Antenna Pattern Measurement is a way of determining the radiation pattern of the antenna under test i.e., AUT. Antenna pattern or radiation pattern graphically represents the radiation properties of the antenna with respect to the space coordinates. For the measurement of antenna pattern more specifically, it can be said that it refers to the measurement …
Antenna measurement is regarded as a crucial aspect of antenna designing. This is so because while designing the antenna, antenna measurement is performed at different levels that lead to help in checking whether the desired specifications have met or not. It involves a method where the source antenna (either transmitting or receiving) is placed at …
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 …
