Antenna vs. Feeler — What's the Difference?

A conductor by which electromagnetic waves are sent out or received.

An organ used for touching and feeling the surroundings.

Any set of conductors intended to radiate or receive radio waves.

A tactile organ on an insect used for sensing.

A device used for transmitting or receiving radio waves.

A structure on insects for chemical communication.

A means of transmission, often used metaphorically.

An antenna-like structure that provides sensory information.

A metallic apparatus designed to send or catch radio or TV signals.

A biological sensor used by various arthropods.

(Zoology) One of the paired, flexible, segmented sensory appendages on the head of an insect, myriapod, or crustacean functioning primarily as an organ of touch.

Something, such as a hint or question, designed to elicit the attitudes or intentions of others.

Something likened to this sensory appendage, as in function or form

(Zoology) A sensory or tactile organ, such as an antenna, tentacle, or barbel.

A structure in a photosynthetic organism containing pigment molecules that absorb light energy and transfer it to a reaction center composed of proteins and pigments, where the light energy is converted into chemical energy.

(literally) Someone or something that feels.

Pl. an·ten·nas A metallic apparatus for sending or receiving electromagnetic waves such as radio waves.

(anatomy) An antenna or appendage used for feeling, especially on an insect.

A feeler organ on the head of an insect, crab, or other animal. 17

(figuratively) Something ventured to test another's feelings, opinion, or position.

An apparatus to receive or transmit electromagnetic waves and convert respectively to or from an electrical signal.

(Philippines) Someone that assumes or imagines that one's affection is reciprocated; Someone that indulges in one's own wishful thinking; One who flatters oneself

(figurative) The faculty of intuitive astuteness.

One who, or that which, feels.

(biochemistry) A fragment of an oligosaccharide

One of the sense organs or certain animals (as insects), which are used in testing objects by touch and in searching for food; an antenna; a palp.

(nautical) The spar to which a lateen sail is attached, which is then hoisted up the mast.

Anything, as a proposal, observation, etc., put forth or thrown out in order to ascertain the views of others; something tentative.

A movable, articulated organ of sensation, attached to the heads of insects and Crustacea. There are two in the former, and usually four in the latter. They are used as organs of touch, and in some species of Crustacea the cavity of the ear is situated near the basal joint. In insects, they are popularly called horns, and also feelers. The term in also applied to similar organs on the heads of other arthropods and of annelids.

One of a pair of mobile appendages on the head of e.g. insects and crustaceans; typically sensitive to touch and taste

A metallic device, variously shaped, designed for the purpose of either transmitting or receiving radio waves, as for radio or television broadcasting, or for transmitting communication signals. Some types are: whip antenna, antenna tower, horn antenna, dish antenna, directional antenna and rabbit ears. See transmitter, receiver.

A tentative suggestion designed to elicit the reactions of others;

An electrical device that sends or receives radio or television signals

Sensitivity similar to that of a receptor organ;

Sensitivity similar to that of a receptor organ;

Slender tactile process on the jaws of a fish

One of a pair of mobile appendages on the head of e.g. insects and crustaceans; typically sensitive to touch and taste

Feelers help insects find food, navigate, avoid predators, and interact socially through sensory information.

Antennas can be both internal, as seen in smartphones, or external, as in satellite dishes or TV antennas.

The main function of an antenna is to transmit and receive electromagnetic waves for communication purposes.

Feelers serve as sensory organs that help insects sense their environment and communicate chemically with other insects.

Most insects have feelers, but the size, shape, and functionality can vary widely among different species.

Yes, antennas can be affected by weather conditions like rain, snow, and wind, which can impact their performance.

Common types include dipole, Yagi, parabolic, and patch antennas.

While primarily used for communication, antennas can also be used in applications like radar and space exploration.

Antennas are typically made from conductive materials like metal, including aluminum and copper.

Yes, in biological terms, feelers and antennae refer to the same sensory organs on insects and some arthropods.

Feelers adapt to a variety of environments, enabling insects to survive and thrive by being sensitive to specific stimuli crucial for their ecological niche.

Insects naturally maintain their feelers through grooming behaviors to keep them sensitive and functional.

Yes, antenna technology is continuously evolving with advancements in materials and design to improve efficiency and functionality in various applications.

The design of an antenna affects its gain, bandwidth, and overall efficiency, which in turn influence the quality and range of the communication it can support.

Feelers vary in shape, size, and sensitivity, often adapted specifically to the needs and environment of the species.
