, and the signals can be transmitted via a beam corresponding to the array amplitude and the set phase in the set of antennas. antennas. That is, the four sets of antennas 12 shown in Figure 2 can form a bundle together according to the previous set amplitude and previous set phase distribution.

The following describes the reverse function performed on the previous antenna sets. Before input signals from the base station transceiver were received, the power phases of the antenna sets were previously

17/37 defined for phase inversion. The phase inversion for the power phases of the previous antenna sets can be implemented by means of definition methods commonly known in this field. For example, for half-wave dipole antenna assemblies, the connection mode between the internal and external connectors of a coaxial cable and the power point of an oscillator arm can be changed to change the power phase of the antenna assemblies. For antenna sets of other types, reverse definition is also performed using common art and will not be described here. By inverse definition for antenna sets, after the signals are received, the antenna sets perform reverse processing for the signal phase, for example, changing the phase by -180 degrees or +180 degrees. For electromagnetic signals that are periodic signals, a signal period is 360 degrees. Therefore, the same effect in essence is obtained by changing the original signals by -180 degrees or 180 degrees.

Based on the previous description, the antenna of this modality, a part of the prior art beam forming network functions are implemented by the antenna assemblies, and the beam forming network and the antenna assemblies work together to carry out the adjustment phase for input signals. That is, the prior art beam forming network is capable of adjusting the input signals by itself to obtain the output signals with a set phase and set range, however, the output signals obtained by The beamforming network of this modality itself has an overall amplitude, and only part of the multiple output signals has a phase

18/37 set (for example, a phase of an output signal path is -90 degrees, and signals from this phase are supposed to be output to the antenna assemblies), but some of the output signals have phases that are opposite to the set phase (for example, a phase of an output signal path is -90 degrees, but the phase of the signals to be emitted to the antenna sets must be +90 degrees), and in this case, using the reverse functionality of antenna sets, the array phase is achieved after the antenna sets perform reverse phase processing.

The following mode 3 and mode 4, for using a four-set antenna and an eight-set antenna as examples, respectively, describe in detail the solution where the phase shift unit is an inverse set in the antenna sets. Based on these two modalities, it is evident that the structure of the beamforming network using this solution is very simplified.

Modalities 3

Figure 3 is a schematic structural diagram of an antenna according to yet another embodiment of the present invention. This mode shows an antenna of four sets, that is, an antenna having four sets of antennas 12.

As shown in Figure 3, the antenna includes four sets of antennas 12 (the shapes indicated by 12a, 12b, 12c, and 12d in the figure represent the antenna sets). An antenna beamforming network includes a hybrid network 22. The hybrid network 22 of this modality only uses one

19/37 90 degree hybrid coupler. Specifically, other structures can also be used in specific modalities, for example, a combination of a hybrid coupler of

180 degrees and a phase shifter can be used.

The hybrid network 22 includes two base station signal ports 13 in Figure 3). The beam-forming network also includes two power-splitting devices (the power-splitting devices are, for example, unequal power splitters), which are a first power-splitting device 21a and a second power-splitting device 21b respectively, and each power splitter has two antenna signal ports 14. The antenna signal ports of the power splitter devices are connected to the antenna assemblies. The connection lines between the four antenna signal ports 14 and the four antenna sets 12 are respectively represented as 14a, 14b, 14c, and 14d.

The 90-degree hybrid coupler includes two output ports, that is, a first output port M1 and a second output port M2, where the first output port Ml is connected to the first power splitter 21a, and the second output port M2 is connected to the second power splitter 21b. Each power splitter includes a first output port and a second output port, which are the two antenna signal ports 14 shown in Figure 3. For example, the two antenna signal ports of the first power splitting devices 21a are connected to antenna assemblies 12a and 12c through connection lines 14a and 14c, and the two

20/37 antenna signal ports of the second power splitter 21b are connected to antenna assemblies 12b and

12d through connection lines 14b and 14d. As shown in Figure 3, power phases of the antenna assemblies

12a and 12c are opposite, and the power phases of the antenna assemblies 12b and 12d are opposite. That is, one of the two output ports of the power division device is connected to a phase shift unit, that is, the reverse set, and the other is connected directly to the set of antennas.

The principle of operation of the structure of this modality is described below by means of examples.

Let's assume that a signal is inserted through the base station signal port A, and then the 90 degree hybrid coupler of the hybrid network 22 performs the phase adjustment and amplitude adjustment for the signal, two paths of intermediate output signals are issued. That is, SI (-90) is emitted through the first output port M1 of the 90-degree hybrid coupler, where SI (-90) represents SI signal and a phase of the SI signal is -90 degrees (ie, a phase predefined); S2 (-180) is output via the second predefined port).

splitting apparatus for the second power splitting apparatus 21b.

Each power splitter is capable of dividing the intermediate output signal received into two

21/37 paths of output signals having the same phase. For example, after passing the first power splitter 21a, SI (-90) is emitted as SI (-90) and S3 (-90), where the phases of the two signals are the same and both are -90 degrees as the input phase initially SI (-90) (that is, still the predefined phase), after passing the second power division apparatus 21b, S2 (-180) is output as S2 (-180) and S4 (- 180), and likewise, the phases of the output signals are the same and are both -180 degrees. However, the power division devices have changed the signal amplitude allocation, so that the output signals have the predefined set amplitude. As shown in

Figure 3, amplitude distribution of the four paths of output signals emitted through the two power dividers 21a

21b are the predefined amplitude distribution values, that is,

0.412: 1: 1: 0.412.

The four paths of SI output signals emitted by the two power dividers are sent to the four sets of antennas, respectively, through connection lines 14a, 14b,

14c, and 14d. As shown in Figure

3, the power phases of the antenna sets 12a and 12c are opposite, the antenna sets 12a can perform the reverse processing for SI (-90) and convert it to SI (+ 90) (i.e., the set phase ). Similarly, the phases of

feeding antenna sets 12b and 12d are opposite, the set of 12d antennas can perform processing reverse for S4 (-180) and convert it to S4 (0) (that is, the

whole phase).

22/37

As shown in Figure 3, after the processing described above, the signals in the antenna arrays have the predefined array phase distribution and the predefined array amplitude distribution, and a corresponding beam can be formed for the antenna arrays to transmit the signals.

In addition, the degree of isolation between the two base station signal ports of the 90 degree hybrid coupler of this modality is high, and the power division devices are able to flexibly adjust the amplitude of each output signal path. according to current requirements. If a signal is inserted through port B, the antenna processes the signal in a process similar to the procedure described previously, which is not described here several times. In addition, as described above, the 90 degree hybrid coupler and uneven power dividers in Figure 3 can be replaced with other structures with equivalent functions.

Based on the previous description and as shown in Figure 3, the beamforming network in this embodiment actually uses only a 90 degree hybrid coupler and two unequal power dividers to implement the set amplitude and set phase in the antenna sets (antenna sets assist in reverse processing). In comparison with the prior art, the prior art normally needs to use six 90 degree hybrid couplers and four phase shifters to implement the predefined set amplitude and set phase in the antenna sets. Thus, it is evident that this modality greatly simplifies the structure of the network

23/37 of equipment within the network, and correspondingly also simplifies the antenna structure and reduces the cost of the antenna.

Mode 4

Figure 4 is a schematic structural diagram of an antenna according to yet another embodiment of the present invention.

This modality shows an antenna of eight sets, that is, an antenna with eight sets of antennas

As shown in Figure 4, the antenna includes eight sets of antennas 12. An antenna beamforming network includes a hybrid network 22.

hybrid network 22 of this variant uses four 90 degree hybrid couplers and two 45 degree phase shifters. In particular, hybrid network 22 includes a first 90-degree hybrid coupler 22 and a second 90-degree hybrid coupler 22d in layer 1, and a third 90-degree hybrid coupler 22b and a fourth 90-degree hybrid coupler 22c in layer 2 (layer 1 or layer 2 indicates the first layer or the second layer shown in the figure), where the first 90 degree electric 22a and the third hybrid 90 degree coupler 22b are opposite each other, and the second 90 degree hybrid coupler 22d and the fourth 90 degree hybrid coupler 22c are opposite each other. One outlet port 22a of the first 90 degree hybrid coupler is connected to the third 90 degree hybrid coupler 22b via the -45 degree phase shifter, and another outlet port is connected to the fourth 90 degree hybrid coupler 22c. One outlet port of the second 90 degree hybrid coupler 22d is

24/37 connected to the fourth 90 degree 22c hybrid couplers via the -45 degree phase shifter, and another output port is connected to the third 90 degree 22b hybrid coupler. Each output port of the third 90-degree hybrid coupler 22b and the fourth 90-degree hybrid coupler 22c is connected to a power splitter.

The beam forming network includes four power-splitting devices, which are represented by 21a, 21b, 21c, and 21d, respectively. Power splitting devices also use unequal power splitters as examples. Each power splitter includes a first outlet port and a second outlet port. The two output ports are the two antenna signal ports 14 of each power splitter shown in Figure 4. The two antenna signal ports of the power splitter are connected to the antenna assemblies, where one is connected to the phase shift unit and the other is connected to the antenna array.

The connection structures of the hybrid couplers, phase shifters, power dividers, and antenna assemblies are shown in Figure 4 and will not be described here. The working principle of the structure of this modality is described below by means of examples.

Suppose a signal is inserted through the base station signal port A, after passing the first 90 degree hybrid coupler 22a on hybrid network 22, the signal emits two paths of intermediate output signals, that is, S (-90 ) and S (-180). That is, two signal paths whose phases are -90 degrees and -180 degrees, respectively, are emitted.

25/37

After S (-90) passes the 45 degree phase shifter, the phase changes to -135 degrees, that is, S (-135). The S (135) passes another 90 degree hybrid coupler 22b and emits S (-225) and S (-315) (that is, the predefined phases). S (225) and S (-315) are respectively inserted for two unequal power dividers, where S (-225) is inserted for the 21s power divider and S (-315) is inserted for the power divider 21b. S (-180) enters directly into the fourth 90-degree hybrid coupler 22c, and emits two S (-270) and S (-360) signals (ie, the preset phases) through the two antenna signal ports of the fourth coupler 90 degree hybrid 22c; S (-360) is inserted for the power divider 21c and S (-270) is inserted for the power divider 21d.

The four power dividers 21a, 21b, 21c, and 21d are mainly configured to perform amplitude adjustment for received signals, so that the output signals have the predefined set amplitude distribution. (Figure 4 does not show the amplitude distribution values, which can be, for example, 0.412 / 0.412 / 1/1/1/1 / 0.412 / 0.412, or other amplitude distribution values, the amplitude distribution values can be flexibly adjusted using the

The phases of received signals are not changed. Thus, the phases of the signals emitted by the four power dividers for the eight sets of antennas 12a to 12h are -315, -270, -225, -360,

-315, - -270, -225, and -360 in order, what are shown in before inversion phase in Figure 4. In one mode similar, after the exit signs

26/37 reach the antenna sets, supply phases of a part of output signals are opposite to the power phases of the antenna sets, therefore, the corresponding antenna sets will perform reverse processing for this part of output signals.

For example, as shown in Figure

4, the power phases of the antenna assemblies 12a,

12b,

12c, and 12h are positive, while phases of the corresponding received signals are negative. Therefore, previous antenna sets can perform inversion of the received output signals to convert the output signals to the set phase.

After inversion, the phase distribution of the corresponding output signals for the antenna sets is -135 (-315 + 180), -90 (-270 + 180), -45 (-225 +

180), 0 (Actually, the phase is not changed, but only represented with another value. Because an electromagnetic wave signal is a signal having a period of 360 degrees. 360 and 0 are the same in essence. For example, 0 , can be obtained as follows: -360 + 360. A period is 360 degrees and mx360 can be added, where m is a positive integer, a negative integer or 0), +45 (-315 + 360), +90 ( -270 + 360), +135 (-225 + 360), + 180 (-360 - 180 + 720).

In this mode, after a signal is inserted through port B, the signal phases of the eight sets of antennas have a difference of -135 degrees in turn, after a signal is inserted through port C, the signal phases of the eight sets of antennas have a difference of 135 degrees in turn, and after a signal is inserted through port D, the signal phases of the eight sets of antennas have a difference of -45 degrees

27/37 in turn. The specific signal process and principle are similar to those when the signal is received through port A, and will not be described here several times. In addition, the degree of isolation between the four base station signal ports A, B, C, and D of the present mode is high, and the power dividers are able to flexibly adjust the amplitude of each signal path. output according to actual requirements.

This modality greatly simplifies the structure gives training network beam, reduce complexity in interconnection of equipment inside from the Web, correspondingly, it also simplifies the structure gives

antenna and reduces the cost of the antenna.

In mode 3 and mode 4 above, the reverse set is used as the phase shift unit as an example. In the following modality 5, Figure 5 and Figure 6 show another solution, which is approximately the case where the predefined phase is opposite the set phase and the phase shift unit is a 180 degree phase shifter, and reverse processing is implemented using the 180 degree phase shifter.

Mode 5

As shown in Figure 5 and Figure 6, a phase shift unit is a 180 degree phase shifter, and the antenna includes at least one 180 degree phase shifter. The 180-degree phase shifter, respectively, is connected to a power splitter and a set of antennas, and is configured to perform phase inversion for signals with a predefined phase opposite the set phase that are received

28/37 by the power division apparatus, and emits signals to the antenna array, or reverses signals having a set phase opposite the predefined phase that are received by the antenna array, and outputs signals to the apparatus power division.

Figure 5 is a schematic structural diagram of an antenna according to yet another embodiment of the present invention. As shown in Figure 5, compared to the antenna structure shown in Figure 3, a major difference from this modality lies in the fact that the phase shift unit is a 180 degree phase shifter 51 defined between the antenna array and the unequal power divider. In this case, the antenna array is the same as the state of the art and no reverse array is defined. The 180-degree phase shifter 51 is used to perform phase inversion. The principle of operation of this antenna is the same as the principle of the antenna shown in Figure 3 and is not described here repeatedly.

Figure 6 is a schematic structural diagram of an antenna according to yet another embodiment of the present invention. As shown in Figure 6, compared to the antenna structure shown in Figure 4, a major difference from this modality lies in the fact that the phase shift unit is a 180 degree phase shifter 51 defined between the antenna array and the unequal power divider. In Figure 6, 21a, 21b, 21c, and 21d are four power-splitting devices, for example, unequal power splitters. One of the two output ports of each power splitter is connected

29/37 to the antenna array via the 180-degree phase shifter 51, and another outlet port is connected directly to the antenna array. The eight sets of antennas 12a to 12h in Figure 6 are the same as those of the prior art and no reverse set is defined. The 180-degree phase shifter 51 is used to perform phase inversion. The working principle of this antenna is the same as the antenna principle shown in Figure 4 and is not described here repeatedly.

Figure 7 is a schematic structural diagram of an antenna according to yet another embodiment of the present invention. As shown in Figure 7, no phase shift units are required because the predefined phase and the set phase are the same in this mode. In particular, the antenna includes a beam-forming network and antenna assemblies 12, where the beam-forming network includes a hybrid network 22 and a power splitting apparatus 21.

Hybrid network 22 includes two 90 degree hybrid couplers 71 in layer 1 and two 180 degree 72 hybrid couplers in layer 2. As shown in Figure 7, each outlet port of each 90 degree hybrid coupler 61 is connected to a coupler 180 degree 72 hybrid, one of the two output ports of each 180 degree 72 hybrid coupler is connected to the power splitter 21, and one

30/37 another output port is connected directly to the antenna array 12. Each output port of the power splitter 21 is connected to a set of antennas. No phase inversion is necessary for this mode and, therefore, the power splitter 21 only performs the amplitude adjustment of the received signals. For example, as shown in Figure 7, the received signals are divided into two 0.8: 0.6 signal paths.

The antenna of the structure in this modality is configured to transfer signals from a port A, a port B, and a port H, respectively, to the antenna sets, and enables the output set phases of the antenna sets for signals inserted through the port A have a difference of 90 degrees in turn, the output set phases of the antenna sets for signals inserted through port B have a difference of 90 degrees in turn, and the output set phases of the antenna sets antennas for signals inserted through port H to be the same. At the same time, the degree of isolation between the three ports A, B, and H is high. In addition, this modality can also allow a part of the hybrid network in the beamforming network to be connected directly to the antenna assemblies, and a part to be connected to the antenna assemblies by means of a power splitter.

The foregoing embodiments describe the solutions of the present invention in detail using the signal transmission process, as an example. Those skilled in the art should understand that the antenna can also receive signals, that is, after receiving signals, the antenna assemblies transfer the signals to the

31/37 beam. Processing for receiving signals is opposite to processing for transmitting signals. The following is just a brief description of the processing for receiving signals from: for example, when the multiple set phases are opposite a predefined phase, a phase shift unit changes phases of the set of signals received by the antenna sets to the predefined phase and outputs the signals to a power splitter, the power splitter performs the amplitude adjustment for the received multipath signals having the predefined phase and outputs the multipath signals to a hybrid network, and the hybrid network performs phase adjustment and amplitude adjustment for multipath signals and then sends multipath signals to a base station transceiver. Once the power division apparatus is used, the structure of the antenna according to the modalities of the present invention is simplified for the process of transmitting signals or receiving signals.
