Conductors are an essential part of any electrical circuit. Their main role is the conversion of signals to waves. Additionally, they form an interlink of the transmitter, free space, and receiver. There are numerous types of conductors such as long periodic and wire transmitters. All these have specific characteristics which adopt them to their roles. Particularly, DAGR antenna has six varying features namely gain, directivity, aperture, polarization, effective length and polar diagram. Each of these has been described in details below.
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.
Apart from the gain, wavelength fields are polarized. Polarization describes orientation, as well as, the sensitivity of a wavelength field vector. Precisely, signals are elliptically polarized which means the total field of waves possesses two elements lying on a similar plane. However, these elements may vary in strength and angular disposition. Normally, the most prevalent forms of elliptical polarization are circular and linear. In circular divergence, components have equal magnitude but lie perpendicular to each other. Otherwise, there is only a single component.
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.
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.
Effective length is a feature which determines how well a projector sends and receives electromagnetic signals. It is defined as the ratio between the electromagnetic field at receiver end to intensity of projector electric field. That space is not occupied within a conductor as well as distribution of current across it creates an equal intensity within any radiation direction.
The radiation pattern for the transmitter describes radiation strength emitted from a conductor to various angular ways. It is represented in plots. Horizontal patterns are obtained if a plot is made on a parallel plane while vertical is obtained if the plot is on a perpendicular plane.
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.
