Definition: Radio Frequency (RF)

Radio frequency (RF) is any of the electromagnetic wave frequencies that lie in the extent stretching out from around 3 kHz to 300 GHz, which incorporate those frequencies utilized for communications or radar signals. RF more often than not refers to electrical as opposed to mechanical motions or oscillations. Then again, mechanical RF frameworks do exist.

Although radio frequency is a rate of oscillation, the expression "radio frequency" or its abbreviation "RF" are utilized as an equivalent word for radio – i.e., to portray the utilization of wireless communication, instead of correspondence by means of electric wires.

The properties of RFs are as follows:

• The energy of an RF current can radiate a conductor as electromagnetic waves in to space. This is the property that is basically used in radio technology.

• RF currents have skin effect. They do not go deep into electrical conductors but flow along their surfaces. This is the reason that when human body comes in contact with high power RF currents it causes superficial and serious burns known as RF/ Radiation burns.

• RF currents do not cause electric shock in the human body as they change their direction too quickly and do not trigger depolarization of membranes of nerves.

• RF currents get reflected from discontinuities of cables. This is the reason that they are not transmitted through ordinary cables. They are always carried through special type of cables called transmission lines.


Hence, this concludes the definition of Radio Frequency (RF) along with its overview.
