direzionali

Direzionali is the plural form of direzionale in Italian, meaning directional or oriented toward a particular direction. It functions as an adjective and, in some technical contexts, as a noun to describe devices, patterns, or responses that exhibit directional selectivity.

In engineering and technology, direzionali elements are designed to respond preferentially to signals arriving from a specific direction while suppressing others. In telecommunications, direzionali antennas focus energy in chosen directions to increase range or reduce interference; common examples include Yagi-Uda antennas, parabolic dishes, and horn antennas. In acoustics, direzionali microphones such as cardioid, supercardioid, and shotgun patterns capture sound from a targeted area while rejecting noise from the sides and rear.

The term also applies to other transducers and sensing systems whose output depends on the direction of the incoming signal, including certain optical and radio-frequency devices. The concept of directionality is central to fields like antenna theory, radar and sonar, acoustics, and directional drilling.

Etymology: Direzionali derives from the Italian direzione (direction) with the suffix -ale, matching the English term directional.
