What does Antenne mean?
1 plural antennae : one of a pair of slender, movable, segmented sensory organs on the head of insects, myriapods, and crustaceans — see insect illustration. 2 : a usually metallic device (such as a rod or wire) for radiating or receiving radio waves a TV antenna.
What is the meaning of antennae in science?
Antennae (singular: antenna), sometimes referred to as “feelers”, are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
What are insect antennae?
The antennae are a pair of sense organs located near the front of an insect’s head capsule. They are usually covered with olfactory receptors that can detect odor molecules in the air (the sense of smell). Many insects also use their antennae as humidity sensors, to detect changes in the concentration of water vapor.
What is an antenna in simple words?
An antenna or aerial is a metal device made to send or receive radio waves. Antennas work both in air and outer space. The word ‘antenna’ is from Guglielmo Marconi’s test with wireless equipment in 1895.
Is antenna an American word?
antenna | American Dictionary either of the two long, thin parts attached to the head of an insect that it uses to know what is around it: fig. Her political antennae helped her answer questions without offending anyone.
What is the purpose of antennae?
The primary function of antennae is the assessment of the chemical and physical characteristics of the environment. Detection is made with innervated chemosensory and mechanosensory organs that are arrayed on the antennae. A single antenna usually has sensory organs of several types, with different properties.
What do cockroaches use their antennae for?
Cockroach antennae have been extensively used for studying the multifunctional sensory appendage that generates the olfactory, gustatory, tactile, thermal, and humidity senses. In addition, the motor function of antenna also contributes to the active tactile sense (Staudacher et al. 2005; Comer and Baba 2011).
What are antennae used for?
Do all insects have 2 antenna?
Nearly all insects have a pair of antennae on their heads. They use their antennae to touch and smell the world around them. Insects have six legs that are attached to the middle section of the body, the thorax.
What is an antenna and what does it mean?
Definition – What does Antenna mean? An antenna is a transducer that converts radio frequency (RF) fields into alternating current or vice versa. There are both receiving and transmission antennas for sending or receiving radio transmissions.
What are the names of the different types of antennas?
1 Short Dipole Antenna 2 Dipole Antenna 3 Loop Antenna 4 Monopole Antenna
What makes the electrical properties of an antenna the same?
The electromagnetic reciprocity theorem guarantees that the electrical properties of an antenna, such as efficiency, directivity, and gain, are the same when the antenna is used for receiving as when it is transmitting.
What kind of antenna has an opening in the surface?
A class of directional antennas, Aperture Antennas have an opening in the surface. Usually, aperture antenna consists of Dipole or Loop Antenna in a guiding structure with an opening to emit radio waves.
What does the name antennae mean?
Antennae meaning Filters (0) The definition of antennae are wires that receive and conduct electromagnetic waves, typically to transmit information.
What are the antennae used for?
Antennae (singular: antenna), sometimes referred to as “feelers”, are paired appendages used for sensing in arthropods . Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
What’s the plural of antenna?
The plural of antenna is antennas or antennae . Antennas are used for sensing in arthropods . Crustaceans bear two pairs of antennae. The noun antenna has a Latin root, which is the derivation of the plural antennae. Through common usage, antennas (which adheres to the standard rules for forming plurals)…
What is a transmit antenna?
A transmitter is a different kind of antenna that does the opposite job to a receiver: it turns electrical signals into radio waves so they can travel sometimes thousands of kilometers around the Earth or even into space and back. Antennas and transmitters are the key to virtually all forms of modern telecommunication.
