Oct 25, 2020 · A dipole antenna, also called a doublet or dipole aerial, consists of two conductive elements like rods or wires. This antenna type emits a radiation pattern similar to an elementary electric dipole, making it both simple and widely used.
Dipole antennas (or such designs derived from them, including the monopole) are used to feed more elaborate directional antennas such as a horn antenna, parabolic reflector, or corner reflector. Engineers analyze vertical (or other monopole) antennas on the basis of dipole antennas of which they are one half.
A dipole antenna is a type of RF antenna that includes two conductive elements like wires or rods where the metal wire length is half of the highest wavelength approximately in free space at the operation of frequency. At the center of the antenna, the conductive materials are separated through an insulator which is called an antenna section.
The dipole antenna is similar to the short dipole except it is not required to be small compared to the wavelength (at the frequency the antenna is operating at). For a dipole antenna of length L oriented along the z-axis and centered at z=0, the current flows in the z-direction with amplitude which closely follows the following function:
The Short dipole is the dipole antenna having the length of its wire shorter than the wavelength. A voltage source is connected at one end while a dipole shape is made, i.e., the lines are terminated at the other end.
The dipole and the monopole are arguably the two most widely used antennas across the UHF, VHF and lower-microwave bands. Arrays of dipoles are commonly used as base-station antennas in land-mobile systems. The monopole and its variations are common in portable equipment, such as cellular telephones, cordless telephones, automobiles, trains, etc.
5 days ago · Our dipole calculator is a simple tool that allows you to compute the length of a simple antenna — it'll also provide you with the value of the wavelength and the adjustment factor [k].
Aug 25, 2023 · The term dipole means “Two poles” and it contains two similar elements like wire or rods. The length of a metal wire is about half of the maximum wavelength. In the center of the dipole antenna,...
Aug 18, 2023 · The dipole antenna is one of the most elemental types. It not only makes a simple and effective antenna on its own, but it also forms a basic building block for many other types of antennas. First, let’s start with some definitions of the terms we will use.
A dipole is a balanced antenna, meaning that the "poles" are symmetrical: They're equal lengths and extend in oppo- site directions from the feed point. In its simplest form, a dipole is an antenna made of wire and fed at its center as shown in Fig 1.
