- sensitiveness similar to that of a receptor organ
- among a set of mobile appendages on head of e.g. insects and crustaceans; usually responsive to touch and taste
- an electric unit that sends or receives radio or television signals
- A movable, articulated organ of sensation, connected to the heads of pests and Crustacea. There are two inside previous, and frequently four in latter. These are generally used as organs of touch, and in some species of Crustacea the hole associated with the ear is found near the basal joint. In bugs, they've been popularly known as horns, and also feelers. The term in additionally placed on similar body organs in the minds of various other arthropods as well as annelids.
1640s, "feeler or horn of an insect," from Latin antenna "sail lawn," the long lawn that sticks on some sails, which is of not known beginning, maybe from PIE root *temp- "to stretch, extend." Inside etymological sense, it's a loan-translation of Aristotle's Greek keraiai "horns" (of bugs). Modern-day use within radio, etc., for "aerial wire" is from 1902.

Sometimes described as an aerial, an antenna is an electric unit familiar with transmit data. It accomplishes this by transforming electrical energy into electromagnetic, either micro or radio, waves. Antennas are employed in numerous devices eg cordless routers, tvs, Bluetooth allowed products, vehicle stereos, two-way radios, RFID tags, and garage home openers.
(n.) A movable, articulated organ of feeling, connected to the minds of bugs and Crustacea. There's two in the previous, and in most cases four into the latter.

The expression in additionally applied to comparable organs on minds of other arthropods as well as annelids.
All of them couple the transmitting antenna directly or inductively to a capacity-inductive circuit serving as a storage of energy, and all of them create thereby electric waves of the same type moving over the earth's surface with the magnetic force of the wave parallel to it.
