Video Analysis of Half-Wave Dipole Antennas. In this video, we go over the short-dipole antenna, the half-wave dipole antenna and the general dipole antenna. The idea is to give an intuitive overview of the first 3 antennas we've discussed.

Dipoles whose length is approximately half the wavelength of the signal are called half-wave dipoles and are widely used as such or as the basis for derivative antenna designs. These have a radiation resistance which is much greater, closer to the characteristic impedances of available transmission lines , and normally much larger than the ...
The length of the total wire, which is being used as a dipole, equals half of the wavelength (i.e., l = λ/2). Such an antenna is called as half-wave dipole antenna. This is the most widely used antenna because of its advantages. It is also known as Hertz antenna.
A half wave dipole antenna is an antenna constructed using a conductive tube or metallic element that has a length equal to the electrical half wavelength. The excitation to the half wave dipole is provided at the centre.
18 sie 2023 · The half wave dipole is not only one of the most simple and common antennas, but it also forms a basic building block for many other types. This is a common drawing of one: But that really isn’t too practical – you can’t get it perfectly horizontal when supported by ropes on the ends, as the weight of the wire and feedline will make it ...
The full-wavelength dipole antenna is more directional than the shorter quarter-wavelength dipole antenna. This is a typical result in antenna theory: it takes a larger antenna in general to increase directivity.
A more practical dipole is the half-wave dipole (referring to the fact that it is =2 long). The main reason for this, as we will see, is that the half-wave dipole has a real input impedance at resonance which is close to common system impedances.
