The half structure for a regular dipole antenna is called a monopole antenna, in reference to the presence of only one physical side. A similar half structure for a folded dipole antenna is called a folded monopole antenna. The presence of the ground plane allows the monopole antenna to operate as electrically equivalent to a dipole antenna. The ground plane equivalently replaces the lower half by an imaging principle, similar to creating an optical image through a mirror. Notice i Antennas (Home) A monopole antenna is one half of a dipole antenna, almost always mounted above some sort of ground plane. The case of a monopole antenna of length L mounted above an infinite ground plane is shown in Figure 1 (a). Figure 1.

The quarter-wave monopole (0.25λ, blue) has a pattern identical to the upper half of a dipole antenna pattern. The half-wave monopole (0.5λ, green) radiates more of the power in horizontal directions. The maximum horizontal radiation for a monopole antenna is achieved at a length of 0.625λ (red). At lengths above a half wavelength (0.5λ) the radiation pattern divides into two lobes, with a second lobe directed into the sky.

. Jetzt bei A.T.U online bestellen Monopole antennas can be used in a range of frequencies from several hundred kHz to a few GHz. In telecommunications terminology, a monopole usually refers to an antenna that stands alone and is self-supported or guy-wire supported, meaning it's supported by the tension of attached cables which are anchored to the ground. A group of monopoles used to manage the direction of long and medium. Monopole antennas operating at VLF and LF ranges are short compared to a wavelength and have a low radiation resistance. Their efficiency can be improved by adding a horizontal wire at the top, as shown in Figure 9.12. Due to the top loading, the current in the vertical part is increased. The fields produced by the vertical part and its image add constructively. However, the fields from the horizontal part and its image cancel each other, because their currents flow to opposite.
Alternatively, printed monopole antennas can be seen as a vertical monopole antenna. A monopole antenna usually consists of a vertical cylindrical wire mounted over the ground plane, whose bandwidth increases with increase in its diameter. A printed monopole antenna can be equated to a cylindrical monopole antenna with large effective diameter. monopole antenna and its family. The monopole antennas are convenient to match to 50 ohms, and are unbalanced. This eliminates the need for a balun, which may have a limited bandwidth (BW).

Below is the output result of a NEC4.2 analysis of an electrically short monopole, showing its near-field boundary radius to be located about 30 meters from the base of that monopole. The groundwave field beyond about 30 meters decays at nearly a 1/r rate, but not exactly 1/r because of the surface wave propagation losses present for these conditions — even for the short path shown 2 Meter Monopole vs J-Pole Antenna. In the left side of the ring we have the classic 1/4 wave monopole antenna with four drooping radials. On the right we have at a full 3/4 total wave in height the j-pole antenna. These two antenna models are based on Cebik's antenna collection available from his web site. If you would like to simulate these and hundreds more antenna models, seriously. Monopole antenna is the simplest form of antenna, which is basically just a piece of un-shielded wire. It's very common in radio receivers because they are cheap and easy to repair. However they are not as effective as Dipole antennas. The length of the exposed wire is crucial as it determines the resonant frequency (frequency that it can pick up).
