Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency [1] range from around 20 kHz to around 300 GHz.

In this guide, we will explore how RF systems behave in real-world applications, the tools you need to tackle common RF problems, and practical techniques to achieve better results.
Radio frequency (RF, rf) measures electromagnetic radio waves, and using antennas and transmitters, it can be used for wireless broadcasting and communications.
“RF” refers to the use of electromagnetic radiation for transferring information between two circuits that have no direct electrical connection. Time-varying voltages and currents generate electromagnetic energy that propagates in the form of waves.
RF stands for Radio Frequency, and an RF signal refers to an electromagnetic wave used to transmit information wirelessly. These signals typically fall within the frequency range of 3 kHz to 300 GHz.
RF energy is transmitted and received using antennas. When an electric current moves through an antenna, it creates electromagnetic waves that propagate through space.
They propagate by ground waves, skywaves, and line-of-sight. Principal uses include broadcasting, mobile telephony, Wi-Fi, radar, satellite links, radio astronomy, RFID, and remote controls. Radio-frequency (RF) exposure is safe within regulated limits. While non-ionizing, RF wave produce heating.
Radio Frequency (RF) is the lowest portion of the electromagnetic spectrum and is familiar as a medium of analog and modern digital wireless communication systems. It spreads between 3 kHz and 300 GHz.
