Antenna and Wave propogation

Lens Antenna

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 …

Types of Antenna Arrays

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 …
