ARRAY GAIN Meaning and Definition

  1. Array gain refers to the increase in signal strength or power achieved by using an array of multiple antennas or elements instead of a single antenna. It is a measurement of the system's ability to enhance the received signal power by combining the signals from multiple antennas or elements.

    When multiple antennas or elements are spatially positioned in an array, they can capture the incoming waves of a signal from different angles and paths. This allows for diversity and spatial processing, resulting in a combined and coherent signal that has a higher gain than a single antenna setup. The array gain is the ratio of the power received by an antenna array to the power received by a single antenna operating under the same conditions.

    The array gain depends on factors such as the spacing and orientation of the antennas or elements within the array, their gain patterns, and the specific signal propagation characteristics. By leveraging the diversity and spatial processing capabilities of an antenna array, array gain helps improve the received signal quality, increase the system's signal-to-noise ratio, and enhance overall system performance.

    Array gain is commonly utilized in various fields, including wireless communication systems, radar systems, and radio astronomy, where the use of multiple antennas helps combat fading, interference, and other detrimental effects in signal transmission and reception.

Etymology of ARRAY GAIN

The term "array gain" is a combination of two words: "array" and "gain".

1. Array: The word "array" is derived from the Middle English word "arayen", which means "to put in order". It is also related to the Old French word "arrayer" and the Latin word "ad" (meaning "to") + "radere" (meaning "to scrape" or "scratch"). Over time, the meaning of "array" evolved to refer to an ordered arrangement or formation of objects.

2. Gain: The word "gain" is derived from the Old French word "gaignier", which means "to earn" or "to win". It can be traced back to the Late Latin word "ganare" or "gagnare", with similar meanings. The concept of gain involves the acquisition of something, often referring to an increase in wealth, possessions, or advantage.
