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.
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.
Apart from the above parameters, all electrodes transmit a certain frequency range and direction. Precisely, these features are known as bandwidth and directivity respectively. Notably, the directive of an electrode quantifies the concentration of radiated power in a given direction. Waves are strongest where concentration is higher. Differently, directivity is the ability of a conductor to radiate power in a specific direction. Else, it may be defined as the ratio between power intensity within a certain concentration point to average power strength.
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.
There are six parameters used to describe conductors. These are a polar diagram, gain, bandwidth, directivity among others. If purchasing a device, they should fulfill these features as described above.
