Antenna vs. Transmitter — What's the Difference?

A structure that receives and emits radio waves.

A device generating and sending signals for broadcast.

A device converting electrical signals into electromagnetic waves and vice versa.

The origin of signals in a wireless setup.

(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.

An apparatus converting information into signals for transmission.

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

An electronic unit producing and modulating signals.

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.

In electronics and telecommunications a transmitter or radio transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna.

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

One that transmits

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

An electronic device that generates and amplifies a carrier wave, modulates it with a meaningful signal derived from speech or other sources, and radiates the resulting signal from an antenna.

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

The portion of a telephone that converts the incident sounds into electrical impulses that are conveyed to a remote receiver.

(figurative) The faculty of intuitive astuteness.

A telegraphic sending instrument.

(biochemistry) A fragment of an oligosaccharide

A neurotransmitter.

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

One who or that which transmits something (in all senses).

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.

An electronic device that generates and amplifies a carrier wave, modulates it with a meaningful signal derived from speech, music, TV or other sources, and broadcasts the resulting signal from an antenna.

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.

One who, or that which, transmits; specifically, that portion of a telegraphic or telephonic instrument by means of which a message is sent; - opposed to receiver.

An electrical device that sends or receives radio or television signals

Someone who transmits a message;

Sensitivity similar to that of a receptor organ;

Any agent (person or animal or microorganism) that carries and transmits a disease;

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

Set used to broadcast radio or tv signals

A metallic apparatus for sending or receiving electromagnetic waves.

A source of electromagnetic waves in a communication system.

A means to capture and propagate signals in a wireless system.

An elongated sensory appendage in insects and crustaceans.

An antenna's primary function is to radiate and receive electromagnetic waves.

A transmitter produces and modulates signals, preparing them for broadcast.

Larger antennas can offer better gain and directivity, making them more effective at capturing or radiating weak signals.

Yes, antennas are often designed for specific frequency bands to optimize performance.

Transmitters are powered by electrical sources, often using amplifiers to boost signal strength.

Antennas are usually made of conductive materials, most commonly metals like copper or aluminum.

For effective broadcasting, a transmitter typically requires an antenna.

A transmitter modulates signals by varying their amplitude, frequency, or phase based on the information being sent.

Transmitters connect to antennas using coaxial cables or other transmission lines.

An antenna needs a transmitter to provide the signals it radiates.

Yes, the location, orientation, and surrounding environment can significantly impact an antenna's reception.

Overheating can cause a transmitter to malfunction or even sustain permanent damage.

Yes, any device that communicates wirelessly requires both an antenna and a transmitter.

Yes, a transmitter's range can be limited by its power, frequency, and external interferences.

Yes, multiple antennas can be used in arrays to improve signal strength and directivity.
