Background technique

In mobile communication, an antenna that uses a half-wave oscillator as a radiation module is usually used for communication. For example, in a system that supports MIMO (Multi Input Multiple Output) and diversity reception functions, each cell or sector is required to be equipped with multiple antennas, and the coherence of these antennas is required to be zero, while orthogonal polarization The antenna meets these requirements, so it can communicate through orthogonally polarized antennas. For orthogonally polarized antennas, the two half-wave oscillators are placed vertically on a plane, so as to realize the orthogonal polarization characteristics of the two antennas.

The half-wave vibrator has the advantages of simple engineering implementation and space saving. However, in related technologies, the working bandwidth of the half-wave oscillator is too narrow, which leads to the need for multiple independent half-wave oscillators and feeder systems to achieve multi-band coverage, which is already overwhelmed by the already crowded mobile base station antenna towers. However, if a new base station antenna tower is built, not only will the investment be huge, but also the land acquisition will be difficult.

Detailed ways

In order to make the objectives, technical solutions, and advantages of the present disclosure clearer, the following further describes the embodiments of the present disclosure in detail through specific implementations in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present disclosure, but not used to limit the present disclosure.

Example one

The antenna includes a radiating unit and a feeding unit, and a half-wave oscillator is usually used as the radiating unit. The half-wave oscillator includes two symmetrically arranged radiators, which has the advantages of simple engineering implementation and space saving. However, the working bandwidth of the half-wave oscillator cannot be too wide. If the working bandwidth is too wide, it will cause the antenna standing wave, beam width, and gain. Wait for deviation from the design value. Therefore, in the related art, the bandwidth of the half-wave oscillator is relatively narrow, and the cost is relatively high when realizing multi-band coverage.

In order to solve the above technical problems, embodiments of the present disclosure provide a half-wave vibrator. As shown in FIG. 1, the half-wave vibrator includes a first radiating arm 10 and a second radiating arm 20. Both the first radiating arm 10 and the second radiating arm 20 include two radiators arranged in a straight line and a connector arranged between the radiators, and the connector is used to disconnect or connect the two radiators in the radiating arm . Among the first radiating arm 10 and the second radiating arm 20, the radiator close to the other radiating arm is used to connect with the feeding unit 30. The radiator of the first radiating arm 10 and the radiator of the second radiating arm 20 are arranged symmetrically. In other words, the half-wave vibrator includes 4 radiators and 2 connectors. The first radiator 101 and the second radiator 102 are arranged on the same straight line, and the first connector 103 is arranged between the first radiator 101 and the second radiator 102. The first radiator 102 is formed between the second radiators 102, and the first connector 103 is used to disconnect the first radiator 101 and the second radiator 102, or to connect the first radiator 101 and the second radiator 102. The two radiators 102 are connected; the third radiator 201 and the fourth radiator 202 are arranged on the same line, and the second connector 203 is arranged between the third radiator 201 and the fourth radiator 202 to form a second radiator arm 20. The second connector 203 is used to disconnect the third radiator 201 and the fourth radiator 202, or to connect the third radiator 201 to the fourth radiator 202; and, the first radiator 101 and The fourth radiator 202 is symmetrically arranged (that is, the first radiator 101 and the fourth radiator 202 are the same, and the positions of the first radiator 101 and the fourth radiator 202 are symmetrical), the second radiator 102 and the third radiator 201 Symmetrically (that is, the second radiator 102 and the third radiator 201 are the same, and the positions of the second radiator 102 and the third radiator 201 are symmetrical), wherein the second radiator 102 is located near the first radiator arm 10 The radiator of the second radiating arm 20, the third radiator 201 is the radiator of the second radiating arm 20 close to the first radiating arm 10, and the second radiator 102 and the third radiator 201 are used to connect the feeding unit 30. It should be understood that the length of the radiator is related to its working frequency band. Therefore, by disconnecting and connecting the connector, the effective radiator of the radiating arm can be made into one or both ends, thereby changing the length of the effective radiator so that the radiating arm The working frequency band covers two working frequency bands, thereby increasing the bandwidth of the half-wave oscillator. For example, for the first radiating arm, when the first connector 103 connects the first radiator 101 and the second radiator 102, at this time, the first radiator 101 is connected to the feeding unit 30 through the second radiator 102, The effective radiators of the first radiator 10 are the first radiator 101 and the second radiator 102, and the working frequency band is the first frequency band (it should be understood that the first frequency band and the first radiator 101 and the second radiator 102 The length corresponds to); when the first connector 103 disconnects the first radiator 101 from the second radiator 102, at this time, only the second radiator 102 is connected to the feed unit 30, and the effective radiation of the first radiator arm 10 The body is the second radiator 102, and the working frequency band is the second frequency band (it should be understood that the working frequency band corresponds to the length of the second radiator 102). For the second radiating arm, see the description about the first radiating arm.

In the embodiments of the present disclosure, the radiator may be a metal radiator, and the metal radiator may be a printed vibrator or a die-cast vibrator. The length of the radiator can be flexibly set according to actual needs. Since the length of the radiator is related to the working frequency band of the radiator, the length of the radiator can be determined according to the working frequency band of the half-wave oscillator that needs to be designed. In this embodiment, the two radiators of the first radiating arm 10 may be the same or different, and the two radiators of the second radiating arm 20 may be the same or different.

In the embodiment of the present disclosure, the included angle between the first radiating arm 10 and the second radiating arm 20 may be greater than or equal to 90 degrees and less than or equal to 180 degrees. The angle between the radiating arms 20 is 180 degrees (that is, the first radiating arm 10 and the second radiating arm 20 are arranged on a straight line). Or, referring to FIG. 2, the angle between the first radiating arm 10 and the second radiating arm 20 is 90 degrees. Or, referring to FIG. 3, the angle between the first radiating arm 10 and the second radiating arm 20 is 120 degrees.

In the embodiments of the present disclosure, the states of the connectors in the two radiating arms may be different. For example, the first connector 103 connects the first radiator 101 with the second radiator 102, and the second connector 203 connects the third radiator 201 is disconnected from the fourth radiator 202. At this time, the working frequency band of the first radiating arm 10 is the first frequency band, and the working frequency band of the second radiating arm 20 is the second frequency band. In order to improve the radiation efficiency, the state of the connectors in the two radiating arms can be the same, that is, the state of the connector of the first radiating arm 10 (ie, the first connector 103) is the same as that of the connector of the second radiating arm 20 ( That is, the state of the second connector 203) is the same. For example, the first connector 103 and the second connector 203 may both be in a connected state. At this time, the first radiator 101 is connected to the second radiator 102, the third radiator 201 is connected to the fourth radiator 202, and the first radiator is connected to the fourth radiator. The working frequency bands of the radiating arm 10 and the second radiating arm 20 are both the first frequency band. Alternatively, the first connector 103 and the second connector 203 may both be in a disconnected state. At this time, the first radiator 101 and the second radiator 102 are in a disconnected state, and the third radiator 201 and the fourth radiator 202 are in a disconnected state. In the disconnected state, the working frequency bands of the first radiating arm 10 and the second radiating arm 20 are both the second frequency band.

In the embodiment of the present disclosure, referring to FIG. 4, the connector may be a switch, and the two ends of the switch are respectively connected to two radiators, and the disconnection and connection of the switch are controlled according to the frequency band of the signal to be sent or received, so as to achieve Switching of the working frequency band of the half-wave vibrator. In other words, one end of the first switch 103 is connected to the first radiator 101 and the other end is connected to the second radiator 102. One end of the second switch 203 is connected to the third radiator 201, and the other end is connected to the fourth radiator 202.

In the embodiment of the present disclosure, as shown in FIG. 5, the connector may be a reactance line, the two stages of the reactance line are respectively connected to the two radiators in the radiating arm, and the first stage of the first reactance line 103 is connected to the first radiator 101 , The other pole of the first reactance line 103 is connected to the second radiator 102, the first level of the second reactance line 203 is connected to the third radiator 201, and the other pole of the second reactance line 203 is connected to the fourth radiator 202 , Whether the two stages of the reactance line are connected is related to the frequency band of the signal of the input reactance line. In this embodiment, the reactance line has the following characteristics: when the frequency of the input reactance line signal is in the first frequency band, the two stages of the reactance line are in a connected state, and when the frequency of the input reactance line signal is in the second frequency band, the reactance line The two stages are disconnected. In other words, the signal in the first frequency band can be transmitted between the two stages of the reactance line, and the signal in the second frequency band cannot be transmitted between the two levels of the reactance line. In this way, for the first radiating arm 10, when the signal input to the first radiating arm 10 is in the first frequency band, the signal can pass through the first reactance line 103 to be transmitted between the first radiator 101 and the second radiator 102, The effective radiators are the first radiator 101 and the second radiator 102. When the signal input to the first radiating arm 10 is in the second frequency band, the signal cannot pass through the first reactance line, and the effective radiator is the second radiator 102. For the working principle of the second radiating arm 20, please refer to the working principle of the first radiating arm 10, which will not be repeated here. Using the reactance line as the connector can not only realize the disconnection and connection under different frequency bands, but also, because the two-stage disconnection and connection of the reactance line is related to the frequency of the input reactance line signal, it can be in the first frequency band and Signals in the second frequency band are simultaneously input to the first radiating arm 10, signals in the first frequency band are transmitted through the first radiator 101 and the second radiator 102, signals in the second frequency band are transmitted through the second radiator 102, In order to achieve simultaneous coverage of two frequency bands.

In the embodiments of the present disclosure, the reactance line can be a semi-rigid cable, of course, it can also be made of other materials.

In the embodiment of the present disclosure, the signal sent to the first radiating arm 10 and the signal sent to the second radiating arm 20 may have the same frequency band and a phase difference of 180 degrees.

The embodiments of the present disclosure provide a half-wave vibrator and a half-wave vibrator assembly. The half-wave vibrator includes a first radiating arm and a second radiating arm. Both the first radiating arm and the second radiating arm include two radiators arranged on a straight line and a connector arranged between the radiators, and the connector is used to disconnect or connect the two radiators in the radiating arm. Among the first radiating arm and the second radiating arm, the radiator close to the other radiating arm is used to connect with the feeding unit. The radiator of the first radiating arm and the radiator of the second radiating arm are symmetrically arranged. In some implementations, each radiating arm of the half-wave vibrator includes two radiators, and the two radiators can be connected or disconnected. When the two sections of radiator are disconnected, the effective radiator of the radiating arm is one section, and when the two sections of radiator are connected, the effective radiator of the radiating arm is two sections. When the effective radiator is one section and two sections, the radiation frequency is different, so that the working frequency band of the radiating arm can cover two frequency bands, which increases the working bandwidth of the half-wave vibrator and reduces the cost of realizing multi-band coverage.

Example two

In order to better understand the present disclosure, the embodiments of the present disclosure are described with the following examples. Referring to FIG. 6, the half-wave vibrator of the embodiment of the present disclosure includes a first radiating arm 10 and a second radiating arm 20. Both the first radiating arm 10 and the second radiating arm 20 include two sections of radiators arranged on a straight line and a reactance line arranged between the radiators. In the first radiating arm 10 and the second radiating arm 20, a radiator close to the other radiating arm is connected to the feeding unit 30. The radiator of the first radiating arm 10 and the radiator of the second radiating arm 20 are arranged symmetrically. That is to say, the half-wave vibrator includes 4 sections of radiator and 2 sections of reactance line. Among them, the first radiator 101 and the second radiator 102 are arranged on the same straight line, and the first reactance line 103 is arranged between the first radiator 101 and the line of reactance. Between the second radiators 102, the two levels of the first radiator 101 and the second radiator 102 are respectively connected to form the first radiator arm 10; the third radiator 201 and the fourth radiator 202 are arranged on the same straight line, The second reactance line 203 is arranged between the third radiator 201 and the fourth radiator 202, and its two levels are respectively connected to the third radiator 201 and the fourth radiator 202, thereby forming the second radiating arm 20, and the first The radiator 101 and the fourth radiator 202 are arranged symmetrically (that is, the first radiator 101 and the fourth radiator 202 are the same, and the positions of the first radiator 101 and the fourth radiator 202 are symmetrical), the second radiator 102 and the fourth radiator 202 are symmetrical. The three radiators 201 are arranged symmetrically (that is, the second radiator 102 and the third radiator 201 are the same, and the positions of the second radiator 102 and the third radiator 201 are symmetrical), wherein the second radiator 102 is the first radiator arm 10 is the radiator close to the second radiating arm 20, the third radiator 201 is the radiator close to the first radiating arm 10 in the second radiating arm 20, and the second radiator 102 and the third radiator 201 are connected to the feeding unit 30 .

In the embodiment of the present disclosure, when the first radiator 101 is connected to the second radiator 102, and the third radiator 201 is connected to the fourth radiator 202, the effective radiators of the first radiator arm 10 are the first radiator 101 and the second radiator. Two radiators 102, the effective radiators of the second radiator 20 are the third radiator 201 and the fourth radiator 202, and the working frequency bands of the two radiators are both the first frequency band; when the first radiator 101 and the second radiator The body 102 is disconnected, the third radiator 201 is disconnected from the fourth radiator 202, the effective radiator of the first radiator arm 10 is the second radiator 102, and the effective radiator of the second radiator arm 20 is the third radiator 201 , The working frequency band of the two radiators is the second frequency band.

In the embodiment of the present disclosure, the first reactance line 103 and the second reactance line 203 are the same.

In the embodiment of the present disclosure, for a signal with a frequency in the first frequency band, the two stages of the first reactance line 103 and the second reactance line 203 are in a zero impedance connection state. For a signal with a frequency in the second frequency band, the first reactance line 103 and The two stages of the second reactance line 203 are in a disconnected state. In other words, for a signal with a frequency in the first frequency band, the first radiator 101 and the second radiator 102 are equivalent to being in a connected state, and the third radiator 201 and the third radiator 201 are equivalent to being in a connected state. For a signal with a frequency in the second frequency band, the first radiator 101 and the second radiator 102 are equivalent to the disconnected state, and the third radiator 201 and the third radiator 201 are equivalent to the disconnected state. In this way, the working frequency bands of the first radiating arm 10 and the second radiating arm 20 can simultaneously cover the first frequency band and the second frequency band, so that the working judgment of the half-wave oscillator covers the first frequency band and the second frequency band at the same time. That is to say, for the first radiating arm 10, assuming that a signal of the first frequency band and a signal of the second frequency band are simultaneously input to the first radiating arm 10, the signal of the first frequency band can pass through the first radiator 101 and the second radiator 102. For transmission, the signal in the second frequency band can be transmitted through the second radiator 102, so that the signal in the first frequency band and the signal in the second frequency band can be simultaneously transmitted. The same is true for the second radiating arm 20. In the embodiment of the present disclosure, signals can be input to the first radiating arm 10 and the second radiating arm 20 at the same time through the radiating unit. The frequency band of the signal input to the first radiating arm 10 and the signal input to the second radiating arm 20 are the same, and the phases are different. 180 degree.

The first radiator 101 is the same as the second radiator 102, that is, the half-wave oscillator includes four segments of the same radiator. The lengths of the first radiator 101 and the second radiator 102 can be designed according to the working frequency band of the half-wave oscillator that needs to be designed. Assuming that the first frequency band is f ₁ , the second frequency band is f ₂ , the wavelength corresponding to the first frequency band is λ ₁ , and the wavelength corresponding to the second frequency band is λ ₂ , then f _{2 is} greater than f ₁ , λ _{1 is} greater than λ ₂ , and f ₂ in [1.8f _{_1,} 2.2f _1], the radiation length of the metal body is λ _2/4, the spacing between the two reactor line is smaller than λ _2/100, of _{^{length: λ 2 / (2ε 1/2)}} , Where ε is the dielectric constant of the material used to make the reactance line.

When the two sections of radiator are disconnected, the effective radiator of the radiating arm is one section, and when the two sections of radiator are connected, the effective radiator of the radiating arm is two sections. When the effective radiator is one section and two sections, the radiation frequency is different, so that the working frequency band of the radiating arm can cover two frequency bands, which increases the working bandwidth of the half-wave vibrator and reduces the cost of realizing multi-frequency coverage.
