Essentially, the properties of conductors are an important part of the modern day wireless communication. Conductors are components that convert electric signals to electric-magnetic waves. To perform this responsibility effectively, transmitters have specific features. Specifically, DAGR antenna has six properties. Below paragraphs expound on each.
Essentially, the general performance of a transmitter is described through a feature referred to as the gain. The gain is related to directivity in that for a perfect transmitter, they are equal. This is not usually the case for a number of reasons. The efficiency is affected by the type of material making up electrodes. If metallic, rather than radiating entire waves at the output, some energy is lost along conducting device. Ultimately, radiated waves are weaker at receiving end. Similarly, for a perfect gain, the impedance of rods should match that of a connecting line. If this does not happen, some energy is radiated back to the sender which affects transmitter gain. Additionally, to protect a radiating component, it is housed within a radome. Just as a conducting element, radomes dissipate some energy affecting the overall quality of radiated waves.
Another feature is polarization. The divergence is described as alignment and sense of a radiated current vector line. Waves are polarized either vertically or horizontally. If divergence occurs vertically, E vector is equally vertical thus needs a vertical transmitter. Conversely, horizontal divergence requires a horizontal transmitter for launching to take place. A different type of polarization is circular whereby horizontal as well as vertical ways are launched together.
Another parameter is aperture. Also known as the effective aperture of an electrode, it actively takes part in sending as well as receiving electromagnetic signals. It can be described as a joint area linked to a conductor where all power emanates.
Directivity, as well as, bandwidth is another aspect. Power is usually concentrated in a specific direction. Directivity measures this to ascertain where more radiation is taking place. Additionally, directivity may be described as the ability of transmitters to direct radiations in a specific direction. On the other hand, bandwidth is a variety of frequencies over which transfer of radiated current can take place. While choosing a projector, bandwidth is an important aspect to consider. If it has a wide range of frequencies capability, then it is more efficient.
Another aspect of projectors tells how efficient a transmitter is in sending and receiving current. It is determined by a factor called effective length. For sending devices, the effective length is the ratio of current field at receiver input to signal strength at a transmitter end. For receiving components, the effective length may be used to describe the free area within, as well as, the distribution of energy across a conducting device. Normally, this generates an equal electromagnetic field strength in all radiation directions.
Most importantly is polar diagram characteristic. Also, referred to as radiation pattern, it is a reflector of the strength of an electromagnetic wave field. More concentrated field means that electromagnetic field is stronger. Waves may form either horizontal or vertical patterns.
The sections illustrate various features of projectors. These define alignment as well as magnetic field strengths. The above aspects are some of the parameters of this antenna.
