Antenna vs. Transmitter: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Updated on September 26, 2023
An antenna receives or sends electromagnetic waves, while a transmitter generates and sends them.

Key Differences

An antenna is a device designed to capture or broadcast electromagnetic waves. On the other hand, a transmitter is a device that produces and releases these electromagnetic waves.

The primary role of an antenna is to serve as an interface between electronic devices and free space, facilitating the sending or receiving of signals. Conversely, a transmitter functions by converting input information into electromagnetic waves suitable for broadcasting.

An antenna does not generate the signals it receives or transmits. Instead, it relies on a transmitter to generate the signal, which the antenna then broadcasts.

It is possible for systems to include both an antenna and a transmitter, as they often work in tandem. The transmitter produces the signal, and the antenna ensures it is appropriately broadcast or received.

Without a transmitter, an antenna would have no signals to send or receive. Similarly, without an antenna, the signals a transmitter generates would not effectively propagate through space.

Antenna

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.
