天线手册(Antenna Handbook)概要

天线手册(Antenna Handbook)天线手册(Antenna Handbook)天线基本概念天线是FM DX的耳朵，微弱的电波从天线经过馈线进入接收机，才能让我们听到远方天线电波在讲天线之前，不能不先提一提电波。

我们制作天线的目的是为了捕捉电波，因此，在考虑天线的问题之前，绝对有必要先研究一下电波的问题。

FM天线直接波这是指从发射天线到接收天线之间，不经过任何发射，直接到达，电波就象一束光一样，所以有人称它为视线传播。

视线传播这个名字也表明了这种传播方式能够传播的距离不远。

这有两个原因，首先是电波从发射点出发，其能量是以幂级数递减的，而接收机要能良好地解调出广播，需要一定的信号强度。

所以太远的地方，信号太弱，不足以解调。

如果只是这个原因，那么拼命提高发射功率或增加接收天线的增益，也许就可以扩大收听的范围了。

但是，还有一个重要的问题是，地球是圆的，在地球上任何一点发出的电波，按直线前进的方向，最终将离开地球射向天空。

主要是由于第二个原因，一般地讲，地面上一个发射台发出的直线波，只能传播到70km远处地面上的接收处。

如果双方的高度增加，那么这个距离还可以增加，但总是有限的。

所以，70km，是本地收听的极限，实际上，由于山脉、丘陵、房屋的阻挡、反射，这个距离还要大打折扣，一般可以估计的距离是35km。

电离层发射波这是指电波通过电离层的发射达到接收方。

这里面的名堂很多。

电离层本身是有多个层次的，支持短波（1.8MHz到30MHz）反射的电离层是F1和F2 层。

F1和F2并不是甘心反射所有的地波和大气波导本来来说，理论上VHF是不存在地波的。

但是无数的实践表明，VHF 也存在着某种程度的地波传播。

所以我们能稳定地接收200km左右电台的信号。

江苏和安徽两省的业余电台，每年国庆的时候都进行全省VHF移动通讯实验，也证明了VHF电波可以在200km左右的距离得到传播。

大气波导是另外一种可能传播VHF电波的手段，不过人们研究得还不够多。

空腔双工器的原理和调试

空腔双工器的原理和调试双工器是有着尖锐的调谐持性的装置，用来隔离接收和发射。

它允许一根天线完成发射和接收，而不用担心发射装置的射频能量去轰击接收机。

当然，那样做必须将发射频率和接收频率分开，称为频差。

在2米波段的频差是600KHZ；在70Cm波段有着较大的宽度，是5MHZ。

通常，双工器工作在狭窄的通频带上，有着不可思议的陡峭的截止曲线。

不同于一般意义上的高通或低通滤波器。

有好几种方法来实现双工器，业余上常用空腔和相位线的方法。

《ARRL》手册上有详尽的工作原理。

《ARRL》手册上也给出了六空腔的双工器，之后又解释了其工作原理。

我也按照做了一个并让它工作，但我发现这个设计调谐起来非常困难，信噪比也一直不稳定，所以我不想在这里介绍它们。

我相信，现在已经有调谐简单实际可行的双工器被设计制造出来了。

我一直推崇的一款双工器是名叫"华康"(Wacom)的设计。

它用4个8吋的腔体构成“带通(band pass)/带阻(band reject)”模式。

借助于高Q值的腔体和良好的设计，Wacom 仅用4个腔体就有相当于6个腔体的良好表现。

唯一的缺点是费用较高。

图一详细给出了它的结构，其中两个腔体组成一组与发射机输出端连接；另外两个与接收机输入端连接。

用“T”型接头将它们连接起来，再通过同轴电缆与天线相连。

图一四腔带通/带阻双工器连接图每个腔体都有二个功能。

第一，必须通过想得到的信号（即带通或通带）；第二，必须尽可能阻止不想要的信号（即带阻或阻带）。

在（图2）中我给出了用于发射的空腔滤波器典型响应曲线。

请注意，它在145.37MHZ的发射频率上通过了几乎所有的信号，并且在接收频率处，即低于发射频率600KHZ处有着-30dB+的衰减。

同样，两个接收腔体也精确地匹配，除了它们的通频点在144.77MHZ的接收频率上外，它们阻带的谷点都在发射频率145.37MHZ上。

这样，发射腔体将滤除发射机所产生的较宽频带上的噪声（殘余发射）使其不进入接收机，而接收腔体也将滤除发射机产生的射频功率使其不进入接收机。

常用卫星通信天线介绍

常用卫星通信天线介绍天线是卫星通信系统的重要组成部分，是地球站射频信号的输入和输出通道，天线系统性能的优劣影响整个通信系统的性能。

地球站与卫星之间的距离遥远，为保证信号的有效传输，大多数地球站采用反射面型天线。

反射面型天线的特点是方向性好，增益高，便于电波的远距离传输。

反射面的分类方法很多，按反射面的数量可分为双反射面天线和单反射面天线；按馈电方式分为正馈天线和偏馈天线；按频段可分为单频段天线和多频段天线；按反射面的形状分为平板天线和抛物面天线等。

下文对一些常用的天线作简单介绍。

1．抛物面天线抛物面天线是一种单反射面型天线，利用轴对称的旋转抛物面作为主反射面，将馈源置于抛物面的焦点F上，馈源通常采用喇叭天线或喇叭天线阵列，如图1所示。

发射时信号从馈源向抛物面辐射，经抛物面反射后向空中辐射。

由于馈源位于抛物面的焦点上，电波经抛物面反射后，沿抛物面法向平行辐射。

接收时，经反射面反射后，电波汇聚到馈源，馈源可接收到最大信号能量。

图1 抛物面天线抛物面天线的优点是结构简单，较双反射面天线便于装配。

缺点是天线噪声温度较高；由于采用前馈，会对信号造成一定的遮挡；使用大功率功放时，功放重量带来的结构不稳定性必须被考虑。

2．卡塞格伦天线卡塞格伦天线是一种双反射面天线，它由两个发射面和一个馈源组成，如图2所示。

主反射面是一个旋转抛物面，副反射面为旋转双曲面，馈源置于旋转双曲面的实焦点F1上，抛物面的焦点与旋转双曲面的焦点重合，即都位于F2点。

从从馈源辐射出来的电磁波被副反射面反射向主反射面，在主反射面上再次被反射。

由于主反射面的焦点与副反射面的焦点重合，经主副反射面的两次反射后，电波平行于抛物面法向方向定向辐射。

对经典的卡塞格伦天线来说，副反射面的存在遮挡了一部分能量，使得天线的效率降低，能量分布不均匀，必须进行修正。

Narda-STS 5G FR2 天线数据手册说明书

Datasheet 5G FR2 AntennasMeasurement of 5G NR FR2 Electromagnetic FieldsDownconverter-Antennas for omnidirectional and directional measurement of fields and their sources in the frequency range from 24.25 GHz to 29.5 GHzWith the downconverter antennas, the user gets the pos-sibility to extend the frequency range of the SRM-3006 to frequencies from 24.25 GHz to 29.5 GHz. One of the main applications is to demonstrate compliance with the EMF limits in frequency range FR2 of the 5G NR mo-bile radio service. Of course all other applications in this frequency range can also be measured. The two anten-nas differ in their reception characteristics: The Model 3591/01 features a directional characteristic, while the Model 3591/02 offers an omnidirectional characteristic.›Extends SRM-3006 to cover 24.25 GHz to 29.5 GHz.›Calibrated antennas for reliable measurements ›Measurements are displayed in field strength or in percent of limit values, e.g. ICNIRP , FCC...›Omnidirectional antenna design for environmental measurements›Directional antenna design for weak signals ›Easy to setup ›Simple operation›Fast and reliable measurement resultsTwo different antenna models are available. A directional anten -na with high sensitivity and an omnidirectional antenna. Both antennas include a downconverter that converts the millimeter wave between 24.25 GHz to 29.5 GHz into the SRM-3006’s receive band. This means that the RF cable between antenna and basic unit only transmits frequencies up to a maximum of 6 GHz, which greatly reduces the cable loss compared with a 20 GHz cable. In addition, the downconverter in the antenna avoids the need to modify the base unit, so the antenna can be used on all SRM-3006 devices without hardware modifications. Only a firmware update is required, which can be done by the user.The antennas have their own batteries, independent from the basic unit. So the runtime of the SRM is not affected by the op -eration of the downconverter antenna. The battery integrated in the antenna can be charged via an USB-C socket. Connected to a USB power bank, long-term measurements can also be performed.Narda recommends to operate the antennas only via an exten-sion cable with the SRM.Measurement of weak signals (e.g. indoors):For measurements inside buildings, the field strengths are often very low. For example, a modern, coated glass window can at-tenuate a signal at 24 GHz by about 30 dB. To be able to detect such a field strength, a high gain antenna is needed. However, such antennas have a high directivity due to their principle. The antenna model 3591/01 has such a characteristic.In addition, the directional characteristic can be used to detect the field strength of geographically separated base stations..Outdoor environmental measurements:For EMF measurements, national as well as international standards recommend an isotropic measurement. Such anten-nas are not available for the FR2 frequency range. The antenna 3591/02 offers an omnidirectional reception characteristic that roughly corresponds to that of a donut. Ideal reception results are therefore obtained from an X-Y spatial plane. To cover all three spatial axes for isotropic measurements, the antenna must be connected to the basic unit via an RF cable and moved accordingly during the measurement.Available Antenna ModelsFig. 1.3591/01 Directional Antenna (Horn antenna)Fig. 2. 3591/02 OmnidirectionalConditionsUnless otherwise noted, specifications apply after 30 minutes warm-up time within the specified environmental conditions.
