说 明 书  Description
一种增强型全向天线振子 技术领域  Enhanced omnidirectional antenna oscillator
本发明涉及电视信号接收天线领域, 更具体的说是一种具有全向、多频段信 号结构功能的增强型全向天线振子。  The present invention relates to the field of television signal receiving antennas, and more particularly to an enhanced omnidirectional antenna element having an omnidirectional, multi-band signal structure function.
背景技术  Background technique
天线是一种在无线电设备中用来发射或接收电磁波的部件。无线电通信、广 播、 电视、 雷达、 导航、 电子对抗、 遥感、 射电天文等工程系统, 凡是利用电磁 波来传递信息的, 都依靠天线来进行工作。 随着无线数字电视信号的普及, 越来 越多人在户外或移动中接收电视信号, 而不只局限于室内。在户外特别是移动中 接收电视信号, 因为信号塔是固定的, 而接收天线的位置会不断变化, 因此需要 使用全方位接收天线来保证较好的接收效果。  An antenna is a component used in a radio to transmit or receive electromagnetic waves. Engineering systems such as radiocommunication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy, etc., all use electromagnetic waves to transmit information, relying on antennas to work. With the spread of wireless digital television signals, more and more people are receiving television signals outdoors or on the move, not just indoors. Receiving TV signals outdoors, especially on the move, because the tower is fixed and the position of the receiving antenna is constantly changing, so a full range of receiving antennas is needed to ensure better reception.
现有技术公开了一种全方位电视接收天线,其包含三对呈 120度排列的半波 振子天线阵, 该天线阵通过 75欧同轴电缆线接入混合器中。 其中天线阵与同轴 电缆线的连接方式为: 用导线将两个振子的输出端连接至第三个振子的输出端, 再从该第三个振子的输出端用导线接入同轴电缆的正极或负极。  The prior art discloses an omnidirectional television receiving antenna comprising three pairs of half-wave antenna arrays arranged in a 120 degree arrangement, the antenna array being connected to the mixer through a 75 ohm coaxial cable. The antenna array and the coaxial cable are connected by: connecting the output ends of the two vibrators to the output end of the third vibrator by wires, and then connecting the coaxial cables from the output ends of the third vibrators Positive or negative.
现有技术还公开了一种电视接收天线, 其包含 U段折合振子, 该 U段振子由 三个完全相同并弯成 120度左右圆弧折合振子组成,并通过馈线与混合放大器相 连。 其中 U段三对振子的接线方式为: 三对弧形折合振子, 通过铜箔环并联, 再 与同轴电缆相连。  The prior art also discloses a television receiving antenna comprising a U-segmented vibrator consisting of three identically shaped arc-folded vibrators bent to about 120 degrees and connected to the hybrid amplifier via a feeder. The wiring mode of the three pairs of vibrators in the U section is as follows: Three pairs of arc-shaped folded vibrators are connected in parallel through the copper foil ring and then connected to the coaxial cable.
可见上述全方位天线的接线方式都需要使用到额外的导线, 接线复杂,且三 对振子是相互独立的振子, 需要配置混合器对信号进行混合处理。此外, 传统的 天线都是振子外露, 空气填充在振子之间对振子的阻抗造成影响, 在户外风速、 气压、 空气组成变化的环境下保证不了稳定的阻抗, 从而影响接收信号的质量。  It can be seen that the above-mentioned omnidirectional antenna wiring method requires the use of additional wires, the wiring is complicated, and the three pairs of vibrators are mutually independent vibrators, and the mixer needs to be configured to mix signals. In addition, the conventional antenna is exposed to the vibrator, and the air filling affects the impedance of the vibrator between the vibrators. In the environment where the outdoor wind speed, air pressure, and air composition change, stable impedance cannot be ensured, thereby affecting the quality of the received signal.
对于多个频段的接收天线, 为了避免信号之间的干扰, 不同频段的天线需要 进行空间上的隔离, 即需要保持一定的距离, 这就导致现有的天线无法制作得很 小。特别在安装空间有限的情况下, 比如在游艇或房车上使用, 可供安装的空间 十分有限, 为此只能牺牲部分频段的接收, 降低了使用者的用户体验。  For receiving antennas with multiple frequency bands, in order to avoid interference between signals, antennas in different frequency bands need to be spatially isolated, that is, need to maintain a certain distance, which results in the existing antenna cannot be made very small. Especially in the case of limited installation space, such as on a yacht or a motorhome, the space available for installation is very limited. To this end, only part of the frequency band can be sacrificed, which reduces the user experience.
发明内容 本发明所要解决的技术问题是克服现有缺陷, 提供一种具有全向、多频段信 号结构功能, 而且具有较小安装体积的增强型全向天线振子。 Summary of the invention The technical problem to be solved by the present invention is to overcome the existing drawbacks and provide an enhanced omnidirectional antenna element having an omnidirectional, multi-band signal structure function and having a small installation volume.
为实现上述发明目的, 本专利采用以下改良技术方案。  In order to achieve the above object, the patent adopts the following improved technical solutions.
本专利所改进的增强型全向天线振子, 包括至少两层上下叠加的全向振子, 所述全向振子包括环形均匀排列的多个振子,每个振子具有一个信号接收前端和 一个信号接收后端, 引线连接振子信号接收后端引出信号, 每个振子与其所对应 的引线构成振子单元,每层全向振子中的振子的信号接收后端与相邻层全向振子 中的振子的信号接收后端相互错开。由环形排列的振子构成的全向振子能够接收 各个方向的信号, 无需对信号角度进行校准, 特别是在移动的平台上使用十分方 便。通过将全向振子多层叠加, 一方面能够增强信号接收, 一方面可以设置不同 大小的全向振子用于接收不同频段的信号。进一步的, 通过层叠的安装结构, 能 够将整个振子安装在很小的空间内。  The enhanced omnidirectional antenna element improved by the patent comprises at least two layers of omnidirectional vibrators superimposed on top of each other, the omnidirectional vibrator comprising a plurality of vibrators arranged in a ring shape, each vibrator having a signal receiving front end and a signal receiving The lead-connected vibrator signal receives the rear-end pull-out signal, and each vibrator and its corresponding lead form a vibrator unit, and the signal receiving back end of the vibrator in each layer of the omnidirectional vibrator and the signal receiving of the vibrator in the adjacent layer omnidirectional vibrator The back ends are staggered from each other. The omnidirectional vibrator consisting of ring-shaped vibrators can receive signals in all directions without the need to calibrate the signal angle, especially on mobile platforms. By superimposing the omnidirectional oscillators in multiple layers, on the one hand, signal reception can be enhanced, and on the other hand, omnidirectional oscillators of different sizes can be set for receiving signals of different frequency bands. Further, the entire vibrator can be installed in a small space by the laminated mounting structure.
上述多层全向振子安装在一个较小的空间内,为避免层与层之间的全向振子 的信号相互影响, 需要对其具体安装结构做进一步的调整。 根据信号接收理论, 每个振子的信号接收前端的信号强度最弱, 信号接收后端的信号强度最强, 因此 本专利将每层全向振子中的振子的信号接收后端与相邻层全向振子中的振子的 信号接收后端相互错开, 这样就避免了层与层之间, 信号最强的部分靠得太近而 带来的信号干扰, 保证了信号接收的质量。  The above-mentioned multilayer omnidirectional oscillator is installed in a small space. In order to avoid the mutual influence of the signals of the omnidirectional oscillator between the layers, further adjustment of the specific mounting structure is required. According to the signal reception theory, the signal strength of the signal receiving front end of each vibrator is the weakest, and the signal intensity of the signal receiving back end is the strongest. Therefore, in this patent, the signal receiving end of the vibrator in each layer of the omnidirectional oscillator is omnidirectional and adjacent to the omnidirectional layer. The signal receiving end of the vibrator in the vibrator is staggered from each other, thus avoiding signal interference between the layers and the strongest part of the signal, so as to ensure the quality of signal reception.
为了最大程度的避免相邻层全向振子接收信号的相互影响,每层全向振子中 的振子的信号接收后端与相邻层全向振子中的振子的信号接收后端在周向上最 大角度相互错开。 由于本专利采用多层振子平行布置的方式, 所以在周向上提供 了很大的隔离空间。另外由于每层全向振子都均匀设有多个振子, 因此通过周向 的角度错开振子的信号接收后端能够使其之间距离最长,相互之间的干扰下降到 最低。  In order to minimize the mutual influence of the signals received by the adjacent omnidirectional oscillators, the signal receiving back end of the vibrator in each omnidirectional vibrator and the signal receiving back end of the vibrator in the adjacent layer omnidirectional oscillator have a maximum angle in the circumferential direction. Staggered from each other. Since this patent uses a multi-layer vibrator arranged in parallel, it provides a large isolation space in the circumferential direction. In addition, since each of the omnidirectional vibrators is uniformly provided with a plurality of vibrators, the signal receiving end of the vibrator is shifted by the circumferential angle to maximize the distance between them, and the interference between them is minimized.
为了方便相邻层的振子的信号接收后端的错开布置,每层全向振子包括偶数 个振子, 两两相邻振子的信号接收后端或前端相对, 每层全向振子中的振子两两 相对的信号接收后端与相邻层全向振子中的振子两两相对的信号接收前端在同 一方向上 ± 2cm的区间内。 将两两相邻振子的信号接收后端或前端相对, 组成多 对振子, 使得每层全向振子上的信号接收后端成对出现, 即信号最强端在全向振 子的周向上分布的距离增加一倍。即相邻层的振子的信号接收后端的错开的角度 可以增加一倍以上, 进一步降低相邻层之间的信号干扰。在本专利中每层全向振 子中的振子两两相对的信号接收后端与相邻层全向振子中的振子两两相对的信 号接收前端在同一方向上 ± 2cm的区间内, 理论上在同一方向上时, 相邻层的信 号强度最大处的距离最大, 但在实际制作中, 存在工程误差, 因此在实际制作的 时候, 根据具体的工程调整, 一般控制在同一方向左右 2cm的工程误差内。 In order to facilitate the staggered arrangement of the signal receiving back end of the vibrator of the adjacent layer, each omnidirectional vibrator includes an even number of vibrators, and the signal receiving back end or front end of the two adjacent vibrators is opposite, and the vibrators in each omnidirectional vibrator are opposite each other. The signal receiving front end and the signal receiving front end opposite to each other in the adjacent layer omnidirectional oscillator are within a range of ± 2 cm in the same direction. The signals of the two adjacent vibrators are opposite to each other and form a plurality of pairs of vibrators, so that the signal receiving back ends of each layer of the omnidirectional oscillators appear in pairs, that is, the strongest end of the signal is distributed in the circumferential direction of the omnidirectional oscillator. The distance has doubled. That is, the signal of the adjacent layer of the vibrator receives the staggered angle of the rear end It can be more than doubled to further reduce signal interference between adjacent layers. In the present patent, the signal receiving front end of the vibrator in each layer of the omnidirectional vibrator is opposite to the signal receiving front end of the vibrator in the adjacent layer omnidirectional oscillator in the same direction ± 2 cm, theoretically In the same direction, the distance between the signal intensity of the adjacent layer is the largest, but in the actual production, there is engineering error. Therefore, in actual production, according to the specific engineering adjustment, the engineering error of 2cm in the same direction is generally controlled. Inside.
根据信号的干扰原理, 低频信号对高频信号的影响明显, 反之, 高频信号对 低频信号的影响却不大, 对于接收不同频段信号的多个全向振子, 相邻的振子之 间的频段不应差距太大, 以防止低频段的信号干扰高频段的信号接收。 因此本专 利的全向振子采用直径由下自上递减的叠加方式, 不仅可以减少信号干扰, 而且 提高了结构稳定性。另外引线上的信号强度很大, 本专利将引线设置在相应全向 振子同一平面上, 一端连接振子信号接收后端, 另一端汇集至振子中心, 使振子 单元呈星型排列,将引线平铺的方式大大减少了各层之间引线上信号的相互干扰。  According to the principle of interference of signals, the influence of low-frequency signals on high-frequency signals is obvious. On the contrary, the influence of high-frequency signals on low-frequency signals is not large. For multiple omnidirectional oscillators receiving signals of different frequency bands, the frequency bands between adjacent oscillators The gap should not be too large to prevent signals in the low frequency band from interfering with signal reception in the high frequency band. Therefore, the patented omnidirectional oscillator adopts a superposition method in which the diameter is reduced from the bottom to the bottom, which not only reduces signal interference but also improves structural stability. In addition, the signal strength on the lead wire is very large. In this patent, the lead wire is disposed on the same plane of the corresponding omnidirectional vibrator, one end is connected to the vibrator signal receiving rear end, and the other end is collected to the vibrator center, so that the vibrator unit is arranged in a star shape, and the lead wire is tiled. The way to greatly reduce the mutual interference of the signals on the leads between the layers.
对于电视信号来说, 一般包括高频段信号和低频段信号, 高频段的频率在 470Hz 862Hz之间, 中心频率为 650Hz, 低频段的频率在 47Hz 230Hz之间, 中心 频率为 200Hz。 针对这两种全球通用的频段, 本专利包括上、 下两层全向振子, 每层全向振子包括偶数个振子, 两两振子的信号接收后端或前端相对, 即两两振 子单元的引线相邻排列, 构成星型排列的振子对。  For TV signals, high frequency signals and low frequency signals are generally included. The high frequency band is between 470 Hz and 862 Hz, the center frequency is 650 Hz, the low frequency band is between 47 Hz and 230 Hz, and the center frequency is 200 Hz. For these two global frequency bands, this patent includes two layers of upper and lower omnidirectional oscillators. Each layer of omnidirectional oscillators includes an even number of vibrators. The signal receiving ends of the two vibrators are opposite to each other, that is, the leads of the two vibrator units. Arranged adjacent to each other to form a pair of oscillators arranged in a star shape.
为了提高全向的接收能力, 尽量做到信号在每个方向上的接收无差异化, 本 专利所述多个振子在每个全向振子平面上呈圆环形排列, 所述振子呈弧形, 引线 呈直线型连接, 连接振子的信号接收后端至全向天线振子中心。这种结构使得信 号无论从那个方向过来, 均能够实现接收的均匀化, 而且圆形结构无需区分安装 方向, 更方便安装, 安装后的外形呈圆形, 大大减少了体积。  In order to improve the omnidirectional receiving capability, the signal is not differentiated in each direction as much as possible. The plurality of vibrators described in this patent are arranged in a circular shape on each omni vibrator plane, and the vibrator is curved. The lead wire is connected in a straight line, and the signal connecting the vibrator receives the back end to the center of the omnidirectional antenna element. This structure enables the signal to be uniformized in reception from that direction, and the circular structure does not need to distinguish the mounting direction, which is more convenient to install, and the shape after installation is circular, which greatly reduces the volume.
具体的结构是每层全向振子包括 6 个振子, 设置两层, 上层振子长度在 l(Tl4cm之间, 用于接收 470Η 862ΗΖ的高频段信号, 下层振子长度在 38 42cm 之间, 用于接收 47Η 230ΗΖ的低频段信号, 每层全向振子上两两振子的信号接 收后端或前端相对, 引线相邻排列, 构成呈星型排列的 3对振子对, 每对振子对 相邻 120 ° 排列。 即每对振子比邻的引线同样呈 120 ° 排列, 考虑到工程误差, 上下层之间每对引线的角度差为 60 ° 左右。  The specific structure is that each layer of omnidirectional oscillator includes 6 vibrators, and two layers are provided. The length of the upper vibrator is between 1 (Tl4cm, for receiving the high frequency band signal of 470Η 862ΗΖ, and the length of the lower vibrator is 38 42cm, for receiving. 47Η 230ΗΖ low-band signal, the signal receiving end or front end of each two-layer vibrator on each layer is opposite, and the leads are arranged adjacent to each other to form three pairs of vibrator pairs arranged in a star shape. Each pair of vibrators is arranged adjacent to 120 °. That is, the leads of each pair of vibrators are also arranged at 120 °. Considering the engineering error, the angle difference between each pair of leads between the upper and lower layers is about 60 °.
上述全向振子中的至少一个全向振子包括支撑盘、分别设置在支撑盘上下面 的两个振子片; 所述振子片包括中心的接线埠、 从接线埠向外均布辐射的引线, 引线末端连接振子的信号接收后端; 两个振子片上的振子周向相互错开, 支撑盘 上下相邻的两个振子构成振子对。接线埠直接作为振子片的一个部分, 无需额外 的导线来连接, 简化了接线操作并避免了导线损坏等带来的风险。两个振子片上 的振子周向相互错开,其意思是两个振子片的振子在支撑盘的同一位置的正反面 上不重合, 以免产生干扰。 具体的结构是所述振子片包括三个振子, 呈 120 ° 排 列,上下两个振子片构成呈星型排列的 3对振子对,每对振子对相邻 120 ° 排列。 两个振子片的振子一一对应, 形成多对功能上的振子对, 三对振子对的信号汇集 到接线埠通过同轴电缆输出, 无需额外设置混合器对信号进行混合, 简化了天线 组件的配置。 上述支撑盘选用非金属材质, 优选塑料材质, 两个振子片紧贴于支 撑盘的上下面, 起到优秀的信号屏蔽作用。另外通过调节支撑盘的厚度能够灵活 调整整个全向振子的阻抗, 以便于与信号线匹配。 The at least one omnidirectional vibrator of the omnidirectional vibrator includes a support disc, two vibrating pieces respectively disposed on the lower surface of the support disc; the vibrator piece includes a central connecting cymbal, and a lead wire uniformly radiated from the connecting cymbal, The end of the lead is connected to the signal receiving end of the vibrator; the vibrators on the two vibrating pieces are circumferentially offset from each other, and the two vibrators adjacent to the upper and lower sides of the supporting disc constitute a pair of vibrators. The wiring 埠 directly acts as a part of the vibrator piece, eliminating the need for additional wires to connect, simplifying the wiring operation and avoiding the risk of wire damage. The vibrators on the two vibrator pieces are circumferentially offset from each other, which means that the vibrators of the two vibrator pieces do not overlap on the front and back surfaces of the same position of the support disc to avoid interference. The specific structure is that the vibrator piece includes three vibrators arranged at 120 °, and the upper and lower vibrator pieces form three pairs of vibrator pairs arranged in a star shape, and each pair of vibrators is arranged adjacent to 120 °. The vibrators of the two vibrator pieces are in one-to-one correspondence, forming pairs of functional vibrator pairs. The signals of the three pairs of vibrator pairs are collected into the wiring port and output through the coaxial cable, and the mixer is not required to be additionally mixed to simplify the antenna assembly. Configuration. The support plate is made of a non-metal material, preferably a plastic material, and the two vibrator pieces are closely attached to the upper and lower sides of the support plate to provide excellent signal shielding. In addition, the impedance of the entire omnidirectional oscillator can be flexibly adjusted by adjusting the thickness of the support disk to facilitate matching with the signal line.
对于低频的全向振子, 其每个振子的弧长较长, 比如用于接收 47Η 230ΗΖ 的低频段信号的振子弧长达到 38 42cm, 为了减少天线的体积, 本专利中至少一 个全向振子上的振子的信号接收前端沿直径方向向内弯折,或者是至少一个全向 振子上的振子的信号接收前端沿直径方向向内弯折后, 沿周向再次弯折, 这样便 能够大大减小天线的体积, 而且弯折的部分是振子的信号接收前端, 信号较弱, 弯折所带来对信号接收的影响较小, 保证信号接收质量。  For low-frequency omnidirectional oscillators, each of the vibrators has a long arc length, such as an oscillator arc length of 38 42 cm for receiving a low-band signal of 47 Η 230 ,. In order to reduce the size of the antenna, at least one omnidirectional oscillator in this patent The signal receiving front end of the vibrator is bent inward in the diametrical direction, or the signal receiving front end of the vibrator on the at least one omnidirectional vibrator is bent inward in the diameter direction, and is bent again in the circumferential direction, so that the signal can be greatly reduced. The volume of the antenna, and the bent part is the signal receiving front end of the vibrator, the signal is weak, and the impact of the bending on the signal receiving is small, and the signal receiving quality is ensured.
综上所述, 本发明通过层叠全向振子的结构, 并将相邻的全向振子的信号强 部错开布置,这种结构在保证信号接收质量和最大程度降低各个频段信号干扰的 情况下, 将整个天线的体积降到最小。相对于现有的多频段的电视天线结构, 本 专利的体积大大减小, 且具有无方向差异的信号接收效果, 特别适用户外移动的 平台上使用, 如游艇或房车等经常跨不同信号区域的交通工具。  In summary, the present invention lays out the structure of the omnidirectional vibrator and displaces the signal strong portions of adjacent omnidirectional vibrators. This structure ensures signal reception quality and minimizes signal interference in each frequency band. Minimize the size of the entire antenna. Compared with the existing multi-band TV antenna structure, the patent has a greatly reduced volume and has a signal receiving effect with no difference in direction, and is particularly suitable for use on an outdoor mobile platform, such as a yacht or a motorhome, which often crosses different signal regions. Transportation.

实施例 1  Example 1
如图 1所示的一种全向天线,包括天线外壳 1和设置于天线外壳 1下方的支 座 4, 支座 4居中设置, 在天线外壳 1下方一侧设有接线头 5。 所述天线外壳 1 整体呈圆盘形, 内安装有全向天线振子, 从外形上可以看出, 整个天线外壳 1的 高度很小, 结构十分紧凑。 因此通过设置在天线外壳 1下方中心的支座 4, 能够 起到稳定的完全支撑, 防止在使用过程中所带来的震动, 如在车或船等移动交通 工具上使用。整体体积的减小, 一方面节省空间, 能够在安装空间有限的平台上 安装, 如房车或游艇; 另一方面有利于提高稳定性, 防止在户外使用时, 外界环 境所带来的震动或偏移, 如抗风和抗震能力的提高, 由此所带来的信号接收的稳 定性提升, 提高用户体验。  An omnidirectional antenna as shown in Fig. 1 includes an antenna housing 1 and a support 4 disposed below the antenna housing 1. The holder 4 is centrally disposed, and a terminal 5 is disposed on the lower side of the antenna housing 1. The antenna housing 1 has a disk shape as a whole, and an omnidirectional antenna element is mounted therein. As can be seen from the outer shape, the entire antenna housing 1 has a small height and a compact structure. Therefore, the support 4 provided at the center below the antenna casing 1 can provide stable and complete support to prevent vibrations during use, such as on a mobile vehicle such as a car or a ship. The overall volume is reduced, on the one hand, it saves space, and can be installed on a platform with limited installation space, such as a motorhome or a yacht; on the other hand, it helps to improve stability and prevent vibration or partiality caused by the external environment when used outdoors. The movement, such as the improvement of wind resistance and seismic resistance, enhances the stability of signal reception and improves the user experience.
从图 2可以进一步了解上述全向天线的内部结构, 如图所示, 所述天线外壳 1由上下壳体 11、 12相对拼接构成,壳体内由上而下依次安装有上层全向振子 2、 下层全向振子 3、电路板 6和导线板 7。下壳体 12起到支撑上述内部结构的作用, 上壳体 11起到密封和保护的作用。 上层全向振子 2和下层全向振子 3电连接至 电路板 6, 电路板 6上的电线 (图中未示出) 穿过导线板 7连接至接线头 5。 进 一步如图 3和图 4所示, 所述上层全向振子 2和下层全向振子 3同样呈圆形, 上 下同心设置, 两个振子面相互平行。  The internal structure of the above omnidirectional antenna can be further understood from FIG. 2. As shown, the antenna housing 1 is formed by splicing of the upper and lower housings 11, 12, and the upper omnidirectional vibrator 2 is installed in the housing from top to bottom. The lower omnidirectional vibrator 3, the circuit board 6 and the wiring board 7. The lower casing 12 functions to support the above internal structure, and the upper casing 11 functions as a seal and protector. The upper omnidirectional vibrator 2 and the lower omnidirectional vibrator 3 are electrically connected to the circuit board 6, and the wires (not shown) on the circuit board 6 are connected to the wiring head 5 through the wiring board 7. Further, as shown in Fig. 3 and Fig. 4, the upper omnidirectional vibrator 2 and the lower omnidirectional vibrator 3 are also circular, and are arranged concentrically, and the two vibrator faces are parallel to each other.
下层全向振子 3如图 5所示, 下层全向振子 3包括六个振子单元, 振子单元 分别由振子 31、 32、 33、 34、 35和 36 以及引线 311、 321、 331、 341、 351和 361构成, 振子 31、 32、 33、 34、 35和 36呈弧形, 引线 311、 321、 331、 341、 351和 361呈直线型。 六个振子单元在全向振子平面上呈圆环形排列, 两两相对 构成三对呈星型排列的振子对, 每对振子对相邻 120 ° 排列。 如图 6所示, 以振 子 31和 32构成的振子对为例, 振子 31、 32各具有一个信号接收前端 312、 322 和一个信号接收后端 313、323,引线 311、321分别连接振子的信号接收后端 313、 323至下层全向振子 3中心, 引出信号。 所述振子 31、 32的信号接收前端 312、 322至信号接收后端 313、 323的长度为 40cm, 匹配 47Hz〜230Hz的低频段信号, 由于振子的长度太长, 安装后占用体积过大, 因此在本实施例中将信号接收前端 312、 322沿直径方向向内弯折, 这样安装后的体积大大减小。 The lower omni vibrator 3 is as shown in FIG. 5, and the lower omni vibrator 3 includes six vibrator units, and the vibrator unit is composed of vibrators 31, 32, 33, 34, 35 and 36 and leads 311, 321, 331, 341, 351 and The 361 is constructed such that the vibrators 31, 32, 33, 34, 35, and 36 are curved, and the leads 311, 321, 331, 341, 351, and 361 are linear. The six vibrator units are arranged in a circular shape on the plane of the omnidirectional oscillator, and the two pairs are opposite to form three pairs of vibrator pairs arranged in a star shape, and each pair of vibrators is arranged adjacent to 120 °. As shown in FIG. 6, the vibrator pair consisting of the vibrators 31 and 32 is exemplified, and the vibrators 31 and 32 each have a signal receiving front end 312, 322 and a signal receiving rear end 313, 323, and the leads 311, 321 respectively connect the signals of the vibrator. The back ends 313, 323 are received to the center of the lower omnidirectional vibrator 3 to extract signals. The signal receiving front ends 312, 322 of the vibrators 31, 32 to the signal receiving back ends 313, 323 have a length of 40 cm, and match the low frequency band signals of 47 Hz to 230 Hz. Since the length of the vibrator is too long, the occupied volume after installation is too large. In the present embodiment, the signal receiving front ends 312, 322 are bent inward in the diametrical direction, so that the volume after mounting is greatly reduced.
上层全向振子 2如图 12所示, 上层全向振子 2包括支撑盘 201、 分别设 置在支撑盘 201上下面的上层振子片 202和下层振子片 203, 如图 7所示。 如图 8和 9所示, 所述上层和下层振子片 202和 203包括中心的接线埠 204和 205、 从接线埠 204和 205向外均布辐射的引线 211、 231、 251和 221、 241、 261, 引 线 211、 231、 251和 221、 241、 261末端分别连接振子 21、 23、 25和 22、 24、 26。所述上层振子片 202和下层振子片 203上的弧形振子 21、 23、 25和 22、 24、 26周向相互错开, 如图 10所示。 支撑盘 201上下相邻的两个振子 21和 22、 23 和 24、 25和 26构成三对呈星型排列的振子对, 每对振子对相邻 120 ° 排列, 如 图 11所示。 如图 12所示, 以振子 21和 22构成的振子对为例, 振子 21、 22各 具有一个信号接收前端 212、 222和一个信号接收后端 213、 223, 引线 211、 221 分别连接振子的信号接收后端 213、 223至上层全向振子 2中心的接线埠 204、 205, 引出信号。  The upper omnidirectional vibrator 2 is as shown in Fig. 12. The upper omnidirectional vibrator 2 includes a support disk 201, an upper layer vibrator piece 202 and a lower layer vibrator piece 203 which are respectively disposed on the upper and lower sides of the support disk 201, as shown in Fig. 7. As shown in Figures 8 and 9, the upper and lower vibrator pieces 202 and 203 include central wiring ports 204 and 205, and leads 211, 231, 251, and 221, 241 that are radiated outwardly from the wiring ports 204 and 205. 261, the ends of the leads 211, 231, 251 and 221, 241, 261 are connected to the vibrators 21, 23, 25 and 22, 24, 26, respectively. The arcuate vibrators 21, 23, 25 and 22, 24, 26 on the upper vibrator piece 202 and the lower vibrator piece 203 are circumferentially offset from each other as shown in FIG. The two vibrators 21 and 22, 23 and 24, 25 and 26 adjacent to each other on the support disc 201 constitute three pairs of vibrator pairs arranged in a star shape, and each pair of vibrators are arranged adjacent to each other at 120 ° as shown in FIG. As shown in FIG. 12, the vibrator pair composed of the vibrators 21 and 22 is exemplified, and the vibrators 21 and 22 each have a signal receiving front end 212, 222 and a signal receiving rear end 213, 223, and the leads 211 and 221 respectively connect the signals of the vibrator. The terminals 213, 223 are received from the back ends 213, 223 to the terminals 204, 205 at the center of the upper omnidirectional vibrator 2 to extract signals.
支撑盘 201上设有凹槽,上层和下层振子片 202和 203部分或全部嵌入凹槽 中。 由于上层和下层振子片 202和 203安装在支撑盘 201上, 可以通过调整凹槽 的形状、 宽度、 厚度等, 来调节上层和下层振子片 202和 203之间的绝缘距离, 以达到调节天线的阻抗的目的。 优选地, 当支撑盘的厚度为 1 mm时, 支撑盘上 设置有凹槽处的厚度为 0. 5mm, 调节凹槽形状后天线的阻抗为 75欧姆。 另外, 上层和下层振子片 202和 203的接线埠 204和 205上设有接线柱, 下层振子片 203的接线柱穿过支撑盘 201的接线孔与同轴线缆 (图中未示出)相连, 通过接 线柱将两个接线埠 204和 205的输出端引至支撑盘 201的同一侧,从而方便了与 同轴线缆的连接。 所述振子 21、 22 的信号接收前端 212、 222至信号接收后端 213、 223的长度为 12cm, 匹配 470Hz〜862Hz的高频段信号。 The support disk 201 is provided with a groove, and the upper and lower vibrator pieces 202 and 203 are partially or entirely embedded in the groove. Since the upper and lower vibrator pieces 202 and 203 are mounted on the support disk 201, the insulation distance between the upper and lower vibrator pieces 202 and 203 can be adjusted by adjusting the shape, width, thickness, etc. of the groove to adjust the antenna. The purpose of the impedance. 5毫米之间。 The thickness of the support disk is 0. 5mm, the impedance of the antenna after the groove shape is adjusted to 75 ohms. In addition, the terminals 205 and 205 of the upper and lower vibrating pieces 202 and 203 are provided with binding posts, and the terminals of the lower vibrating piece 203 are connected to the coaxial cable (not shown) through the wiring holes of the supporting plate 201. The output ends of the two wiring ports 204 and 205 are led to the same side of the support plate 201 through the binding posts, thereby facilitating the connection with the coaxial cable. Signal receiving front ends 212, 222 of the vibrators 21, 22 to the signal receiving back end 213, 223 has a length of 12cm and matches a high frequency band signal of 470 Hz to 862 Hz.
根据信号的干扰原理, 低频信号对高频信号的影响明显, 反之, 高频信号对 低频信号的影响却不大, 对于上述接收不同频段信号的两个全向振子 2和 3, 采 用直径由下自上递减的叠加方式, 不仅可以减少信号干扰, 而且提高了结构稳定 性。另外由于信号接收末端的信号强度最大, 在叠加时应尽量避免上下层振子之 间信号最强的部位过于靠近,因此所述上层和下层全向振子 2和 3中的振子的信 号接收后端与相邻层全向振子中的振子的信号接收后端在周向上相互错开。理论 上当上层全向振子 2的信号接收末端与下层全向振子 3的信号接收前端在同一方 向上时,相邻层的信号强度最大处的距离最大,但在实际制作中,存在工程误差, 因此在实际制作的时候, 根据具体的工程调整, 一般控制在同一方向左右 2cm的 工程误差内, 如图中所示。 如图 13中的所示的上层全向振子 2的信号接收后端 213、 223和下层全向振子 312、 362错开一定角度 a。  According to the principle of interference of signals, the influence of low-frequency signals on high-frequency signals is obvious. On the contrary, the influence of high-frequency signals on low-frequency signals is not large. For the above two omnidirectional oscillators 2 and 3 that receive signals of different frequency bands, the diameter is lower. The superposition of the decrement from the top not only reduces signal interference, but also improves structural stability. In addition, since the signal intensity at the end of the signal receiving is the largest, the superposition of the signals between the upper and lower vibrators should be avoided as close as possible, so that the signal receiving backends of the vibrators in the upper and lower omnidirectional vibrators 2 and 3 are The signal receiving back ends of the vibrators in the adjacent layer omnidirectional oscillators are shifted from each other in the circumferential direction. Theoretically, when the signal receiving end of the upper omnidirectional vibrator 2 is in the same direction as the signal receiving front end of the lower omnidirectional vibrator 3, the distance of the signal intensity of the adjacent layer is the largest, but in actual production, there is an engineering error, so In actual production, according to the specific engineering adjustment, it is generally controlled within 2cm of engineering error in the same direction, as shown in the figure. The signal receiving rear ends 213, 223 and the lower omnidirectional oscillators 312, 362 of the upper omnidirectional vibrator 2 as shown in Fig. 13 are shifted by a certain angle a.
