Matching Circuit Optimization for Antenna Applications

Impedance matching

Impedance matching is an essential part of antenna design. The input impedance of an antenna needs to be reasonably close to the amplifier impedance (e.g. 50 Ohm), otherwise the signal is reflected back to the amplifier and not radiated by the antenna. In many applications, matching circuits consisting of discrete inductors and capacitors, or transmission lines are used to improve the impedance matching characteristics of the antenna.
