# What is s11 parameters

Scattering parameters or S-parameters describe the electrical behavior of linear electrical networks when. S-parameters for an antenna are introduced. S11 is known as the return loss, or how much power is reflected from the transmitter to an antenna. S21 or S S-parameters are usually displayed in a matrix format, with the number of rows and columns equal to the number of ports. For the S-parameter Sij the j subscript .

The matrix elements S11,S12,S21,S22 are referred to as the scattering parameters or the S-parameters. The parameters S11, S22 have the. To characterize high-frequency circuits, you can employ S-parameters (or scattering parameters) in place of the impedance or admittance parameters that. S-parameters are useful for creating and verifying high-frequency models over a large bandwidth. However, there are precautions to take into account.

If you want more information about S parameters, you can read "Microwave Engineering" by David M. Pozar. This book explain about S. This presentation covers the basics of S-parameters and their measurements for through the concepts of reflection, transmission and S-parameters with typical. Further to the explanation provided by Milo, I would like to simplify as the S11 parameter is primarily measured by a VNA and deals with the Power ratios as. An Introduction to S-parameters. 2.
