具体实施方式 Detailed ways

[0047] 为了使本技术领域的人员更好地理解本申请方案,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述。 [0047] In order to make those skilled in the art better understand the solutions of the present application, in conjunction with the following drawings of the present application example embodiments, the technical solutions in the embodiments of the present application will be described.

[0048] 实施例一: [0048] Example a:

[0049] 参见图1,该图为本申请实施例一提供的一种双极化天线隔离装置的结构示意图。 [0049] Referring to Figure 1, the picture shows a schematic structure of an application of the present dual-polarization antenna isolation apparatus according to a first embodiment. [0050]本实施例提供的双极化天线隔离装置包括:第一信号发射端101、第一信号接收端102和隔离单元103。 [0050] The present dual-polarization antenna isolation apparatus according to an embodiment comprises: a first signal transmitting terminal 101, receiving a first signal terminal 102 and the isolation unit 103.

[0051] 所述第一信号发射端101和所述第一信号接收端102位于相同的无线接入点中。 [0051] The first signal transmitter 101 and signal receiver of the first terminal 102 located in the same wireless access point. 所述无线接入点是用户接入无线核心网或以太网的桥梁,包括宏站、小站等。 The wireless access point is a wireless access to a core network or the user Ethernet bridge, including macro base stations, and other station. 所述第一信号发射端101和所述第一信号接收端102均可以为天线。 The first signal transmitting terminal 101 and receiving terminal 102 of the first signal that the antenna can be.

[0052]所述第一信号发射端1〇1用于在全双工模式下采用双极化天线发射信号,所述第一信号接收端1〇2用于在所述全双工模式下采用双极化天线接收信号。 [0052] The first signal transmitting terminal 1〇1 dual polarization antenna for transmitting signals in full duplex mode, said first signal receiving terminal 1〇2 for use in the full duplex mode dual polarized antenna reception signals. 如前文所述,所述全双工模式为所述第一信号发射端101发射的信号与所述第一信号接收端102接收的信号频率相同,且所述第一信号发射端101发射信号的时间与所述第一信号接收端102接收信号的时间相同。 As previously described, the full-duplex mode to the first transmit signal transmitted signal terminal 101 the same signal frequency received signal 102 to the first receiving terminal, and the first signal transmitting terminal 101 transmits the signal the first time and the signal receiving terminal 102 the same time as the received signal.

[0053]当所述第一信号发射端1〇1发射信号时,会产生向外辐射的电磁波,其中一部分电磁波的能量会流向所述第一信号接收端1〇2。 [0053] When the first signal transmitting terminal 1〇1 transmission signal, generates electromagnetic waves radiated outwardly, wherein a portion of the electromagnetic wave energy is flowing to the first signal receiving terminal 1〇2. 表现在方向图中,即为所述第一信号发射端的天线方向图的3dB波束宽度和所述第一信号接收端的天线方向图的3dB波束宽度在地面的覆盖范围发生部分或全部重合。 Performance in the direction in the figure, the receiving antenna is the end of the FIG signal transmitting end of the first antenna pattern and a 3dB beamwidth 3dB beamwidth of the first signal generating portion or all of the overlap of coverage of the ground. 所述天线方向图(radiation pattern),又叫福射方向图、 远场方向图等,是指在离天线一定距离处,辐射场的相对场强随方向变化的图形,通常采用通过天线最大辐射方向的两个相互垂直的平面方向图来表示,一个平面方向图为水平方向,另一个平面方向图为垂直方向。 The antenna pattern (radiation pattern), also known as Four shot pattern, far field pattern and the like, refers to a distance from the antenna, the relative change in direction of the radiation field with the field pattern, usually through an antenna of maximum radiation two mutually perpendicular directions in the plane of the pattern to represent a graph in the horizontal direction planar direction, the other planar direction vertical graph. 所述天线方向图的3dB波束宽度,也叫波束宽度,指的是主波瓣宽度。 The antenna pattern of 3dB beam width, the beam width is also called, referring to the main lobe width. 波瓣宽度,顾名思义,就是无线电波辐射形成的扇面所张开的角度。 Lobe width, by definition, is formed by a sector of the radio wave radiation opening angle. 同一天线发射的无线电波不同方向上的辐射强度是不同的,所以定义为比最大辐射方向上的功率下降3dB的两个方向之间的夹角为波瓣宽度。 Radiation intensity in different directions of the same antenna transmits the radio wave are different, it is defined as the angle between the two directions decrease 3dB power than the maximum radiation direction of the lobe width. 在水平面和垂直面各有一个波瓣宽度。 Have a beam width in horizontal and vertical planes. 天线方向图中能量密度最大方向上的波瓣称为主波瓣,主波瓣的宽度称为主波瓣宽度。 The antenna pattern lobes in the direction of maximum energy density is called a main lobe width of the main lobe called a main lobe width. 天线的波瓣宽度与其在地面的覆盖范围相关,波瓣宽度越大,辐射范围越广;波瓣宽度越小,辐射范围越小。 Lobe width of the antenna to its associated ground coverage, the greater the beam width, the wider the range of radiation; the smaller the beam width, the smaller the range of radiation.

[0054]当所述第一信号发射端的天线方向图的3dB波束宽度和所述第一信号接收端的天线方向图的3dB波束宽度在地面的覆盖范围全部或部分重合时,由于所述第一信号发射端101发射信号与所述第一信号接收端102接收信号是同时且同频的,因而,若所述第一信号发射端101向外辐射的电磁波被所述第一信号接收端102接收,就会对所述第一信号接收端102接收来自对端无线接入点的信号造成干扰。 [0054] When the antenna pattern of the antenna pattern of the transmitting end a first signal and a 3dB beam width of the first signal receiving end 3dB beamwidth coverage overlap all or part of the ground, since the first signal 101 transmit signals to the first signal transmitting terminal 102 receives a reception signal terminal simultaneously and in the same frequency, and thus, if the first signal transmitting end 101 of the electromagnetic waves are radiated outward end 102 receives a first received signal, it will receive signals from a wireless access point to the terminal for receiving the first signal interference caused by terminal 102.

[0055] 在本实施例中,我们将所述第一信号发射端101和所述第一信号接收端102均同时采用各自的双极化天线的两个极化方向工作时,由所述第一信号发射端101产生的电磁能量流向所述第一信号接收端102的路径称为能量耦合路径。 When [0055] In the present embodiment, we will first signal the first signal transmitting terminal and the receiving terminal 101 102 are two polarization directions while using a respective dual-polarized antenna operation, by the first an electromagnetic energy path signal transmitter 101 generates a signal flowing to the first receiving terminal 102 is referred to as energy coupling path. 所述电磁能量为电磁波的能量。 The electromagnetic wave energy is electromagnetic energy. [0056] 为了减小所述第一信号接收端102被所述第一信号发射端101辐射出来的电磁能量造成的干扰,本实施例在所述能量耦合路径上安置隔离单元103。 [0056] In order to reduce the first signal receiving terminal 102 is the interference caused by electromagnetic energy transmitting end a first signal out of radiation 101, the present embodiment is disposed on the isolating unit 103 coupled to the energy path. 所述隔离单元103可以位于所述能量耦合路径上的任意位置,用于阻断所述第一信号发射端101产生的电磁能量流向所述第一信号接收端102。 The isolation unit 103 may be located anywhere on the path of the energy coupling, for blocking the first end of the electromagnetic energy signal transmitter 101 generates a signal flowing to the first receiving terminal 102. 以图1为例,在该图中,所述第一信号发射端1〇1采用-45°方向的双极化天线发射信号,所述第一信号接收端102采用+45°方向的双极化天线接收信号。 1 as an example, in the figure, the first signal transmitting terminal 1〇1 -45 ° direction using polarized antenna transmit signals, the first received signal using bipolar + 45 ° direction end 102 of antenna reception signals. 虚线表示其中一条能量耦合路径,虚线的箭头表示电磁能量流动的方向。 Wherein the dotted line represents an energy coupling path, the broken line arrows indicate the direction of flow of electromagnetic energy. 在能量耦合路径上放置所述隔离单元103,以将从所述第一信号发射端101流向所述第一信号接收端102的电磁能量阻断,使得所述第一信号接收端102接收到的干扰信号减弱甚至消除。 Energy coupling path is placed on the spacer unit 103, to a first signal from the transmitter 101 of the first flow signal receiving terminal blocking electromagnetic energy 102, such that the first signal received by the receiving terminal 102 weaken or even eliminate the interference signal.

[0057]由于所述第一信号发射端101向四面八方辐射电磁波,因此所述能量耦合路径会有很多条。 [0057] Since the first signal transmitter 101 radiates electromagnetic waves in all directions, whereby said bars have a lot of energy coupling path. 理论上,为了最大限度的减少所述第一信号接收端102被所述电磁波造成的干扰,可以采用隔离单元103阻断所有的能量耦合路径,但是这样的话,所述隔离单元1〇3的面积会较大,成本会较高。 Theoretically, in order to reduce the maximum receiving the first signal interference caused by the electromagnetic wave 102 ends, the isolation unit 103 may be used to block all of the energy coupling path, but in this case, the area of ​​the cell isolation 1〇3 will be larger, the cost will be higher. 由于并不是每条能量耦合路径上的能量都相同,有些能量耦合路径上流动的电磁能量多些,有些能量耦合路径上流动的电磁能量少些。 Since not every energy on the energy coupling path are the same, some of the electromagnetic energy flows from the energy coupling path more, less electromagnetic energy flowing in a somewhat more energy coupling path. 为了节约所述隔离单元103的材料以及成本,可以选择仅在流动的电磁能量多的能量耦合路径上设置所述隔离单元103,例如,在电磁能量沿着所述第一信号发射端101的辐射边和所述第一信号接收端102的辐射边流向所述第一信号接收端102的能量耦合路径。 In order to save material and costs of the isolation unit 103 may select the isolation unit 103 is provided only on the flow of electromagnetic energy and more energy coupling path, e.g., electromagnetic radiation energy along the first signal transmitter 101 receiving a first signal edge and the end edge 102 of radiation toward said first signal path 102 coupled to the energy receiving end. 所述辐射边是指天线电磁能量脱离天线而向远处传播的边。 Refers to the side of the antenna radiation of electromagnetic energy from the antenna propagates to the distant side. 所述第一信号发射端101辐射边指向的方向是发射电磁能量最强的方向,所述第一信号接收端102的辐射边指向的方向是接收电磁能量最强的方向。 Direction of the first radiating edge 101 signal transmitter emits electromagnetic energy is directed in the direction of the strongest, signal radiation direction of the first receiving end 102 of the receiving side is directed in the direction of the strongest electromagnetic energy. [0058] 参见图2,该图为通过对所述第一信号发射端101和所述第一信号接收端102进行仿真得到的电磁能量示意图,其中,3端口为所述第一信号发射端101在-45°方向上的端口, 2端口为所述第一信号接收端102在+45°方向上的端口。 [0058] Referring to Figure 2, the graph obtained by a simulation of a schematic view of the electromagnetic energy of the first signal transmitter 101 and the first signal receiving terminal 102, which is a third port of the first signal transmitter 101 port in the -45 ° direction, to the second port of the first signal receiving terminal port 102 in the direction + 45 °. 所述3端口辐射边指向的方向为东南方向,所述2端口辐射边指向的方向为东北方向。 The 3-port side direction of radiation is directed southeast direction, the direction of the radiation side port 2 pointing northeast. 图2中颜色的深浅表示电磁能量的能量密度,颜色越浅表示能量密度越高,颜色越深表示能量密度越低,从该图中可以看出,在所述3端口附近,其辐射边指向的方向颜色较浅,能量密度较高,而其他方向颜色较深,能量密度较低;在2端口附近,其辐射边指向的方向颜色较浅,能量密度较高,其他方向颜色较深, 能量密度较低。 FIG 2 color depth represents the energy density of electromagnetic energy, lighter the color, the higher the energy density, the darker the color the lower the energy density, it can be seen from the figure, in the vicinity of the port 3, its radiation directed edges direction lighter color, a high energy density, and the other darker direction, a lower energy density; in the vicinity of the second port, the radiation direction side pointing lighter, high energy density, the darker the other direction, the energy low density. 从图2中可以看出,从3端口辐射边辐射的电磁能量有一部分沿着2端口的辐射边流向2端口,形成能量耦合路径。 As can be seen from Figure 2, the electromagnetic energy radiated from the radiation port 3 side port 2 flows along a part of the radiation port 2 side, form an energy coupling path. 为了将该能量耦合路径阻断,可以在该能量耦合路径上放置隔离单元EBG (Electromagnetic Band Gap,电磁带隙)结构。 The energy coupling path for blocking, isolating unit may be placed EBG (Electromagnetic Band Gap, EBG) structure on the energy coupling path. 所述EBG结构的具体位置可以仅在0A段上,也可以仅在0B段上,还可以同时跨0A段和0B段,其中,点0为所述3端口的辐射边与所述2端口的辐射边的交点,点A为3端口辐射边的起点,点B为2端口辐射边的终点。 The specific location may be on the EBG structure segment 0A, 0B section may be on, may also be simultaneously cross section merely 0A and 0B section, wherein the radiation point of 0 to 3 with the side port Port 2 radiating edge of the intersection point as a starting point a radiation port 3 side, the end point B of the second port of the radiating edge.

[0059] 参见图3,该图为在图2的基础上加入EBG结构后的电磁能量示意图,该EBG结构既跨0A段,又跨0B段,即该EBG结构在所述3端口的辐射边和所述2端口的辐射边相交的区域。 [0059] Referring to Figure 3, a schematic view of the electromagnetic energy is added to the graph after the EBG structure on the basis of FIG. 2, the EBG structure across both segments 0A, 0B and cross-section, i.e. in the EBG structure of the third port of the radiating edge 2 and the radiation port side intersecting region. 而且,从图3可以看出,所述EBG结构将电磁能量从3端口流向2端口的能量耦合路径阻断了, 2端口附近,尤其是辐射边的方向上的电磁能量大大降低(从浅色变为深色)。 Further, it can be seen from FIG. 3, the EBG structure of the electromagnetic energy flows from port 3 to port 2 energy coupling path is blocked, near the port 2, in particular in the direction of the radiation of electromagnetic energy side is greatly reduced (from light It goes dark).

[0060] 参见图4,该图为频率-隔离度对比图,该图中的x轴表示3端口发射信号的频率和所述2端口接收信号的频率;y轴表示隔离度,单位为dB,计算公式为10*log (V2/V3),V3是3 端口的电压,V2是2端口的电压。 [0060] Referring to Figure 4, the frequency graph - isolation comparison chart, x axis of the graph indicates frequency and the 3-port 2-port transmission signal received signals; Y axis represents the degree of isolation, in units of dB, calculated as 10 * log (V2 / V3), V3 is a voltage of 3 port, V2 is the voltage of the second port.

[0061] 图4中虚线表示所述图2中未加入所述EBG结构之前,3端口发射信号的频率或2端口接收信号的频率对应的隔离度;实线表示图3中加入所述EBG结构之后,3端口发射信号的频率或2端口接收信号的频率对应的隔离度。 [0061] FIG. 4 in dashed lines prior to the EBG structure 2 is not added, the frequency corresponding to the frequency of isolation of 3-port 2 transmission signal or a reception signal port of said graph; solid line indicates in FIG. 3 is added to the EBG structure then, the frequency corresponding to the frequency of isolation of the reception signal port or 3-port 2 transmission signal. 根据所述虚线和所述实线可以看出,在频率区间(2.480GHz,2.644GHz)内,所述隔离度在加入EBG结构之后显著下降,最低达到-47.50db, 证明在加入EBG结构后,所述2端口被所述3端口产生的电磁波干扰的程度有效降低。 According to the solid line and the broken line can be seen in the frequency interval (2.480GHz, 2.644GHz), a significant decrease in isolation after the addition of the EBG structure, to achieve the lowest -47.50db, demonstrated after adding the EBG structure, the second port is the degree of electromagnetic interference generated by the port 3 effectively reduced.

[0062] 在图2和图3中,所述第一信号发射端101在-45°方向上的端口(S卩3端口)发射信号,且所述第一信号接收端102在+45°方向上的端口(S卩2端口)接收信号。 [0062] In FIG 2 and FIG 3, the transmitting end a first signal port 101 in the -45 ° direction (S Jie port 3) transmit signal and the first signal receiving terminal 102 in the direction + 45 ° port on the (S Jie port 2) received signal. 由于所述第一信号发射端101和所述第一信号接收端102采用的是双极化天线,即所述第一信号发射端101 还在+45°方向上的端口发射信号,且所述第一信号接收端102在-45°方向上的端口接收信号,在这种情况下,图2和图3中的电磁能量分布以所述第一信号发射端101与所述第一信号接收端102的连线为轴相对称,能量耦合路径也以该轴相对称。 Since the signal of the first signal transmitting terminal and the first receiving terminal 101 is dual polarized antenna 102 employs, i.e., the first transmit signal on the transmit signal port 101 is also + 45 ° direction end, and the a first signal receiving terminal port 102 receives signals in the -45 ° direction, in this case, the electromagnetic energy in FIGS. 2 and 3 distributed in the first signal transmitting terminal and the receiving terminal 101 first signal wires 102 relative said axis, also the energy coupling path opposite said shaft. 参见图5,若图1为图3的简化版,那么图5即为在所述第一信号发射端101在+45°方向上的端口发射信号时形成的主要能量耦合路径,即以电磁能量从所述第一信号发射端101在+45°方向上的辐射边指向的方向, 流向所述第一信号接收端102在-45°方向上的辐射边指向的方向。 Referring to Figure 5, if 1 is a simplified version of FIG. 3, the main energy coupling path so formed in FIG. 5 is the transmit signal port of said first signal transmitting terminal 101 in the + 45 ° direction, i.e., electromagnetic energy direction of the radiation directed from the side end of the first signal transmitter 101 in the + 45 ° direction, the flow direction of the radiation directed sides of the first signal receiving terminal 102 in the direction of -45 °. 所述辐射单元103放置在所述第一信号发射端1〇1在+45°方向上的辐射边和所述第一信号接收端102在-45°方向上的辐射边相交的区域。 The radiating element 103 is placed on radiation transmitting end of the first radiating edge signal on 1〇1 + 45 ° direction and the first signal receiving terminal 102 in the -45 ° direction intersecting the edge region.

[0063] 参见图6(a),该图为两个2.6G的收发双极化天线安装在底板的实际效果图;参见图6(b),该图为在底板上加入隔离单元后的实际效果图,该图中的隔离结构指的是EBG结构。 [0063] Referring to FIG. 6 (a), the following illustration shows two transceivers 2.6G dual polarized antenna mounted on the bottom plate of FIG practical effect; see FIG. 6 (b), the actual picture shows the isolation unit is added on the bottom plate FIG effect, this figure refers to the isolation structure EBG structure.

[0064] 另外,上文提到的EBG结构为隔离单元103的一种实现方式。 [0064] Further, EBG structure mentioned above as the isolation unit 103 of one implementation. 所述EBG以前叫做光子带隙(Photonic Band Gap,PBG),是指由周期性结构组成的具有特定频段的电磁波产生阻带特性,在本实施例中用作电磁波的阻断或拦截。 The EBG formerly known as photonic bandgap (Photonic Band Gap, PBG), an electromagnetic wave having a specific frequency band refers to the periodic structure consisting of a stop-band generation, in the embodiment as an electromagnetic wave blocking or intercepting the present embodiment.

[0065] 所述隔离单兀103还可以是频率选择表面(Frequency Selective Surface,简称FSS),所述频率选择表面是由大量无源谐振单元组成的单屏或多屏周期性阵列结构,由周期性排列的金属贴片单元或在金属屏上周期性排列的孔径单元构成,具有反射电磁波的功能。 [0065] The spacer 103 may be a single Wu FSS (Frequency Selective Surface, referred to as the FSS), the frequency selective surface is a single screen or screen periodic array of structures of a large number of passive resonant units, by the period permutations metal patch unit or the metal aperture unit configuration screen periodically arranged, having an electromagnetic wave reflecting function.

[0066] 所述隔离单元103还可以是电磁吸收单元,即由电磁吸收材料构成,该吸波材料可以吸收投射到其表面的电磁波能量。 [0066] The isolation unit 103 may also be an electromagnetic absorbing unit, i.e., the absorbent material comprises a solenoid, the absorbing material can absorb electromagnetic energy projected onto the surface thereof. 按照吸波原理,所述吸波材料可以分为吸收型和干涉型,吸收型材料本身对电磁波进行吸收损耗,基本类型有复磁导率与复介电常数基本相等的吸收体、阻抗渐变“宽屏”吸收体和衰减表面电流的薄层吸收体;干涉型是利用吸波层表面的电磁波和底层振幅相等相位相反的反射波相抵消。 According to the principle of absorbing, absorbing materials can be divided into the absorption-type and interference-type, electromagnetic wave absorbing material for absorption loss itself, the basic types of complex permeability and complex permittivity substantially equal to the absorbent body, the impedance gradient " wide "absorbent sheet member and the surface current decay absorbent body; interference-type surface using an electromagnetic wave absorbing layer is equal to the amplitude of the reflected wave and the bottom of the opposite phase of the phase cancellation.

[0067] 可以理解的是,上述提到的三种类型的隔离单元103并不构成对本申请的限定,本领域技术人员还可以根据具体情况自行选择其他类型的隔离单元。 [0067] It will be appreciated that the isolation unit 103 of the three types mentioned above do not limit the present disclosure, one skilled in the art can also choose other types of self-isolation unit depending on the circumstances.

[0068] 所述隔离单元103的电磁能量隔离能力根据所述在预设频率范围内所述第一信号发射端的信号发射功率、在没有加入所述隔离单元的情况下所述第一信号接收端的实际信号接收功率、以及在加入所述隔离单元的情况下所述第一信号接收端的目标信号接收功率确定得到。 [0068] The electromagnetic energy isolated isolation unit 103 according to the transmit power of the signal within a predetermined frequency range of the first signal transmitting end, in the absence of the isolation unit is added to the first signal receiving end the actual power of the received signal, and the first signal receiving end with the addition of the isolation unit determines a target received power of the signal obtained. 本领域技术人员可以根据不同隔离能力的需求选择不同类型的隔离单元,若选择同一个隔离单元,可以依据所述隔离单元放置的不同位置、自身的大小、构造等来实现不同的隔离能力。 Those skilled in the art can choose different types of cells isolated according to the needs of different isolation if isolation unit select the same, can be based on different positions of the isolation unit is placed, its size, structure and the like to achieve different isolation. 如图3所述,所述EBG的小方块表示金属贴片,其和底板之间可以采用金属短路孔连接在一起,小方块越多隔离能力越强;小方块越少隔离能力越弱。 As shown in Figure 3, the small squares represent EBG metal patch, metal shorts between holes and the bottom plate may be used together, the more stronger small squares isolation capability; weaker fewer small blocks isolation. 此外,在图3中所述EBG位于所述同时跨0A段和0B段,其隔离能力要弱于其仅在0A段上,且高于其仅在0B段上, 因为0A段上的电磁能量强度高于0B段上的电磁能量强度。 Further, in FIG. 3 in the EBG positioned across both the segment 0A and 0B section, which is weaker than the isolation in which only segment 0A, and above which the electromagnetic energy in the 0A 0B section of only because higher strength than the strength of the electromagnetic energy 0B segment. 因而,所述隔离单元103具体在所述能量耦合路径放置的具体位置根据隔离能力确定,即放置在电磁能量满足预设能量条件的区域,所述预设能量条件可以例如是所述区域的平均电磁能量值在预设范围内,所述预设范围与隔离能力相匹配。 Thus, the isolation of the specific energy coupling path for locating the specific location of isolation means 103 determines, i.e., electromagnetic energy is placed in an area satisfying a predetermined energy condition, the preset condition may be, for example, the average energy of the region electromagnetic energy value within a predetermined range, the predetermined range to match with isolation. 以所述EBG结构为例,根据其隔离能力来设计EBG结构的金属贴片的尺寸、金属贴片之间的缝隙等参数,具体方法包括平面波展开法(PWE)、时域有限差分法(FDTD)、传输线矩阵法、积分方程法、有限元法等。 In the EBG structure, for example, according to its isolation sized metal patches EBG structure, a gap between the metal patches and other parameters, the method comprising specific plane wave expansion method (the PWE), finite difference time domain method (FDTD ), a transmission line matrix method, the integral equation method, the finite element method.

[0069] 此外,在本实施例中,所述双极化天线隔离装置还可以包括第二信号发射端和第二信号接收端,所述第二信号发射端用于在半双工模式下发射信号,所述第二信号接收端用于在所述半双工模式下接收信号,所述第二信号发射段和所述第二信号接收端位于所述无线接入点中。 [0069] Further, in the present embodiment, the dual-polarized antenna apparatus may further comprise a second isolating signal transmitting end and receiving end of a second signal, the second signal transmitting terminal for transmitting in half duplex mode signal, the second signal receiving terminal for receiving a signal in the half-duplex mode, transmitting said second signal segment and the second signal receiving terminal to said wireless access point. 所谓半双工模式即所述第二信号发射端和第二信号接收端在一个时间点只有其中一个在工作,即若所述第二信号发射端在向对端发射信号,则所述第二信号接收端暂停接收信号;若所述第二信号接收端在接收来自对端的信号,则所述第二信号发射端停止发射信号。 The so-called half duplex mode, i.e., the second signal transmitting terminal and a second terminal receiving only one signal at a time at the working point, i.e., if the second signal transmitting terminal to the remote end transmit signal, then the second pause signal receiving end receives a signal; a second signal if the received signal from the receiving end to end, then the second signal transmitter stops transmitting signals.

[0070]参见图7,该图为在图6的基础上,利用隔离单元103面积较小的优势,在底板剩余的空间中加入3 • 5GHz的天线和5 • 8GHz的天线,这两个天线的其中一个可以作为第二信号发射端,另外一个可以作为第二信号接收端。 [0070] Referring to Figure 7, the graph on the basis of FIG. 6, using the isolation unit 103 is small in size advantage, added 3 • 5GHz 5 • 8GHz antenna and an antenna in the remaining space in the bottom plate, the two antennas one can as a second signal terminal, the other as a second signal receiver. 也就是说,所述双极化天线隔离装置可以同时工作在2 • 6GHz的全双工和3 • 5GHz (未来TDD频段)和5 • 8GHz (WIFI频段)的半双工模式下。 That is, the dual-polarized antenna isolation device may operate in half-duplex mode and full duplex 2 • 6GHz 3 • 5GHz (future TDD frequency band) and 5 • 8GHz (WIFI band) simultaneously. 实现装置的功能多元化。 Diversification function realizing means.
