The Properties Of DAGR Antenna

By Charles Hill


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.

The first characteristic is the gain. This is defined as how efficient a projection is. The efficiency is affected by a number of factors. First, there is material making up conducting device. It can either be made of metallic or non-metallic substance. Second is radome losses. To protect conductors from environmental factors, radomes are fitted inside. Just like outside casing, radomes dissipate some heat energy rather than radiating which reduces overall efficiency. The last factor is the impedance. If it does not match with that of the transmission line, some waves directed towards the source are generated. As a result, the energy level transferred reduces.

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.

A variant feature is an aperture. This is a transmission throughway which allows effective transfer and reception of electromagnetic signals. Precisely, each signal received by a conductor is related to a collective space. That space is what makes an effective aperture.

Wavelength fields are concentrated in a particular direction at any given time. This aspect is described as directivity. Waves are stronger in the direction where concentration is more. In other cases, directivity could mean how possible it is for a conductor to send signals towards a given direction. Conversely, bandwidth is one aspect which should be considered while purchasing a projector. The range of frequencies over which conduction occurs is bandwidth. Definitely, the best projectors accept a wide range of frequencies.

A variant parameter is an effective length. It is a determinant of how effective a conductor is in transmitting or accepting electromagnetic signals. This definition holds for a receiving and sending transmitter. An effective length for the receiving rod is the ratio of waves at accepting terminal to overall field intensity. For a transmitter, it is the free space length within a transmitting component, as well as, the distribution of current across.

Radiation pattern explains how radiated energy is directed by a transmitter. Usually, in an ideal situation, the amount of energy radiated is equivalent to input power. Patterns radiated in various angular directions are presented in form of a plot or polar diagram. It is possible to plot for vertical, as well as, horizontal planes. Plots on perpendicular planes are called vertical patterns. Conversely, parallel plots bring about horizontal patterns.

There are six features of conductors. Briefly, they are the gain, aperture, direction and bandwidth, polarization, effective length, as well as, polar diagram. Most important aspect is radiation pattern which tells how strong a wave field is.
