When exploring s11 parameter, it's essential to consider various aspects and implications. What's the S parameter in an Antenna. So, I'm struggling to understand what the S-parameter is in real-life terms; I mean, what does the S-parameter tell us about an antenna? I have designed a microstrip Wi-Fi antenna that should work at How to find Z impedance if I have only S11 (db) and phase.
I do not know line impedance. The output of VNA is 50 ohm. S11 is the return loss, it shows the difference between the level of the output signal to reflected signal and it is shown in negative values -db.
How to interpret S parameters on a Smith chart. I am unsure as to how can I spot the S11 values from the Smith chart that the datasheet provides. For example, for the S11 I have the below figure from the datasheet. S11 is on the input side, where I have a 50 Ω source, so the input (source) is on point A. My question is: How do I find the S11 parameter from this graph?
Similarly, frequency domain S11 conversion to time domain TDR. Below we see the S11 plot of a transmission line, the Wikipedia definition of the reflection coefficient as a function of S-params. As I see it, the S-param frequency domain plot comes from the time
Similarly, how to measure S11 of antenna using VNA for one port S-parameter .... Set a suitable frequency range for the antenna, connect the antenna to the Port 1 of the VNA and measure the S11. If the antenna is working, you should see the resonance dip on the graph: The lowest point of the dip tells the frequency in which the antenna radiates most of the power (least power returns to VNA port).
[SOLVED] - Positive S11 Parameter - Sample HFSS file uploaded. I've heard that getting positive S11 parameters is a simulation issue. It's important to note that, can someone please help me know what settings to tweak in this file so i can get the correct S11 parameters? Please, If you can solve it, specify what you did.
By the way, in this simulation, I'm trying to use glass... S parameter meaning - Electrical Engineering Stack Exchange. Moreover, s11 is the return loss. -25 dB is very good for a return loss parameter, almost too good to be true. This means that only 0.3% of the input power is reflected back to the source, and implies an almost perfect impedance match at the input to your patch.
impedance - Interpretation of scattering parameter - Electrical .... Currently I am (non-engineer) trying to understand the origin of measured scattering parameters with a vector network analyzer and a 2 port system. The second port is terminated with a matched load...
