Introduction of impedance matching

Impedance matching is mainly used on the transmission line to achieve the purpose that all high-frequency microwave signals can be transmitted to the load point, and almost no signal is reflected back to the source point, thereby improving energy efficiency. The internal resistance of the signal source is equal to the characteristic impedance of the connected transmission line and the phase is the same, or the characteristic impedance of the transmission line is equal to the magnitude of the connected load impedance and the phase is the same, respectively, and the input or output end of the transmission line is in an impedance matching state, which is simply referred to as Impedance matching.
