图 1为本发明实施例一提供的一种天线装置的示意图。 如图 1所示, 该 天线装置 1包括: 第一天线 10、 第二天线 11和功率调节器 12。  FIG. 1 is a schematic diagram of an antenna apparatus according to Embodiment 1 of the present invention. As shown in FIG. 1, the antenna device 1 includes: a first antenna 10, a second antenna 11, and a power conditioner 12.
具体的, 第一天线 10 用于在水平极化方向上辐射电磁波, 第二天线 11 用于在垂直极化方向上辐射电磁波。 天线的极化是指天线辐射时形成的 电场强度方向: 当电场强度方向平行于地面时, 此时天线的极化方向为水平 极化方向; 当电场强度方向垂直于地面时, 此时天线的极化方向为垂直极化 方向。  Specifically, the first antenna 10 is for radiating electromagnetic waves in a horizontal polarization direction, and the second antenna 11 is for radiating electromagnetic waves in a vertical polarization direction. The polarization of the antenna refers to the direction of the electric field strength formed when the antenna is radiated: when the direction of the electric field strength is parallel to the ground, the polarization direction of the antenna is the horizontal polarization direction; when the direction of the electric field strength is perpendicular to the ground, the antenna is The direction of polarization is the direction of vertical polarization.
进一步地, 功率调节器 12用于分别调节第一天线的功率和第二天线 的功率, 以使第一天线和第二天线的功率比值达到设定值。 Further, the power regulator 12 is configured to separately adjust the power of the first antenna and the second antenna The power is such that the power ratio of the first antenna and the second antenna reaches a set value.

The main antenna, such as a monopole antenna or a sleeve antenna. By using the first antenna 10 and the second antenna 11, vertical and horizontal coverage can be achieved, thereby achieving omnidirectional coverage of the antenna.
更进一步地, 功率调节器 12可以是由可调电容、 电感等器件构成的 电路。 通过功率调节器 12调节第一天线 10和第二天线 11的功率, 从而 改变第一天线 10和第二天线 11的方向图的覆盖范围。 在实际中, 可以根 据实际需求, 确定第一天线 10和第二天线 11的功率比值, 使得最终的天 线覆盖范围满足实际需求。举例来说,例如将天线装置 1应用于一栋塔(如, 埃菲尔铁塔) 时, 那么, 可以将第一天线 10 的功率调的相对大一些, 而 将第二天线 11 的功率调的相对小一些, 从而使该天线装置 1在垂直方向 上覆盖范围更大; 若实际需要用天线装置 1覆盖某一单层的仓库, 那么可 以将第二天线 11的功率调的相对大一些, 而将第一天线 11的功率调的相 对小一些, 从而使该天线装置 1在水平方向上覆盖范围更大。  Further, the power conditioner 12 may be a circuit composed of a device such as a tunable capacitor or an inductor. The power of the first antenna 10 and the second antenna 11 is adjusted by the power conditioner 12, thereby changing the coverage of the patterns of the first antenna 10 and the second antenna 11. In practice, the power ratio of the first antenna 10 and the second antenna 11 can be determined according to actual needs, so that the final antenna coverage satisfies the actual demand. For example, when the antenna device 1 is applied to a tower (e.g., the Eiffel Tower), then the power of the first antenna 10 can be relatively large, and the power of the second antenna 11 can be relatively small. Some, so that the antenna device 1 has a larger coverage in the vertical direction; if it is actually required to cover a single-layer warehouse with the antenna device 1, the power of the second antenna 11 can be adjusted to be relatively larger, and The power adjustment of an antenna 11 is relatively small, so that the antenna device 1 has a larger coverage in the horizontal direction.
需要说明的是, 这里并不限定功率调节器 12具体的内部器件及其连 接关系, 它可以通过调节第一天线 10和第二天线 11的自有阻抗来改变二 者的功率, 也可以通过为第一天线 10和第二天线 11外接可调电阻来改变 二者的功率。  It should be noted that the specific internal devices of the power conditioner 12 and their connection relationship are not limited herein. The power of the first antenna 10 and the second antenna 11 may be adjusted to change the power of the two antennas. The first antenna 10 and the second antenna 11 are externally connected with an adjustable resistor to change the power of both.
此外, 这里并不限制第一天线 10和第二天线 11的数量, 上述天线装 置 1中可以只包括一个第一天线 10和一个第二天线 11, 也可以包括多个 第一天线 10和多个第二天线 11, 当天线装置 1 中包括多个第一天线 10 和多个第二天线 11时,可以用功率调节器 12分别调节所有的第一天线 10 的总功率与所有的第二天线 11 的总功率, 使其达到预设比值, 从而达到 实际需要的天线覆盖范围。  In addition, the number of the first antenna 10 and the second antenna 11 is not limited herein. The antenna device 1 may include only one first antenna 10 and one second antenna 11, and may also include multiple first antennas 10 and multiple The second antenna 11 can adjust the total power of all the first antennas 10 and all the second antennas 11 respectively by the power conditioner 12 when the antenna device 1 includes the plurality of first antennas 10 and the plurality of second antennas 11 The total power is such that it reaches a preset ratio to achieve the actual required antenna coverage.

The second end of the inductor 213 is grounded, and the second end of the sixth inductor 214 is electrically connected to the signal source 22.
具体的, 可以通过上述天线装置 1中的功率调节器 12, 达到根据实际 需求改变天线装置 1的覆盖范围的目的。 第一匹配电路 20与第一天线 10 串联连接作为第一支路, 第二匹配电路 21与第二天线 11串联连接作为第 二支路, 信号源 22 的输出功率不变, 以保证并联的第一支路和第二支路 两端的电压相等, 根据电路原理可知, 此时第一支路与第二支路的功率与 其阻抗值成反比, 由于在实际中, 第一天线 10和第二天线 11的自有阻抗 是不变的, 因此, 可以通过调节第一匹配电路 20和第二匹配电路 21的阻 抗值, 使得第一天线 20和第二天线 21上的功率之比达到实际覆盖范围所 需要的比例。 举例来说, 实际需要用该天线装置 1在水平方向上覆盖 450 米, 在垂直方向上覆盖 50米, 即水平方向的覆盖范围与垂直方向的覆盖 范围之比为 9:1, 从前面的描述可知, 可以通过将第一天线 10和第二天线 11的功率比值调为 1:9, 达到上述的覆盖范围。 由于天线都有自有阻抗, 假设第一天线 10的自有阻抗为 50欧姆, 第二天线 11的自有阻抗也为 50 欧姆, 可以将第一匹配电路 20的阻抗调节为 160欧姆, 使得第一匹配电 路 20与第一天线 10串接组成的第一支路上的阻抗达到 210欧姆, 同时, 可以将第二匹配电路 21 的阻抗调节为 20欧姆, 使得第二匹配电路 21与 第二天线 11串接组成的第二支路上的阻抗达到 70欧姆,于是当信号源 22 的输出功率不变时, 由于第一支路与第二支路的阻抗之比为 3: 1, 因此, 流经上述两个支路的电流之比为 1 :3, 而第一天线 10和第二天线 11 的自 有阻抗相同, 因而第一天线 10和第二天线 11的功率分配比例即电流的平 方之比 1:9, 从而便通过调节功率调节器 12, 使得第一天线 10和第二天线 11 的功率分配比例达到 1:9, 从而实现上述垂直方向与水平方向呈 1 :9的 天线覆盖。当然,在实际中,即便调节上述两个支路的阻抗,使其达到 3: 1, 但由于在实际应用中, 还需考虑天线的传输系数, 因此, 可以根据第一天 线 10和第二天线 11的实际传输系数, 再对上述两个匹配电路进行微调, 使得第一天线 10和第二天线 11的功率分配比例达到 1 :9。 Specifically, the power conditioner 12 in the antenna device 1 described above can achieve the purpose of changing the coverage of the antenna device 1 according to actual needs. The first matching circuit 20 is connected in series with the first antenna 10 as a first branch, and the second matching circuit 21 and the second antenna 11 are connected in series as a second branch, and the output power of the signal source 22 is unchanged to ensure parallel connection. The voltages at both ends of a road and the second branch are equal. According to the circuit principle, the power of the first branch and the second branch is inversely proportional to the impedance value thereof, since in practice, the first antenna 10 and the second antenna The self-impedance of 11 is constant, and therefore, the resistance of the first matching circuit 20 and the second matching circuit 21 can be adjusted. The value of the resistance is such that the ratio of the power on the first antenna 20 and the second antenna 21 reaches the ratio required for the actual coverage. For example, the antenna device 1 is actually required to cover 450 meters in the horizontal direction and 50 meters in the vertical direction, that is, the ratio of the coverage in the horizontal direction to the coverage in the vertical direction is 9:1, from the foregoing description. It can be seen that the above coverage can be achieved by adjusting the power ratio of the first antenna 10 and the second antenna 11 to 1:9. Since the antenna has its own impedance, it is assumed that the self-impedance of the first antenna 10 is 50 ohms, and the self-impedance of the second antenna 11 is also 50 ohms, and the impedance of the first matching circuit 20 can be adjusted to 160 ohms, so that The impedance of the first branch formed by the matching circuit 20 and the first antenna 10 is 210 ohms, and the impedance of the second matching circuit 21 can be adjusted to 20 ohms, so that the second matching circuit 21 and the second antenna 11 The impedance of the second branch formed by the series connection reaches 70 ohms, so when the output power of the signal source 22 is constant, since the ratio of the impedance of the first branch to the second branch is 3:1, therefore, the above The ratio of the currents of the two branches is 1:3, and the self-impedances of the first antenna 10 and the second antenna 11 are the same, so the power distribution ratio of the first antenna 10 and the second antenna 11 is the ratio of the square of the current. :9, thereby adjusting the power conditioner 12 such that the power distribution ratio of the first antenna 10 and the second antenna 11 reaches 1:9, thereby achieving antenna coverage of 1:9 in the vertical direction and the horizontal direction. Of course, in practice, even if the impedance of the two branches is adjusted to 3: 1, since the transmission coefficient of the antenna needs to be considered in practical applications, the first antenna 10 and the second antenna may be used. The actual transmission coefficient of 11, the two matching circuits are fine-tuned so that the power distribution ratio of the first antenna 10 and the second antenna 11 reaches 1:9.
需要说明的是, 在实际中, 也可以把功率调节器 12作为天线的一部 分, 具体到图 2, 即将第一匹配电路 20作为第一天线 10的一部分, 将第 二匹配电路 21作为第二天线 11的一部分。 仍以上面的例子为例, 此时若 需要达到水平方向与垂直方向 1:9的覆盖范围,由于第一天线 10的阻抗为 其自有阻抗与第一匹配电路 20的阻抗值之和, 第二天线 11的阻抗为其自 有阻抗与第二匹配电路 21的阻抗之和, 因此, 只需第一天线 10的自有阻 抗加第一匹配电路 20的阻抗之和与第二天线 11的自有阻抗加第二匹配电 路 21的阻抗之和为 9: 1即可, 因此, 可以将第一匹配电路 20的阻抗调节 为 670欧姆, 使其与第一天线 10的阻抗之和为 720欧姆, 将第二匹配电 路 21的阻抗调节为 30欧姆, 使其与第二天线 20的阻抗之和为 80欧姆, 从而使得第一天线 10和第二天线 11的阻抗之比为 9:1, 因而其上的功率 之比为 1 :9, 从而达到水平方向与垂直方向 1 :9的覆盖范围。 It should be noted that, in practice, the power regulator 12 can also be used as a part of the antenna, specifically to FIG. 2, that is, the first matching circuit 20 is used as a part of the first antenna 10, and the second matching circuit 21 is used as the second antenna. Part of 11. Still taking the above example as an example, if it is required to reach a coverage of 1:9 in the horizontal direction and the vertical direction, since the impedance of the first antenna 10 is the sum of its own impedance and the impedance value of the first matching circuit 20, The impedance of the two antennas 11 is the sum of the impedance of the self-contained impedance and the impedance of the second matching circuit 21. Therefore, only the sum of the impedance of the first antenna 10 plus the impedance of the first matching circuit 20 and the self of the second antenna 11 are required. The sum of the impedances of the impedance-added second matching circuit 21 is 9:1. Therefore, the impedance of the first matching circuit 20 can be adjusted to 670 ohms so that the sum of the impedances of the first antenna 10 and the impedance of the first antenna 10 is 720 ohms. The impedance of the second matching circuit 21 is adjusted to 30 ohms so that the sum of the impedances of the second antenna 20 and the second antenna 20 is 80 ohms, so that the impedance ratio of the first antenna 10 and the second antenna 11 is 9:1, so that Power on The ratio is 1:9 to achieve a 1:9 coverage in the horizontal and vertical directions.
具体到实际器件, 上述第一匹配电路 20和第二匹配网络 21中的可调 电容可以通过矩阵式电容排布, 由多个小电容串联实现。  Specifically, to the actual device, the adjustable capacitors in the first matching circuit 20 and the second matching network 21 can be arranged in a matrix capacitor, and the plurality of small capacitors are connected in series.
由于第一天线 10和第二天线 11在单独使用时, 每个天线都有各自的 方向图, 而其各自的方向图都会有死角, 通过使用两个不同极化方向的天 线, 可以解决其各自的覆盖方向图有死角的问题, 从而实现天线的全向覆 盖。 并且, 由于存在功率调节器 12, 因而可以根据实际需要, 对第一天线 10和第二天线 11进行功率调节, 从而达到更符合实际条件的覆盖范围。  Since the first antenna 10 and the second antenna 11 are used alone, each antenna has its own pattern, and its respective patterns have dead angles. By using antennas with two different polarization directions, each of them can be solved. The coverage pattern has a problem of dead angles, thereby achieving omnidirectional coverage of the antenna. Moreover, since the power conditioner 12 is present, the first antenna 10 and the second antenna 11 can be power-adjusted according to actual needs, thereby achieving a coverage more in line with actual conditions.
