S11 to reflected power
WebS11 represents how much power is reflected from the antenna, and hence is known as the reflection coefficient (sometimes written as gamma: or return loss. If S11=0 dB, then all the power is reflected from the antenna and nothing is radiated. If S11=-10 dB, this implies that if 3 dB of power is delivered to the antenna, -7 dB is the reflected power. WebThe ratio of a sinusoidal signal reflected back from the load to the formward signal absorbed by the load in dB is called return loss. The term ‘forward power is synonymous …

WebMay 7, 2024 · S11 and return loss are closely related; the two quantities are reciprocals of each other. Most RF designers are familiar with the formula for return loss: Definition of return loss in terms of transmission line reflection coefficient. The input impedance and S11 (return loss) are both related to the transmission line reflection coefficient.
