DIRECTIONAL ANTENNA Meaning and
Definition
-
A directional antenna is a type of antenna that focuses its radiation pattern in a specific direction to enhance signal reception or transmission in that particular direction. It is designed to increase the gain or radiation intensity in a specific direction and reduce radiation or sensitivity in other directions.
Directional antennas are commonly used in various applications, including wireless communication systems, broadcasting, remote sensing, and radar systems. They can be employed to establish long-distance communication links, improve signal strength, and minimize interference.
These antennas typically consist of multiple elements or arrays that work together to form a concentrated beam pattern. They can be classified into several types, such as Yagi-Uda antennas, parabolic reflector antennas, panel antennas, or horn antennas, each with its own unique design and characteristics.
The primary advantage of a directional antenna is its ability to provide higher gain or sensitivity in a specific direction, which enables increased signal strength and range. This allows for the establishment of longer communication links and improved signal quality. Additionally, the directional nature of these antennas helps to reduce interference from unwanted signals originating from other directions, resulting in improved signal reception and reduced noise.
Overall, directional antennas play a vital role in enhancing wireless communication systems and are widely utilized in various industries where targeted signal transmission or reception is required.

Etymology of DIRECTIONAL ANTENNA
The word "directional" comes from the Latin word "directiōnālis", which is derived from the verb "dirigere", meaning "to direct" or "to guide". "Antenna" has its roots in the Latin word "antenna", which referred to the sail yard of a ship. This term was later used to describe the metallic wires or rods used in wireless communication systems. Thus, "directional antenna" combines these elements to convey an antenna that is able to transmit or receive signals in a specific direction.
