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 …
Antenna Array is defined as a radiating element formed by arranging various individual antennas in properly spaced and phased manner. An antenna array acts as a single element that which is used to transmit and receive RF waves. The various individual antennas that are configured to form an antenna array are known as elements. Content: …
A type of antenna in which the length of the dipole is half the wavelength at the operating frequency is known as a half wave dipole antenna. It is considered as a very popular form of a dipole antenna and is sometimes known as Hertz antenna. Generally, it is known to be the one with …
Yagi-Uda Antenna is an antenna that is well known for its high gain and directivity. A Yagi-Uda antenna is formed by a combination of 3 major elements i.e., driven element, reflector and directors. These are basically designed to operate in very high and ultra-high frequency bands and offers the operating frequency ranging between 30 MHz …
