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.

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 …
A long wire antenna is a type of antenna in which the length of the wire is usually greater than the length of the half-wave dipole i.e., λ/2. These are also known as harmonic antennas. It offers operating frequency range between 500 kHz to 30 MHz. Content: Long Wire Antenna Introduction Construction Working Radiation Pattern …
Definition: Helical antenna is a type of antenna that is designed using conducting wire and is constructed in the shape of a helix. These antennas are considered as one of the simplest antennas and are widely used in very high and ultra-high frequency operations. So, finds applications in extraterrestrial communication like satellite relays etc. The …
Definition: Horn antenna is a type of antenna which is constructed when the end of the antenna is flared out or tapered in the shape of a horn. Horn antenna operates in microwave frequency. These operate in ultra-high and super-high frequencies ranging between 300 MHz to 30 GHz. It is generally considered as a waveguide …
Definition: The type of antenna which is formed by connecting long wires in the orientation of a rhombus is known as a rhombic antenna. Its basis of operation is similar to travelling wave radiator. It is also known as a diamond antenna. These are highly directional broadband antenna that radiates maximal power along the axis. …
Definition: An antenna that is formed by etching out a patch of conductive material on a dielectric surface is known as a patch antenna. The dielectric material is mounted on a ground plane, where the ground plane supports the whole structure. Also, the excitation to the antenna is provided using feed lines connected through the …
Definition: A type of antenna with an opening cut of certain dimensions in a metallic conductor which is excited using a two-wire transmission line or coaxial cable is known as a slot antenna. These antennas operate in the frequency ranging between 300 MHz to 30 GHz. It is generally formed by making an elongated slot …
