技术领域technical field
本发明涉及通信领域，更具体地说，涉及一种卫星电视天线支架及其卫星电视接收系统。The invention relates to the communication field, and more specifically relates to a satellite TV antenna bracket and a satellite TV receiving system thereof.
背景技术Background technique
传统的卫星电视接收系统是由抛物面天线、馈源、高频头、卫星接收机组成的卫星地面接收站。抛物面天线负责将卫星信号反射到位于焦点处的馈源和高频头内。馈源是在抛物面天线的焦点处设置的一个用于收集卫星信号的喇叭，又称波纹喇叭。其主要功能有两个：一是将天线接收的电磁波信号收集起来，变换成信号电压，供给高频头。二是对接收的电磁波进行极化转换。高频头LNB(亦称降频器)是将馈源送来的卫星信号进行降频和信号放大然后传送至卫星接收机。一般可分为C波段频率LNB(3.7GHz-4.2GHz、18-21V)和Ku波段频率LNB(10.7GHz-12.75GHz、12-14V)。LNB的工作流程就是先将卫星高频讯号放大至数十万倍后再利用本地振荡电路将高频讯号转换至中频950MHz-2050MHz，以利于同轴电缆的传输及卫星接收机的解调和工作。卫星接收机是将高频头输送来的卫星信号进行解调，解调出卫星电视图像或数字信号和伴音信号。The traditional satellite TV receiving system is a satellite ground receiving station composed of parabolic antenna, feed source, tuner and satellite receiver. The parabolic dish is responsible for reflecting the satellite signal into the feed and tuner at the focal point. The feed source is a horn set at the focal point of the parabolic antenna to collect satellite signals, also known as a corrugated horn. There are two main functions: one is to collect the electromagnetic wave signal received by the antenna, transform it into a signal voltage, and supply it to the tuner. The second is to perform polarization conversion on the received electromagnetic waves. The high-frequency head LNB (also known as the down-converter) is to down-frequency and amplify the satellite signal sent by the feeder, and then transmit it to the satellite receiver. Generally, it can be divided into C-band frequency LNB (3.7GHz-4.2GHz, 18-21V) and Ku-band frequency LNB (10.7GHz-12.75GHz, 12-14V). The working process of LNB is to first amplify the satellite high-frequency signal to hundreds of thousands of times, and then use the local oscillator circuit to convert the high-frequency signal to an intermediate frequency of 950MHz-2050MHz, so as to facilitate the transmission of the coaxial cable and the demodulation and work of the satellite receiver. . The satellite receiver is to demodulate the satellite signal sent by the tuner, and demodulate the satellite TV image or digital signal and audio signal.
接收卫星信号时，平行的电磁波通过抛物面天线反射后，汇聚到馈源上。通常，抛物面天线对应的馈源是一个喇叭天线。When receiving satellite signals, the parallel electromagnetic waves are reflected by the parabolic antenna and then converged to the feed source. Usually, the corresponding feed source of the parabolic antenna is a horn antenna.
通常卫星电视天线利用卫星电视支架支撑在地面或其它建筑物的顶部位置，以接收卫星电视信号，但是在传统的卫星电视接收系统中，馈源与卫星电视支架是固定连接的，其位置是固定的，不能调节馈源的角度，这在偏馈卫星电视天线中，尤其不利。Usually, the satellite TV antenna is supported on the ground or on the top of other buildings by a satellite TV bracket to receive satellite TV signals, but in a traditional satellite TV receiving system, the feed source is fixedly connected to the satellite TV bracket, and its position is fixed. Yes, the angle of the feed cannot be adjusted, which is especially unfavorable in bias-fed satellite TV antennas.

For the first artificial microstructure 12 between the substrate unit U and the rear substrate unit V, usually the length, width and height of the metamaterial unit D are not greater than one-fifth of the wavelength, preferably one-tenth of the wavelength. Therefore, according to the operation of the antenna The frequency can determine the size of the metamaterial unit D. Fig. 2 is a perspective drawing, to represent the position in the metamaterial unit D of the first artificial microstructure, as shown in Fig. 2, the first artificial microstructure is sandwiched between the substrate unit U and the rear substrate unit V, The surface on which it is located is represented by SR.

Experiments have proved that when electromagnetic waves pass through a dielectric material with a non-uniform refractive index, they will be deflected toward the direction with a large refractive index. In the case of a certain relative magnetic permeability (usually close to 1), the refractive index is only related to the dielectric constant. In the case of the first substrate selected, metamaterials can be realized by using the first artificial microstructure that only responds to the electric field. Any value of the unit refractive index (within a certain range), under the center frequency of the antenna (12.5GHZ), use simulation software, such as CST, MATLAB, etc., to obtain an artificial microstructure of a specific shape through simulation (as shown in Figure 5 The dielectric constant of the planar snowflake-like metal microstructure) changes with the change of the topological shape, and the data corresponding to each other can be listed, and the core layer of the specific refractive index distribution we need can be designed. For the sheet 11 , similarly, the refractive index distribution of the impedance matching layer sheet can be obtained, thereby obtaining the refractive index distribution of the entire metamaterial panel 100 .

In the present invention, the first front substrate and the first rear substrate of the first substrate are made of the same FR-4 composite material, and the FR-4 composite material has a predetermined dielectric constant, for example FR-4 composite material with a dielectric constant of 3.3.
(2)确定超材料单元的尺寸。超材料单元的尺寸的尺寸由天线的中心频率得到，利用频率得到其波长，再取小于波长的五分之一的一个数值做为超材料单元D的长度CD与宽度KD。本发明中，所述超材料单元D为如图2所示的长CD与宽KD均为2.5mm、厚度HD为0.818mm的方形小板。(2) Determine the size of the metamaterial unit. The size of the metamaterial unit is obtained from the center frequency of the antenna, its wavelength is obtained by using the frequency, and a value less than one-fifth of the wavelength is taken as the length CD and width KD of the metamaterial unit D. In the present invention, the metamaterial unit D is a small square plate with a length CD and a width KD of 2.5 mm and a thickness HD of 0.818 mm as shown in FIG. 2 .
(3)确定金属微结构的材料及拓扑结构。本发明中，金属微结构的材料为铜，金属微结构的拓扑结构为图5所示的平面雪花状的金属微结构，其线宽W各处一致；此处的拓扑结构，是指拓扑形状演变的基本形状。(3) Determine the material and topology of the metal microstructure. In the present invention, the material of the metal microstructure is copper, and the topological structure of the metal microstructure is a plane snowflake-like metal microstructure shown in Figure 5, and its line width W is consistent everywhere; the topological structure here refers to the topological shape Evolved basic shapes.
(4)确定金属微结构的拓扑形状参数。如图5所示，本发明中，平面雪花状的金属微结构的拓扑形状参数包括金属微结构的线宽W，第一金属线J1的长度a，第一金属分支F1的长度b。(4) Determine the topological shape parameters of the metal microstructure. As shown in FIG. 5 , in the present invention, the topological shape parameters of the planar snowflake-like metal microstructure include the line width W of the metal microstructure, the length a of the first metal line J1 , and the length b of the first metal branch F1 .
(5)确定金属微结构的拓扑形状的演变限制条件。本发明中，金属微结构的拓扑形状的演变限制条件有，金属微结构之间的最小间距WL(即如图8所示，金属微结构与超材料单元的长边或宽边的距离为WL/2)，金属微结构的线宽W，超材料单元的尺寸；由于加工工艺限制，WL大于等于0.1mm，同样，线宽W也是要大于等于0.1mm。本发明中，WL取0.1mm，W取0.3mm，超材料单元的尺寸为长与宽为2.5mm，厚度为0.818mm，此时金属微结构的拓扑形状参数只有a和b两个变量。金属微结构的拓扑形状的通过如图8至图9所示的演变方式，对应于某一特定频率(例如12.5GHZ)，可以得到一个连续的折射率变化范围。(5) Determine the evolution constraints of the topological shape of the metal microstructure. In the present invention, the evolution restriction condition of the topological shape of the metal microstructure has, the minimum spacing WL between metal microstructures (that is, as shown in Figure 8, the distance between the metal microstructure and the long side or wide side of the metamaterial unit is WL /2), the line width W of the metal microstructure, and the size of the metamaterial unit; due to the limitation of the processing technology, WL is greater than or equal to 0.1mm, and similarly, the line width W must also be greater than or equal to 0.1mm. In the present invention, WL is 0.1mm, W is 0.3mm, the size of the metamaterial unit is 2.5mm in length and width, and the thickness is 0.818mm. At this time, the topological shape parameters of the metal microstructure only have two variables, a and b. The evolution of the topological shape of the metal microstructure corresponds to a specific frequency (for example, 12.5 GHZ) as shown in FIG. 8 to FIG. 9 , and a continuous range of refractive index variation can be obtained.
具体地，所述金属微结构的拓扑形状的演变包括两个阶段(拓扑形状演变的基本形状为图5所示的金属微结构)：Specifically, the evolution of the topological shape of the metal microstructure includes two stages (the basic shape of the topological shape evolution is the metal microstructure shown in Figure 5):
第一阶段：根据演变限制条件，在b值保持不变的情况下，将a值从最小值变化到最大值，此演变过程中的金属微结构均为“十”字形(a取最小值时除外)。本实施例中，a的最小值即为0.3mm(线宽W)，a的最大值为(CD-WL)，即2.5-0.1mm，则a的最大值为2.4mm。因此，在第一阶段中，金属微结构的拓扑形状的演变如图8所示，即从边长为W的正方形JX1，逐渐演变成最大的“十”字形拓扑形状JD1，在最大的“十”字形拓扑形状JD1中，第一金属线J1与第二金属线J2长度均为2.4mm，宽度W均为0.3mm。在第一阶段中，随着金属微结构的拓扑形状的演变，与其对应的超材料单元的折射率连续增大((对应天线一特定频率)，当频率为12.5GHZ时，超材料单元对应的折射率的最小值nmin为1.91。The first stage: According to the evolution constraints, under the condition that the value of b remains unchanged, the value of a is changed from the minimum value to the maximum value. except). In this embodiment, the minimum value of a is 0.3 mm (line width W), the maximum value of a is (CD-WL), that is, 2.5-0.1 mm, and the maximum value of a is 2.4 mm. Therefore, in the first stage, the evolution of the topological shape of the metal microstructure is shown in Figure 8, that is, from a square JX1 with a side length W to the largest topological shape JD1 of a "ten". In the ""-shaped topological shape JD1, the length of the first metal line J1 and the second metal line J2 are both 2.4 mm, and the width W is 0.3 mm. In the first stage, with the evolution of the topological shape of the metal microstructure, the refractive index of the corresponding metamaterial unit increases continuously ((corresponding to a specific frequency of the antenna), when the frequency is 12.5GHZ, the corresponding metamaterial unit The minimum value nmin of the refractive index is 1.91.
第二阶段：根据演变限制条件，当a增加到最大值时，a保持不变；此时，将b从最小值连续增加到最大值，此演变过程中的金属微结构均为平面雪花状。本实施例中，b的最小值即为0.3mm(线宽W)，b的最大值为(CD-WL-2W)，即2.5-0.1-2*0.3mm，则b的最大值为1.8mm。因此，在第二阶段中，金属微结构的拓扑形状的演变如图9所示，即从最大的“十”字形拓扑形状JD1，逐渐演变成最大的平面雪花状的拓扑形状JD2，此处的最大的平面雪花状的拓扑形状JD2是指，第一金属分支J1与第二金属分支J2的长度b已经不能再伸长，否则第一金属分支与第二金属分支将发生相交，b的最大值为1.8mm。此时，第一金属线与第二金属线长度均为2.4mm，宽度均为0.3mm，第一金属分支及第二金属分支的长度均为1.8mm，宽度为0.3mm。在第二阶段中，随着金属微结构的拓扑形状的演变，与其对应的超材料单元的折射率连续增大(对应天线一特定频率)，当频率为12.5GHZ时，超材料单元对应的折射率的最大值nmax为5.6。The second stage: According to the evolution constraints, when a increases to the maximum value, a remains unchanged; at this time, b is continuously increased from the minimum value to the maximum value, and the metal microstructure in this evolution process is planar snowflake shape. In this embodiment, the minimum value of b is 0.3mm (line width W), the maximum value of b is (CD-WL-2W), that is, 2.5-0.1-2*0.3mm, then the maximum value of b is 1.8mm . Therefore, in the second stage, the evolution of the topological shape of the metal microstructure is shown in Fig. 9, that is, from the largest "ten" topological shape JD1 to the largest planar snowflake-like topological shape JD2, where The largest planar snowflake topological shape JD2 means that the length b of the first metal branch J1 and the second metal branch J2 can no longer be extended, otherwise the first metal branch and the second metal branch will intersect, and the maximum value of b is 1.8mm. At this time, the length of the first metal line and the second metal line are both 2.4 mm and the width is 0.3 mm, and the length of the first metal branch and the second metal branch are both 1.8 mm and the width is 0.3 mm. In the second stage, with the evolution of the topological shape of the metal microstructure, the refractive index of the corresponding metamaterial unit increases continuously (corresponding to a specific frequency of the antenna). When the frequency is 12.5GHZ, the corresponding refraction index of the metamaterial unit The maximum value nmax of the rate is 5.6.
通过上述演变得到超材料单元的折射率变化范围(1.91-5.6)满足设计需要。如果上述演变得到超材料单元的折射率变化范围不满足设计需要，例如最大值太小，则变动WL与W，重新仿真，直到得到我们需要的折射率变化范围。Through the above evolution, the refractive index variation range (1.91-5.6) of the metamaterial unit meets the design requirements. If the range of refractive index variation obtained from the above evolution does not meet the design requirements, for example, the maximum value is too small, then change WL and W, and re-simulate until the range of refractive index variation we need is obtained.
根据公式(1)，将仿真得到的一系列的超材料单元按照其对应的折射率排布以后(实际上就是不同拓扑形状的多个第一人造微结构在第一基材上的排布)，即能得到本发明的核心层片层。According to formula (1), after a series of metamaterial units obtained by simulation are arranged according to their corresponding refractive indices (in fact, it is the arrangement of multiple first artificial microstructures of different topological shapes on the first substrate) , that is, the core layer sheet of the present invention can be obtained.
同理，可以得到本发明的阻抗匹配层片层。Similarly, the impedance matching layer of the present invention can be obtained.

(2)设计好超材料面板的整体结构参数，在制造前即将其分成多个单元板1000，对这些单元板单独加工制造。这种方式非常适合超大型的超材料面板加工。(2) Design the overall structural parameters of the metamaterial panel, divide it into a plurality of unit plates 1000 before manufacturing, and process and manufacture these unit plates separately. This method is very suitable for ultra-large metamaterial panel processing.
