[รฆnหˆtษ›n.eษช ]

Definitions

Context #1 | Noun

biological structure

Antennae are sensory appendages found on the heads of many arthropods, such as insects, crustaceans, and myriapods. They are typically used for detecting environmental cues, such as chemicals, sounds, and vibrations. In insects, antennae can come in various shapes and sizes, each adapted for specific sensory functions. Antennae play a crucial role in the survival and interaction of these creatures within their habitats.

Synonyms

feelers, sensory organs.

Examples of usage

  • The butterfly moved its antennae to sense the air.
  • Crickets use their long antennae to detect predators.
  • Ants communicate using pheromones sensed by their antennae.
Context #2 | Noun

engineering

In engineering and telecommunications, antennae refer to devices used to transmit and receive electromagnetic waves. They play a critical role in radio, television, and wireless communication systems. Antennae can vary greatly in shape and size, used for different frequency ranges and applications.

Synonyms

receiver, transmitter.
