If you were asked to use one equation to explain antenna theory, which one would it be? Why?
a) Friis Transmission Equation, as it relates power, distance, and gains in antenna systems.
b) Maxwell's Equations, as they provide a fundamental understanding of electromagnetic behavior.
c) The Smith Chart equation, for impedance matching in transmission lines.
d) The Radar Range Equation, for estimating the maximum detection range of radar systems.
