WebMay 22, 2024 · Scattering parameters can be derived analytically for various circuit configurations and in this section the procedure is illustrated for the shunt element of Figure 2.3.5. The procedure to find S11 is to match Port 2 so that V + 2 = 0, then S11 is the reflection coefficient at Port 1: S11 = Y0 − Yin Y0 + Yin. WebIn our research we must add complex impedance to antenna. I use CST and my friend use HFSS. I've read about it and add as shown in a picture then calculate S11 for various frequencies. You can see ... WebA capacitor or inductor have imaginary impedance (no real part, just an imaginary part. The imaginary part is called "Reactance", and L and C are called "reactive elements". Reactance is the ratio of V/I, so it has the units of Ohms, just like resistance. The impedance of an inductor is Z = jwL. how big is an iphone 14 pro max
