How Does an FM Antenna Work?

FM Antenna

Imagine being able to send out music and thoughts through energy, electrons and radio waves. An FM antenna does just that. Antennas are sometimes called an aerial. You see antennas every single day of your life. They are built into our cell phones, our cars. Satellite dishes are even a form of an antenna. Antennas take on many forms, such as wires, rods, dishes and all manner of bizarre shapes, with the shape depending on exactly what is intended to be received or transmitted. The goal of an antenna is to send out radio waves throughout the earth, and even into space, or to receive data from long distances.

But how does an FM antenna work exactly? There are two types of antennas, one called a transmitter, the other more commonly seen type is a receiver. Both operate differently, yet in related ways. A transmitter generates electrical signals and turns them into radio waves, sending these radio waves through the transmitter at the speed of light. These radio waves can travel vast distances around the earth, and even into space. The further these waves travel, the more powerful the receiver must be.

A radio station uses an FM antenna to transmit songs, talk shows, programs and commercials across long distances. This data is turned into electrical energy, which surges along the FM antenna. While this process is ongoing, the signal or power is boosted. This energy has electrons in the electric current that surge back and forth across the length of the antenna to create electromagnetic radiation. This electromagnetic radiation is what you commonly call radio waves, and these radio waves travel  to transmit data at the speed of light. These radio waves are then captured by other receiver antennas. The radio waves captured by the listeners antenna surge along the receiver antenna, and this causes electrons to move, which in turn generates an electric current. A radio or other such device then converts this electric current into sound and data.

Anyone can buy an FM antenna and start their own radio station. All one needs is the right equipment and, of course an FCC license, which is not to terribly difficult to obtain.
