技术领域Technical field
本公开实施例涉及但不限于通信技术领域,具体而言,涉及但不限于一种半波振子、半波振子组件及天线。The embodiments of the present disclosure relate to, but are not limited to, the field of communication technology, and specifically, to, but are not limited to, a half-wave oscillator, a half-wave oscillator component, and an antenna.
背景技术Background technique
移动通讯中,通常使用将半波振子作为辐射模块的天线进行通信。例如,在支持MIMO(Multi Input Multi Output,多输入多输出)和分集接收功能的系统中,要求每个小区或扇区配置多根天线,而且要求这些天线相干性为零,而正交极化的天线符合这些要求,因此,可以通过正交极化的天线进行通信。对于正交极化的天线,其为将两个半波振子在一个平面上垂直摆放,从而实现两个天线的正交极化特性。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.
半波振子具备工程实现简单、节省空间等优点。但是,相关技术中,半波振子的工作带宽太窄,导致在实现多频段覆盖时,需要多套独立的半波振子和馈线系统,对于本已十分拥挤的移动基站天线塔已经是不堪负重,而若新建基站天线塔,不仅投资巨大,且征地困难。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.

具体实施方式Detailed ways
为了使本公开的目的、技术方案及优点更加清楚明白,下面通过具体实施方式结合附图对本公开实施例作进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本公开,并不用于限定本公开。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.
实施例一Example one
天线包括辐射单元和馈电单元,通常使用半波振子作为辐射单元。半波振子包括两段对称设置的辐射体,具有工程实现简单、节省空间等优点,但是,半波振子的工作带宽不 能太宽,如果工作带宽太宽,会导致天线驻波、波束宽度、增益等偏离设计值。因此,相关技术中,半波振子的带宽较窄,在实现多频段覆盖时,成本较高。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.
为了解决上述技术问题,本公开实施例提供一种半波振子,参见图1所示,该半波振子包括第一辐射臂10和第二辐射臂20。第一辐射臂10和第二辐射臂20均包括设置在一条直线上的两段辐射体以及设置在辐射体之间的连接器,该连接器用于断开或连接辐射臂中的两段辐射体。第一辐射臂10和第二辐射臂20中,靠近另一辐射臂的辐射体用于与馈电单元30连接。第一辐射臂10的辐射体与第二辐射臂20的辐射体对称设置。也就是说,半波振子包括4段辐射体和2个连接器,其中,第一辐射体101和第二辐射体102设置在同一直线上,第一连接器103设置在第一辐射体101与第二辐射体102之间,从而组成第一辐射臂10,第一连接器103用于断开第一辐射体101与第二辐射体102之间的连接,或将第一辐射体101与第二辐射体102连接;第三辐射体201和第四辐射体202设置在同一直线上,第二连接器203设置在第三辐射体201与第四辐射体202之间,从而组成第二辐射臂20,第二连接器203用于断开第三辐射体201与第四辐射体202之间的连接,或将第三辐射体201与第四辐射体202连接;并且,第一辐射体101与第四辐射体202对称设置(即第一辐射体101与第四辐射体202相同,且第一辐射体101与第四辐射体202的位置对称),第二辐射体102与第三辐射体201对称设置(即第二辐射体102与第三辐射体201相同,且第二辐射体102与第三辐射体201的位置对称),其中,第二辐射体102为第一辐射臂10中靠近第二辐射臂20的辐射体,第三辐射体201为第二辐射臂20中靠近第一辐射臂10的辐射体,第二辐射体102和第三辐射体201用于连接馈电单元30。应当理解的是,辐射体的长度与其工作频段相关,因此,通过连接器的断开与连接,可以使得辐射臂的有效辐射体为一段还是两端,从而改变有效辐射体的长度,使得辐射臂的工作频段覆盖两个工作频段,从而增加了半波振子的带宽。例如,对于第一辐射臂,在第一连接器103将第一辐射体101与第二辐射体102连接时,此时,第一辐射体101通过第二辐射体102与馈电单元30连接,第一辐射臂10的有效辐射体为第一辐射体101和第二辐射体102,工作频段为第一频段(应当理解的是,第一频段与第一辐射体101和第二辐射体102的长度对应);在第一连接器103将第一辐射体101与第二辐射体102断开时,此时,只有第二辐射体102与馈电单元30连接,第一辐射臂10的有效辐射体为第二辐射体102,工作频段为第二频段(应当理解的是,工作频段与第二辐射体102的长度对应)。对于第二辐射臂,参见关于第一辐射臂的描述。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.
本公开实施例中,辐射体可以是金属辐射体,金属辐射体可以是印刷振子,也可以是压铸振子。辐射体的长度可以根据实际需要灵活设置。由于辐射体的长度与该辐射体的工作频段有关,因此,可以根据需要设计的半波振子的工作频段来确定辐射体的长度。该实 施例中,第一辐射臂10的两段辐射体的可以相同,也可以不同,第二辐射臂20的两段辐射体的可以相同,也可以不同。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.
本公开实施例中,第一辐射臂10与第二辐射臂20之间的夹角可以大于等于90度,且小于等于180度,例如,参见图1所示,第一辐射臂10与第二辐射臂20之间的夹角为180度(即第一辐射臂10和第二辐射臂20设置在一条直线上)。或者,参见图2所示,第一辐射臂10与第二辐射臂20之间的夹角为90度。又或者,参见图3所示,第一辐射臂10与第二辐射臂20之间的夹角为120度。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.
本公开实施例中,两个辐射臂中的连接器的状态可以不同,例如,第一连接器103将第一辐射体101与第二辐射体102连接,第二连接器203将第三辐射体201与第四辐射体202断开,此时,第一辐射臂10的工作频段为第一频段,第二辐射臂20的工作频段为第二频段。为了提高辐射效率,两个辐射臂中的连接器的状态可以相同,也就是说,第一辐射臂10的连接器(即第一连接器103)的状态与第二辐射臂20的连接器(即第二连接器203)的状态相同。例如,第一连接器103和第二连接器203可以均处于连接状态,此时,第一辐射体101与第二辐射体102连接,第三辐射体201与第四辐射体202连接,第一辐射臂10和第二辐射臂20的工作频段均为第一频段。或者,第一连接器103和第二连接器203可以均处于断开状态,此时,第一辐射体101与第二辐射体102处于断开状态,第三辐射体201与第四辐射体202处于断开状态,第一辐射臂10和第二辐射臂20的工作频段均为第二频段。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.
本公开实施例中,参见图4所示,连接器可以是开关,开关的两端分别与两段辐射体连接,根据需要发送或接收的信号的频段来控制开关的断开与连接,从而实现半波振子工作频段的切换。也就是说,第一开关103的一端与第一辐射体101连接,另一端与第二辐射体102连接。第二开关203的一端与第三辐射体201连接,另一端与第四辐射体202连接。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.
本公开实施例中,参见图5所示,连接器可以是电抗线,电抗线的两级分别连接辐射臂中的两段辐射体,第一电抗线103的一级与第一辐射体101连接,第一电抗线103的另一极与第二辐射体102连接,第二电抗线203的一级与第三辐射体201连接,第二电抗线203的另一极与第四辐射体202连接,电抗线的两级是否连接与输入电抗线的信号的频段有关。该实施例中,电抗线具备以下特性:在输入电抗线的信号的频率处于第一频段时,电抗线的两级处于连接状态,在输入电抗线的信号的频率处于第二频段时,电抗线的两级处于断开状态。也就是说,处于第一频段的信号可以在电抗线的两级之间进行传输,处于第二频段的信号无法在电抗线的两级进行传输。这样,对于第一辐射臂10,当输入第一辐 射臂10的信号处于第一频段时,信号可以通过第一电抗线103,从而在第一辐射体101与第二辐射体102之间传输,有效辐射体为第一辐射体101和第二辐射体102。当输入第一辐射臂10的信号处于第二频段时,信号无法通过第一电抗线,有效辐射体为第二辐射体102。对于第二辐射臂20,其工作原理参见第一辐射臂10的工作原理,此处不再赘述。采用电抗线作为连接器,不仅能够实现不同频段下的断开与连接,并且,由于电抗线两级的断开与连接与输入电抗线的信号的频率有关,因此,可以将处于第一频段和第二频段的信号同时输入至第一辐射臂10,处于第一频段的信号通过第一辐射体101和第二辐射体102进行传输,处于第二频段的信号通过第二辐射体102进行传输,从而实现同时覆盖两个频段。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.
本公开实施例中,电抗线可以是半钢性电缆,当然,还可以是其他材质。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.

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.

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.

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 .

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.

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.
