antenna是什么接口

  antenna接口介绍:   antenna是一个圆圆的天线接口,天线接口是无线设备的一个接口端,无线设备本身的天线都有一定距离的限制,当超出这个限制的距离,就要通过这些外接天线来增强无线信号,达到延伸传输距离的目的,涉及到三个概念。   1、频率范围它是指天线工作的频段,这个参数决定了它适用于哪个无线标准的无线设备。   2、增益值此参数表示天线功率放大倍数,数值越大表示信号的放大倍数就越大,也就是说当增益数值越大,信号越强,传输质量就越好。   3、天线接口主要是针对可以拆装及外接天线的无线设备,针对不同的接口正确匹配相应的天线,达到增大信号及延伸距离的功能。

今天发现买的二手车上有个GPSantenna,这个是干什么用的?

这是天线,是接收卫星信号的。GPS分为主机和天线两个部分,天线是接收卫星信号的,而主机是存储和处理卫星信号来为客户提供位置等信息的。汽车天线是一个静电释放器,主要是将行驶中汽车外壳积聚的静电释放出来,保护乘员安全和汽车电路。扩展资料:一般汽车上的天线用于车上的收音机和电台,可分汽车内置天线和外置天线。但根据不同用途的汽车也有安装其他的天线。如公交车有DVB-T天线,车载TV天线。物流及出租车还装有GSM天线、GPS卫星天线。收音机和电台天线主要就是AM/FM天线、软PCB数字天线、AM/FM/TV天线等。根据不同的功能和用途,所用的天线的频率也不同。汽车天线是指设计安装在车辆上的移动通讯天线,最常见就是吸盘天线。由于吸盘天线安装摆放容易,所以在一些简易设台场合常常用吸盘天线代替基地天线。

antenna effect是什么以及如何预防

天线效应(Antenna effect)一个小尺寸MOS管的栅极与具有很大面积的第一层金属线连接在一起,在刻蚀第一层金属是,这片金属就像一根“天线”,收集离子,使其电位升高,在制造过程中可能MOS管的栅电压可增大到使栅氧化层击穿,这个击穿不可恢复。这个就是天线效应。任何与栅极连接的大片的导电材料,包括多晶硅本身,都可能产生天线效应。一般采用跳线,来避免天线效应,列如M1,使用Via12,跳M2来走线,即可避免。

gps antenna与gps active antenna区别

两者都是GPS天线,分GPS有源天线(GPS Active Antenna)和无源天线(GPS Passive Antenna)两种。两者的区别在于:有源天线(Active Antenna),有放大电路,需要供电,所以增益高,但价格也高;无源天线(Passive Antenna),无放大电路,不需要供电,所以增益低,价格也低。如果是有源的,厂家肯定会冠以Active,而无源的,不一定会冠以Passive,不过你可以从两者的增益与价格比较来判断。

常见的天线类型有哪些

我们最常见的12种天线。1、 水平半波偶极天线(Dipole Antenna),也称DP天线这种天线,由两根长度相等的导体,水平或倾斜架设而成,是一种最简单、最基本的天线。天线的总长度大概等于半波长的95%,两个振子都是1/4波长的95%。该天线的辐射方向,是以天线为对称轴,馈电点为切点的两个圆。除了水平架设以外,GP天线还可以倒V(正V)架设——天线的夹角在110度至120度之间,通过改变了发射仰角,来协调远距离和近距离的通信。有时候,会在巴伦(一种连接振子和电缆的三端口器件)上加装多对振子,使天线能够工作在更多的波段上。5波段短波倒V天线(看上去像雨伞的伞骨)除了水平和倒V,DP天线还衍生出了很多其它种类的天线。2、垂直单极天线(Vertical Antenna),也称GP天线GP天线就是源自偶极天线的一种变形天线。天线底端通过与馈线的内导体相连,馈线的外导体与地网相连,水平方向上辐射是一个圆。因此,该天线在各个方向上的接收和发射能力相同,适合做全向接收发射。通常,移动手持设备采用GP天线居多。此外,我们经常在户外爱好者越野车上看到的天线,也是一种垂直GP天线,工作在U/V波段。3、 温顿天线(Window Antenna),又称偏馈半波天线这种天线多半是用一根单导线制成,馈线也是单导线,接在偏离中心点14%的地方,普遍的情况是用作接收天线,也有做发射天线的。温顿天线因为占地小,便于携带,适合无线电爱好者使用。4、八木天线(Yagi Antenna)大名鼎鼎的八木天线,1925年由当时的日本东北大学担任部长的八木秀次和宇田新太郎发明。“Yagi”是八木的英文拼写,并不是说有“八根木头”。这种天线由多个单元组成,并且具有较强的方向性,引向器越多,方向性越强,增益也越高。八木天线可以在多个波段上工作,有时候也用于无线电测向。5、碟形天线(Dish Antenna)专门用于长距离通讯的高方向性天线,有极窄的波束宽度与很高的增益值,也可称为高增益指向性天线。这种天线通常用于点对点的通讯连接,天线彼此之间必须很精准的瞄准,而且天线之间的直视(Lightu2002ofu2002Sight)必须没有任何阻碍物。

车载gps active antenna 是干什么用的

车载gps active antenna 是GPS有源天线,接收GPS信号用的。GPS就是通过接收卫星信号,进行定位或者导航的终端。而接收信号就必须用到天线。信号强度为-166dBW左右,属于比较弱的信号。,这些特点决定了要为GPS信号的接收准备专门的天线。GPS天线从供电方面又分有源和无源。外置式GPS为有源天线,比方达伽马GPS外置式天线基本上就属于有源天线。那无源天线就是不含LNA放大器,只是天线本体。扩展资料:无源GPS天线:使用无源GPS天线时,由于只有一个陶瓷片接收天空的卫星信号,直接连接到模块的RF-IN脚,这种联接方式结构简单,而且标准的25*25*4的陶瓷片成本低廉,技术成熟,占空体积小,适合于强调紧凑型空间GPS导航产品,蓝牙GPS,手机GPS及其他小型GPS消费类产品。有源GPS天线:通常对于设备或车载机而言,由于设备与GPS接收模块之前往往有距离,考虑到安装的便利性可能会有超过1米的距离,在这种情况下我们只能选择有源GPS天线,由于天线长度的信号衰减需要进行补偿,一般有两级低噪声放大器(LNA)进行天线前端信号放大,放大后的信号经电缆输出,电缆同步提供LNA所需要的直流电压。参考资料来源:百度百科-GPS天线

active antenna system的主要功能模块包括哪些

可以简单理解为:有电路需要供电的天线就是Active Antenna(“有源天线”或“主动天线”),没有电路的是Passive Antenna(“无源天线”或“被动天线”)首先要了解的是GPS定位器有定位模块接收GPS免费信号,然后有处理模块分析处理数据,最后有通信模块,也就是流量卡,用流量卡把处理好的定位信息传送到指定的网络IP地址上,从而实现了后台客户端定位跟踪显示,客户端有电脑客户端和手机客户端,但必须要上网。自己如果需要可以去汽配城和GPS公司安装,几百块而已,记着要软件客户端、账号和密码。祝您羊年大吉,对你有帮助请采纳啊!百度文库给你http://wenku.baidu.com/link?url=M18h73gaDKFQsG5Zm0PMg17lwrIxoaFZfZwJNiqhU95U4CtjrFeEz8ktD_EWmeKiIhjmZ-mc_SNso1T8qL0njMfMs05QKMrfyA-0bjhsVZG

请问哪位高人能给我解释下Antenna-Coupling Capacitor(天线耦合电容)的作用

aa电容特性是阻断直流,信号频率越低容抗越大,天线耦合电容能使高频信号顺利从天线传送到下一级电路,而人摸天线因人体感应的低频信号被电容阻挡不能传送到下级电路,这样不会产生干扰。

天线理论英文1# Introduction to Antennas

http://www.antenna-theory.com/intro/main.php In the 1890s, there were only a few antennas in the world. These rudimentary devices were primarly a part of experiments that demonstrated the transmission of electromagnetic waves. By World War II, antennas had become so ubiquitous that their use had transformed the lives of the average person via radio and television reception. The number of antennas in the United States was on the order of one per household, representing growth rivaling the auto industry during the same period. By the early 21st century, thanks in large part to mobile phones, the average person now carries one or more antennas on them wherever they go (cell phones can have multiple antennas, if GPS is used, for instance). This significant rate of growth is not likely to slow, as wireless communication systems become a larger part of everyday life. In addition, the strong growth in RFID devices suggests that the number of antennas in use may increase to one antenna per object in the world (product, container, pet, banana, toy, cd, etc.). This number would dwarf the number of antennas in use today. Hence, learning a little (or a large amount) about of antennas couldn"t hurt, and will contribute to one"s overall understanding of the modern world. What is the origin of the antenna? I"m ruling out such early devices as compasses, because while they in some sense receive a magnetic field, it is not an electromagnetic field. Ben Franklin"s kite experiment wasn"t quite an antenna, as that captured lightning discharge, which is a direct current path where the energy is not transferred independent of the medium it travels. The human eye of course receives high frequency electromagnetic waves (light, to the layman). Technically the eye could be classified as an antenna; however since it can"t transmit waves, it is really a sensor, so I"ll exclude that as well. The first experiments that involved the coupling of electricity and magnetism and showed a definitive relationship was that done by Faraday somewhere around the 1830s. He slid a magnetic around the coils of a wire attached to a galvanometer. In moving the magnet, he was in effect creating a time-varying magnetic field, which as a result (from Maxwell"s Equations), must have had a time-varying electric field. The coil acted as a loop antenna and received the electromagnetic radiation, which was received (detected) by the galvanometer - the work of an antenna. Interestingly, the concept of electromagnetic waves had not even been thought up at this point. Heinrich Hertz developed a wireless communication system in which he forced an electrical spark to occur in the gap of a dipole antenna . He used a loop antenna as a receiver, and observed a similar disturbance. This was 1886. By 1901, Marconi was sending information across the atlantic. For a transmit antenna, he used several vertical wires attached to the ground. Across the Atlantic Ocean, the receive antenna was a 200 meter wire held up by a kite [1]. In 1906, Columbia University had an Experimental Wireless Station where they used a transmitting aerial cage. This was a cage made up of wires and suspended in the air, resembling a cage [2]. A rough outline of some major antennas and their discovery/fabrication dates are listed: Current research on antennas involves metamaterials (materials that have engineered dielectric and magnetic constants, that can be simultaneously negative, allowing for interesting properties like a negative index of refraction). Other research focuses on making antennas smaller, particularly in communications for personal wireless communication devices (e.g. cell phones). A lot of work is being performed on numerical modeling of antennas, so that their properties can be predicted before they are built and tested. References: [1] Balanis, Constantine. "Antenna Theory: A Review", Proceedings of the IEEE, vol. 80, January 1992. [2] W2AEE Antenna History. Arthur M. Kay, scanned by Alan Crosswell. http://www.w2aee.columbia.edu/history/antenna-history.html A good book on antenna theory would look nice on your bookshelf. And girls really like antenna books. Sometimes you get sick of reading things on the internet, and want a comprehensive antenna book to read. On this page, I"ll review some of the popular antenna books available. The first 3 of these books are more theoretical and have a good chunk of math in them and less hands on material. These books are tricky to write because the math for antennas gets extremely complicated quickly, so once an antenna has a non-simple shape (not a wire), the math becomes intractable. So there"s always a tradeoff in complex math and what you really need to know to learn about antennas. The last 2 are more hands on build-your-own antenna type books, where you can learn what you need to without unnecessary math. 1. Antenna Theory Constantine A. Balanis is a well known name in the antenna world. To be fare, he was my dissertation adviser, so I"m a little biased. He"s a surprisingly sociable guy for an antenna person. Anyway, about his book Antenna Theory: Analysis and Design . This is the largest of the major antenna books, and is used by a large number of American Universities in teaching undergraduate and graduate level courses on antennas. He is very thorough, and tries to walk through the concepts and tractable derivations throughout the book. The thoroughness is often considered a fault by some people, in that things are explained sometimes in a long-winded manner. However, this is often advantageous if you haven"t seen the material in a while. He treats all the major antenna types, discusses arrays, has a chapter on measurements and smart antennas. All in all, this is a good book and understandable. It is quite large though. And if after a thousand pages or so you still want more, the book does come with a CD for visualizing things and aids in understanding certain concepts, if you are interested in that sort of thing. 2. Antenna Theory and Design This book is much smaller than Balanis" book. Despite its size, this book manages to hit a large number of the topics that Balanis does. The math is probably more advanced than that in Balanis" book, but nothing intractable if you are well versed in your undergraduate level vector calculus. One problem with it is that some topics are only glossed over with little detail, such as slot antennas. References are provided if you are so inclined and wish to learn more. All in all, I think this book is great and if you are a quick learner you will probably prefer this to Balanis. If you"ve been out of practice for a while or are rusty on things like math you might be better off with Balanis" book. 3. Antennas This book has good photographs and figures. The math is challenging and some people dislike it because a lot of the text focuses on using math to simplify things or derive auxilliary sources or things like that. However, the author does make an attempt to explain what the math means. This book would work as your antenna theory textbook. For whatever reason, I believe it has fallen out of favor somewhat with the new generation of engineers, but if you are looking to learn how antennas radiate and about the fundamental antennas, this book will take you there. 4. Practical Antenna Handbook This book, The Practical Antenna Handbook (Joseph Carr) will be very helpful to a lot of people. If you are a practical, hands on guy and don"t care about stupid complex math that doesn"t matter, this book is for you. This book contains step-by-step instructions for building antennas and attempts to make everything real-world and not theoretical as some of the former books do. If you are going to be a research antenna engineer and publish papers, you don"t want to start with this book. But if you are into building things and just want to slap on workable antennas to your projects or get a hands on overview of making transmitters and receivers work, this book will do nicely. And true masters of the antenna world should have knowledge of both the theory and the practical skills. So if you are purely a math jockey and need to expand your knowledge base, this might be a good book to pick up, and is fairly priced. 5. The ARRL Antenna Book Another practical handbook is The ARRL Antenna Book: The Ultimate Reference for Amateur Radio Antennas, Transmission Lines And Propagation . This book is a classic, and I mean it goes back to 1939 before people even knew antennas existed. This is a good book for practicing engineers and amateurs, as it attempts to give the theory and hands on antenna projects. While this book does date back to 1939, it has been updated to include modern techniques, such as the slide rule (joke). It incorporates reference to Vector Network Analyzers (VNA), a must have antenna measurement tool. At just under 1000 pages, this is a large book, but well worth the price. Also covers transmission line theory and propagation, which should be understood as well. In sum, everyone who I know who owns the book swears by it. They love it. It provides a good balance between the required theoretical skills and hands on techniques that make for a solid antenna engineer. This page has been written by a small but finite set of aliens with a passion for spreading antenna knowledge. While this passion may seem strange, it is actually quite common outside the milky way. A human or two has contributed to this page (notably Peter Bevelacqua), but they are mainly kept on the team to understand the web-human interface. Keep watching the stars. McNasty, 0*3^H:2

什么是printed antenna。。天线

这个主要在高频和射频电路中出现。在这种电路中,为了减少体积,提高系统的可靠性,往往会采用一些特殊做法,也就是用电路板上特别设计的走线来作为天线(因为频率高,天线尺寸也不大,可以用走线实现),这个走线是在印制电路板(PCB)制作的时候就做上去的,所以就称为printed antenna,也就是用印制方式加工生产的天线。

GPS有什么组成?

  老兄,你是要问GPS定位仪还是GPS导航仪?  如果是GPS构成,那我复制给你吧。呵呵  GPS组成部分:  1.空间部分  GPS的空间部分是由24颗卫星组成(21颗工作卫星;3颗备用卫星),它位于距地表20200km的上空,均匀分布在6 个轨道面上(每个轨道面4 颗),轨道倾角为55°。卫星的分布使得在全球任何地方、任何时间都可观测到4 颗以上的卫星,并能在卫星中预存导航信息,GPS的卫星因为大气摩擦等问题;随着时间的推移,导航精度会逐渐降低。  2. 地面控制系统  地面控制系统由监测站(Monitor Station)、主控制站(Master Monitor Station)、地面天线(Ground Antenna)所组成,主控制站位于美国科罗拉多州春田市(Colorado Spring)。地面控制站负责收集由卫星传回之讯息,并计算卫星星历、相对距离,大气校正等数据。  3.用户设备部分  用户设备部分即GPS 信号接收机。其主要功能是能够捕获到按一定卫星截止角所选择的待测卫星,并跟踪这些卫星的运行。当接收机捕获到跟踪的卫星信号后,就可测量出接收天线至卫星的伪距离和距离的变化率,解调出卫星轨道参数等数据。根据这些数据,接收机中的微处理计算机就可按定位解算方法进行定位计算,计算出用户所在地理位置的经纬度、高度、速度、时间等信息。接收机硬件和机内软件以及GPS 数据的后处理软件包构成完整的GPS 用户设备。GPS 接收机的结构分为天线单元和接收单元两部分。接收机一般采用机内和机外两种直流电源。设置机内电源的目的在于更换外电源时不中断连续观测。在用机外电源时机内电池自动充电。关机后机内电池为RAM存储器供电,以防止数据丢失。目前各种类型的接受机体积越来越小,重量越来越轻,便于野外观测使用。其次则为使用者接收器,现有单频与双频两种,但由于价格因素,一般使用者所购买的多为单频接收器。
