Description

一种在30MHz-1350MHz频率范围有源无源结合的超短波天线An ultrashort wave antenna with active passive combination in the frequency range of 30MHz-1350MHz 技术领域Technical field
本发明涉及一种在提高灵敏度的超短波天线，具体涉及一种在30MHz-1350MHz频率范围有源无源结合的超短波天线。The invention relates to an ultrashort wave antenna for improving sensitivity, in particular to an ultrashort wave antenna active and passively combined in a frequency range of 30 MHz to 1350 MHz.
背景技术Background technique
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，设计出来的天线频率范围不可能在30MHz---1350MHz频率范围内达到较高的辐射效率，而且输入阻抗变化很大。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 frequency range is unlikely to achieve high radiation efficiency in the frequency range of 30MHz - 1350MHz, and the 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.
所以如何有效的提高天线频率范围在30MHz---1350MHz频率范围内的灵敏度和拓宽频率特性成了一项值得研究的课题。Therefore, how to effectively improve the sensitivity and widening frequency characteristics of the antenna frequency range in the frequency range of 30MHz - 1350MHz has become a subject worth studying.
