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 ...
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.
Learn about the construction, working, radiation pattern, advantages, disadvantages and applications of half wave dipole antenna. It is a simple and popular form of dipole antenna with a length equal to half the wavelength at the operating frequency.
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.
Learn how a half-wave dipole antenna is constructed, how it radiates, and how it differs from a Hertzian dipole. Find the input impedance, the radiation pattern, and the ohmic loss of a half-wave dipole at resonance and off-resonance.
antenna is based on any number of parameters: specifically, the frequency or band of frequencies, location, directivity, and intended power range. This paper discusses some of the more important aspects of the End Fed Half Wave (EFHW) dipole antenna. The frequency band is HF (40 meters), and the intended power is 100 watts.
