# Electronic – How to make an impedance matched circuit for fabbed antenna

antennaimpedancematchingmicrowaveRF

Okay I have developed an antenna for a system and need to create an impedance matching circuit. The theory of conjugate matching is simple, but actually implementing it is something I can't find explained anywhere. For example, do I use the network analyzer to first find the real and imaginary impedance at a desired frequency with the smith chart, and THEN I can take S11 measurements?

I have access to a network analyzer and a spectrum analyzer. Please take me through the step-by-step process of creating an impedance matching circuit.

Calculate a value of parallel capacitance that gets you from 50 ohms (real) down to the real part of the antenna's impedance. $$\frac{1}{\frac{1}{50}+jwC}=R$$
