This calculator analyzes a complex impedance of the form: $$Z=R+jX$$ Where:

• R is the resistive (real) component
• X is the reactive (imaginary) component

It calculates:

• Magnitude: $|Z|=\sqrt{R^2+X^2}$
• Phase Angle: $\theta ={\tan }^{-1}(X/R)$
• Polar Form: $|Z|\mathrm{\angle }{\theta }^{\circ }$
• Admittance: $Y=1/Z=\frac{1}{|Z|}\mathrm{\angle }-\theta$

Useful in RF system analysis, transmission line matching, Smith chart plotting, and network design.
