Definition: Antenna Polarization is the term used in correspondence with the electromagnetic wave radiated through it. It is defined as the orientation of the electric field vector of the radiated electromagnetic wave by the antenna with a negligible amount of losses. Polarization of the antenna is regarded as a crucial parameter and must be considered …
Definition: Antenna apertures are used in reference to the area of the antenna. It is defined as the measure of the ability of the antenna to effectively receive the power radiated towards it. As the term is associated with the area of the antenna, thus, shows the power capturing characteristics of receiving antennas. The aperture …
Antenna gain is associated with the ability of the antenna or antenna system to direct the radiated power in a specific direction or conversely, absorb the power efficiently coming from a particular direction. Gain is regarded as the fundamental quantity of antenna as it relates to the efficiency of the antenna system. The gain of the …
Definition: A type of antenna that is designed to collimate the incident divergent energy in order to convert it into plane waves using proper lens material is known as Lens Antenna. It is a microwave antenna that uses the principle of refraction utilized by the optical lens for light in order to re-radiate the received …
A type of reflector consisting of either two or three flat sheets that are conductive in nature, intersecting at 90° forming a corner, that allows the reflection of incoming waves is known as a Corner Reflector. The type of reflecting sheets that form corner offers high directive gain thus highly facilitates its use in antenna …
A type of reflector which has a reflecting surface having the shape of a paraboloid that is used to collect and re-radiated the electromagnetic energy is known as Parabolic Reflector. It is regarded as the simplest and popular form of reflector antenna. These are known as microwave antennas as exhibit a wide range of use …
Antennas that are designed to reflect the incident electromagnetic waves originating from a separate source are known as reflector antennas. It is designed to operate at high microwave frequency. These antennas belong to the category that offers high directionality while radiating. Content: Reflector Antennas Introduction Operating Principle Types of Reflector Applications Introduction Reflector antennas hold …
Definition: A broadband antenna that is designed to provide such electrical characteristics that vary repeatedly in a periodic manner with logarithmic of the frequency of operation is known as Log Periodic Antenna. This means in this antenna; the impedance and radiation pattern are the factors that are logarithm function of the frequency. The range of …
Definition: V antenna is a type of long wire antenna whose structure is designed in the form of a V. This is the reason it is given the name V antenna. It operates in the high-frequency range between 3 to 30 MHz. Basically, it is said to be an enhanced version of a long wire …
Previously we have discussed antenna array under various sections including its need, working, advantages, limitations along with applications. We know that an antenna array is a single system formed by arranging various antennas in an appropriate manner. Basically, proper spacing and proper phase must be provided to the antennas when configured as an array. Whenever …
