The half-wave dipole antenna is discussed. This is a special case of the dipole antenna, and one of the most commonly used. The radiation pattern and basic properties (impedance, directivity) are presented along with plots, graphs of the radiation pattern.
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 ...
OW ELEVATION ANGLE(a in Fig, 6). Therefore, to judge antenna performance, it is more useful to have an antenna pattern showing the radiation at 30. egrees or more above the horizon. Figure 8 is a diagram showing the signal strength (represented by vectors) radiated from a typical half-wave dipole anten.
Antenna Theory - Half-Wave Dipole - The dipole antenna is cut and bent for effective radiation. The length of the total wire, which is being used as a dipole, equals half of the wavelength (i.e., l = λ/2).
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.
Half-wave dipole antennas are among the most common antenna topologies. They are simple to design and fabricate and offer a rotationally symmetric radiation ...
The type and design of the antenna is based on any number of parameters: specifically, the frequency or band of frequencies, location, directivity, and intended power range.
