ANTENNA ARRAY Meaning and
Definition
-
An antenna array refers to an assemblage of multiple antennas that are arranged together to work collectively and collaboratively in a specific configuration. It is commonly utilized in various fields, such as wireless communications, radar systems, and radio astronomy. The primary purpose of an antenna array is to enhance the desired signal reception or transmission characteristics, including improved signal strength and increased directivity.
The configuration of an antenna array can vary depending on the specific requirements of the application. It can consist of a linear arrangement of antennas, often referred to as a linear array, where antennas are placed in a straight line. Another common configuration is a rectangular arrangement of antennas, called a planar array, where antennas are positioned in a two-dimensional grid. Additionally, advanced configurations such as circular, spherical, or conformal arrays are employed for specialized applications.
Antenna arrays are designed in a manner that enables constructive interference, meaning the signals from individual antennas combine coherently to strengthen the desired signal while minimizing interference. This result is achieved through careful control of the antenna element spacing, phase, and amplitude distributions. As a consequence of constructive interference, antenna arrays can provide improved signal reception, greater resolution for radar systems, and increased array gain.
In summary, an antenna array is an assemblage of multiple antennas configured in a specific arrangement to collaborate and achieve enhanced signal reception or transmission characteristics, such as improved strength and directivity.

Etymology of ANTENNA ARRAY
The etymology of the phrase "antenna array" can be explained as follows:
1. Antenna: The word "antenna" comes from the Latin word "antenna", which means "sail yard" or "pole". In ancient times, the word was used to refer to the mast or pole on sailing ships. Over time, it started to be used to describe the wire or device used for sending and receiving radio waves.
2. Array: The word "array" originated from the Latin word "arredare", which means "to arrange". It evolved through Old French and Middle English to refer to a systematic arrangement or display of things. In the context of technology, an array refers to an ordered arrangement or collection of similar objects or components.
Therefore, the term "antenna array" refers to a systematic arrangement of multiple antennas, typically used in telecommunications and radar systems.
