The Origins of RF Waves

The Origins of RF Waves

Radio frequency (RF) waves are a type of electromagnetic radiation that have been used for communication and other applications for over a century. They were first discovered by Heinrich Hertz in the late 19th century during his experiments with electrical circuits. Hertz’s work laid the foundation for the development of wireless communication technologies that are still in use today.

RF waves are produced by oscillating electric currents in antennas, which create electromagnetic fields that can travel through the air or space. These waves have a wide range of frequencies, from a few kilohertz to hundreds of gigahertz, and are used in various applications such as radio broadcasting, television transmission, radar systems, and wireless communication technologies like Wi-Fi and Bluetooth.
