folded dipole

偶极天线

Dipole antenna

在无线电和电信领域,偶极天线或双极天线是最简单和最广泛使用的天线类。 它由两个相同的导电元件(例如金属线或棒)组成,通常是双边对称的。 应用来自发射机的驱动电流,或者对于接收天线,在天线的两半之间采集到接收机的输出信号。 馈线的发射器或接收器的每一侧都连接到导体之一。 这与单极天线形成对比,单极天线由单根杆或导体组成,其中馈线的一侧与其连接,另一侧连接到某种类型的地面。 偶极子的一个常见例子是在广播电视机上发现的“兔耳”电视天线。 偶极子最常见的形式是在相同轴线上端对端定向的两根直线或导线,馈线连接到两个相邻端。 从理论的角度来看,这是最简单的天线。 偶极子是谐振天线,意味着这些元件用作谐振器,无线电电流的驻波在它们的端部之间来回流动。 In radio and telecommunications a dipole antenna or doublet is the simplest and most widely used class of antenna. It consists of two identical conductive elements such as metal wires or rods, which are usually bilaterally symmetrical. The driving current from the transmitter is applied, or for receiving antennas the output signal to the receiver is taken, between the two halves of the antenna. Each side of the feedline to the transmitter or receiver is connected to one of the conductors. This contrasts with a monopole antenna, which consists of a single rod or conductor with one side of the feedline connected to it, and the other side connected to some type of ground. A common example of a dipole is the "rabbit ears" television antenna found on broadcast television sets. The most common form of dipole is two straight rods or wires oriented end to end on the same axis, with the feedline connected to the two adjacent ends. This is the simplest type of antenna from a theoretical point of view. Dipoles are resonant antennas, meaning that the elements serve as resonators, with standing waves of radio current flowing back and forth between their ends.

在英语 词典里folded dipole的定义

字典中折叠偶极子的定义是一种天线,广泛用于电视和VHF无线电接收机,由两个平行的偶极子组成,它们的外端连接在一起,并馈送在其中一个偶极子的中心。 长度通常是工作波长的一半。

The definition of folded dipole in the dictionary is a type of aerial, widely used with television and VHF radio receivers, consisting of two parallel dipoles connected together at their outer ends and fed at the centre of one of them. The length is usually half the operating wavelength.
