    Hello Dear Anurag
    I have designed a spiral coil on the PCB. Now I have a question about how we can simulate B/I (B field over current) and optimize it? Thank you very much for your help

      Hi Peyman,
      There is no direct way of plotting and optimizing B/I that I know of....I would recommend you to contact your local Keysight tech support team on this and they will let you know there is any way to accomplish that.

    Nice content Sir.
    Can we change the the ports amplitude and phase at this point in Layouts especially in Far Field Visualization,or one should have to export the design to schematics.

    • @BhargavaAnurag

      Hi Nabeel, You could that in the visualization window itself. If you want to make a multi-port injection that's also possible as well and you can set amplitude and phase for each port. This will be very useful for phased array kind of simulation. In ADS, you can drive the entire far-field etc with the known amplitude & phase from schematic itself and steer the beam as required. I will try to create video for that at a later time...

    Thank you Anurag! Can we compare the far field emissions to CISPR standards as well like we do in EMPro. Also I want to find the emissions from my board with different sets of decoupling capacitors. Since the capacitors will change my PDN I expect to see different emission levels too. How can we do that in ADS? Thanks!

      Hi Asif,
      Currently PIPro doesn't support the emission analysis directly like you can do in EMPro or for Power Electronics using PEPro inside ADS (which is having quite similar UI as PIPro but targeted towards VRM/DC-DC converter designers).
      However, one of my colleague has created a schematic template allowing you to compute the far-field emissions easily once you bring the PIPro board alongwith Capacitors into ADS schematic which should serve your purpose. You can write mail to eesof-europe_support@keysight.com and ask for EMI emission schematic test bench example and they should be able to help you....👍

    Thank you for nice tutorial.
    I have two queries.
    1. can I investigate the effect of a switching diode (diode or equivalent circuit of diode) in antenna such as reconfigurable antenna by using the antenna symbol/model in schematic?
    2. If the answer of the 1st question is yes, then can I check far field pattern and axial ration from this symbol of the antenna with diode? (as you showed how to check fir-field in case of parametric analysis. Thats why I am little bit confused.)
    TIA.

    • @BhargavaAnurag
      @BhargavaAnurag  4 роки тому +1

      Yes, you can. Kindly wait till I reach Phased Array Antenna topic, there we will discuss entire TR Module system driving the antenna and we can look at Beam Steering etc etc...it will be much more than what you asked...😊

    After reading the comments, I think I've to watch the the Phased Arrays videos playlist as well.
    I'm curious about exporting the far field data like dialogue box showing gain and Directivity etc.
    Is it possible to export the desired data in a CSV or other format to do post processing in MATLAB e.g. in mimo, I may need to calculate correlation coefficients.

    • @BhargavaAnurag
      @BhargavaAnurag  4 роки тому +1

      You could do MIMO correlation coeff within RFPro environment inside ADS when you simulate your antenna. See this video and try it out on your ADS side and look under Diversity Tab: ua-cam.com/video/7lsdM34y9_E/v-deo.html (I haven't explained Diversity tab in this video but once you know how to use RFPro then you can explore it on your own)
      There is a way to export Far Field data from ADS, detail of which I can provide you if RFPro itself can't do everything you want to do but I will let you try RFPro first and we go from there...

      @@BhargavaAnurag thank you for the clarification. I'm planning to watch all playlists/videos to learn SystemVue, RFPro, Genesys (if it's tutorials are planned in future), and phased array etc. So hopefully I am sure I'll learn many things.

    Dear Anurag, many thanks for this short tutorial. At 0 GHz you clearly show no radiation is produced. That's ok, but in the current plot at 0GHz we find 21.8 A/m peak value of current density (i.e. 5m06sec). In the schematic there is no DC bias applied. I would have expected to find no current density a 0 GHz. How do you interpret this non-negligible current density? I am learning quite a lot of tricks for ADS in your tutorials. great job!

    • @BhargavaAnurag
      @BhargavaAnurag  2 роки тому

      Hi,
      Its a low pass filter layout so DC will pass thru hence the current density. You don't need DC bias for that as the S-Parameter is simulated from 0-xxGHz, the EM simulator obviously doesn't simulate DC but very level KHz signal and that's extrapolated to DC hence the current density.
      Hope this helps.
