An Air capacitor definition is a capacitor that uses air as the dielectric medium. This capacitor can be designed in a fixed or variable capacitance form.
The simplest air capacitors are made of two conductive plates separated by an air gap. Air capacitors can be made in a variable or fixed capacitance form. Fixed capacitance air capacitors are rarely used since there are many other types with superior characteristics. Variable air capacitors are used more often because of their simple construction.

Variable air capacitors are used more often because of their simple construction. They are usually made of two sets of semicircular metal plates separated by air gaps.
Air capacitors are generally made with two sets of semicircular metal plates which are separated through an air dielectric material. In these metal plates, one set is permanent & the other set is connected to a shaft which allows the operator to turn the assembly to change the capacitance when required.

Air variable capacitors are used to tune L-C resonant circuits found in radio frequency power amplifiers. They are also found in antenna impedance matching networks. Their simple design offers high voltage ratings, low leakage and a high quality factor (Q). Air variable capacitors are non-polarized.
