What is a monopol antenna?

The monopoly antenna is a radio antenna that is half the dipole antenna combined with a right ground plane of considerable length instead of its second half. The dipole antenna has two halves, while the antenna monopole replaces one half of the electrically conductive surface known as the ground plane that behaves like the other half of the dipole antenna. With a sufficiently large ground plane, the monopoly antenna can be as strong as the dipole antenna. Automobile antennas are an ordinary example of a monopol antenna, with the metal of the car itself forming a basic plane.

There are two basic types of monopol antennas: solid and flat. The solid type, although it is more expensive to produce, is known to have a good bandwidth and is completely omnidirectional. The more frequently used and cheaper type of flat type also has a good bandwidth, but experiences distortion at higher frequencies, which is omni-directional. Cross -shaped, flat type of antenna monopole has been designed and implemented in recent years that overcomes this distortThe frequency and at the same time retain a good bandwidth. It was also made and tested in an effort to even further reduce frequency distortion with a dual frequency cross shape.

monopoly antennas can be used in a number of frequencies from several hundred kHz to several GHz. In telecommunication terminology, the monopoly usually applies to an antenna that stands alone and is supported separately or is supported, which means that it is supported by the voltage of the connected cables that are anchored to the ground. The group of monopol antennas used to control the direction of radio frequencies with long and medium wavelengths is called directional antenna fields.

antennas are used to transmit and receive electromagnetic waves that are converted from electric current or to electric current. This can be used for transmission or receiving, because the electromagnetic properties of all antennas are identical. Because antennasThey usually use radio waves to transmit and receive radio waves, are considered a key part of the radio.

antennas are used not only in television and radio broadcasting, but also in Point-to-Point communication. Mobile phones, wireless networks of local areas (LAN), spacecraft communication and radar require antennas to operate. Low costs and fast installation of monopol antennas made them the first choice for mobile and internet networks around the world, especially in developing countries.
