Description
本发明涉及一种拓宽频率特性的天线，具体涉及一种能自动调节天线振子的分节负荷短波天线。The invention relates to an antenna for widening frequency characteristics, in particular to a sectional load short-wave antenna capable of automatically adjusting an antenna vibrator.
天线是一种变换器，它把传输线上传播的导行波，变换成在无界媒介中传播的电磁波，或者进行相反的变换。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。此外，在用电磁波传送能量方面，非信号的能量辐射也需要天线。一般天线都具有可逆性，即同一副天线既可用作发射天线，也可用作接收天线。同一天线作为发射或接收的基本特性参数是相同的。无线电技术的发展，与天线技术的发展密切相关。现今的短波接收天线设计，一般采用有源和无源两种方法。无源天线的设计，通常采用接收的最大功率与功率密度的比值确定天线的有效口径，即：A＝Pmax/S。式中，A为天线有效口径；Pmax为接收的最大功率；S为功率密度。有源天线的设计，用有源网络的增益来补偿无源天线因尺寸变小所造成的增益下降，从而达到缩减天线尺寸目的。根据传统的无源天线设计原理，设计出来的天线输入阻抗变化很大。传统分节负荷天线设计方式，单纯靠计算很难确定最优加载位置，只有通过不断尝试来确定，这样需反复试验，具有一定盲目性，而且工作量很大。采用有源天线设计原理设计的天线，虽然能拓宽频带，但同时也降低了天线的信噪比和可靠性，增加了互调产物的形成几率，很难获得均匀的输入阻抗。An antenna is a transducer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium, or vice versa. A component used in a radio device to transmit or receive electromagnetic waves. Radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy and other engineering systems, all using electromagnetic waves to transmit information, rely on antennas to work. In addition, non-signal energy radiation also requires an antenna in terms of transmitting energy using electromagnetic waves. Generally, the antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. The same characteristic parameters of the same antenna as transmitting or receiving are the same. The development of radio technology is closely related to the development of antenna technology. Today's short-wave receiving antenna designs generally use both active and passive methods. Passive antenna design usually uses the ratio of the maximum power received to the power density to determine the effective aperture of the antenna, ie: A = Pmax / S. Where A is the effective aperture of the antenna; Pmax is the maximum power received; S is the power density. The design of the active antenna uses the gain of the active network to compensate for the gain reduction caused by the smaller size of the passive antenna, thereby reducing the size of the antenna. According to the traditional passive antenna design principle, the designed antenna input impedance varies greatly. The traditional sectional load antenna design method is difficult to determine the optimal loading position by calculation alone. It can only be determined through continuous trials. This requires trial and error, has certain blindness, and has a large workload. The antenna designed by the active antenna design principle can widen the frequency band, but also reduces the signal-to-noise ratio and reliability of the antenna, increases the probability of formation of intermodulation products, and makes it difficult to obtain a uniform input impedance.
所以如何有效的拓宽频率特性成了目前最值得研究的问题。Therefore, how to effectively widen the frequency characteristics has become the most worthy research problem at present.
发明内容Summary of the invention

本发明通过下述技术方案实现：The invention is achieved by the following technical solutions:
一种能自动调节天线振子的分节负荷短波天线，包括主杆体、以及在主杆体底部设置的支撑架、主杆体顶部设置的T型振子，其特征在于：在主杆体和T型振子的连接处设置加感器，加感器为圆柱形，一端封闭，另一端打开，T型振子通过封闭端的中心连接孔连接在加感器内，其中所述加感器：从连接孔处向外依次包括第一层圆环、第二层圆环、第三层圆环和第四层圆环圈；连接孔直径和第一层圆环的内圆直径相同，第一层圆环的外圆直径和第二层圆环的内圆直径相同，第二层圆环外圆直径和第三层圆环的内圆直径相同，第三层圆环的外圆直径和第四层圆环圈直径相同，加感器的4个组成部分均通过焊接连接；第一层圆环和第三层圆环各设置至少一个小孔。为了解决改善频率特性这一问题，本发明采用加入一个加感器来改善拓宽整个频率特性，为了拓宽天线的工作频率，在天线上分段接入电抗与电阻元件。当一定尺寸振子工作在一个较宽的频率范围内时，在其带通内可能包含几个串联谐振频率和并联谐振频率。这时，如果在垂直天线上加入适当选择谐振频率的加感器，就可以改善由垂直振子和加感器这样几部分串联组成的一个等效网络的频率特性，从而使这种分节负荷天线具有很宽的频率特性，并且根据实际作用对象可利用遗传迭代算法对加载位置进行优化，最终得到最优加载点位置，以及确定整个天线的尺寸以及加感器尺寸和小孔数量。A sectional load short-wave antenna capable of automatically adjusting an antenna element, comprising a main rod body, a support frame provided at the bottom of the main rod body, and a T-type vibrator disposed at the top of the main rod body, characterized in that: the connection between the main rod body and the T-type vibrator The sensor is provided with a sensor, the sensor is cylindrical, one end is closed, and the other end is opened, and the T-type vibrator is connected in the sensor through the central connecting hole of the closed end, wherein the sensor is: from the connecting hole to the outside The first ring, the second ring, the third ring and the fourth ring; the diameter of the connecting hole is the same as the inner diameter of the first ring, and the outer diameter of the first ring The diameter of the inner circle of the second ring is the same, the diameter of the outer circle of the second ring is the same as the diameter of the inner circle of the third ring, and the outer diameter of the third ring is the same as the diameter of the fourth ring. The four components of the sensor are connected by welding; at least one small hole is provided in each of the first ring and the third ring. In order to solve the problem of improving the frequency characteristics, the present invention adopts adding a sensor to improve the widening of the entire frequency characteristic. In order to widen the operating frequency of the antenna, the reactance and the resistance element are segmented on the antenna. When a certain size vibrator operates over a wide frequency range, it may contain several series resonant frequencies and parallel resonant frequencies within its bandpass.

增长天线的作用，加感器所附阻尼电阻将谐振回路的Q值降低，使谐振曲线变钝，以适应宽频带天线的需要，中部加感与杂散电容组成的谐振频率通常选稍低于中心频率，这样就实现了天线振子长度的自动调整作用，从而使输入阻抗和在垂直面中的方向图在很宽的频率范围内变化不大，实现了宽频带。The main rod body is a sectional load antenna, comprising a top rod, a middle rod, a lower rod; a set of series inductance and resistance is added between the top rod and the middle rod; a set of parallel inductance is added between the middle rod and the lower rod and resistance. The upper sensor is a circuit consisting of R, L series, but because the insulator between the top rod and the middle rod has a distributed capacitance between the two, the upper sensor is actually a resonant circuit. When the operating frequency F is lower than Fo, the loop is inductive; when the operating frequency is higher than Fo, the loop is capacitive, and the resistor R1 acts to lower the loop Q value. The central sensor is also a parallel resonant circuit of L, C, R, which has the characteristics similar to the upper sensor. Only the top of the resonant frequency is used to improve the characteristics of the low frequency end. When the receiving frequency is lower than the additive coil and stray capacitance. When the parallel resonant frequency is used, the equivalent impedance is inductive.
The role of the growth antenna, the damping resistor attached to the sensor reduces the Q value of the resonant circuit, making the resonance curve dull to meet the needs of the broadband antenna. The resonant frequency composed of the central sensation and stray capacitance is usually selected to be slightly lower. The center frequency, thus achieving the automatic adjustment of the length of the antenna element, so that the input impedance and the pattern in the vertical plane do not change much over a wide frequency range, achieving a wide frequency band.
