  • how to calculate size,length,taper rate in vivaldi design for 3. 3GHz . . .
    how to calculate size,length,taper rate in vivaldi design for 3 3GHz as center frequency? can i take frequency range from 3 1-3 5ghz? length of taper = lambda lambda is centre frequency or upper or lower freq? width of taper = lambda 2 lambda is centre frequency or upper or lower freq? where to put probe can i put full plane port?
  • How to optimize S-Parameter? | Forum for Electronics
    But I can not able to do this I tried to use all the parameters but could not I used Pattern Search Optimization, Quasi-Newton Optimization, and parametric of available variables the third picture is of my antenna it is a Vivaldi antenna so anyone have an idea or suggestion, on how can I improve my s11 by more than -20dB!!!
  • How can I explain the Vivaldi antenna operation?
    Can anyone help me to understand how this Vivaldi antenna works? 1 For the feed line, I can see a microstrip line that ends with an open-circuited radial stub! But how does it help to match the impedance? 2 In the top plate, why the cavity added there, how the total operation is actually
  • radial stub radius of circle design in vivaldi doubt
    i'm designing vivaldi antenna with centre frequency 3 3 Ghz (2GHz -4GHz) using CST Taper length of antenna is 90 9mm for 3 3 GHz Aperture width 48mm(ie; > 45 5mm) Its having microstrip to slotline transition from 50 ohm to 100 ohm I am getting efficiency >100%(because gain is more
  • [HFSS] - Vivaldi Antenna with SMA transition | Forum for Electronics
    Hi everyone, I just designed and manufactured a Vivaldi antenna with the intention of operating from 8-18 GHz In simulation (HFSS), with a Lumped port, my return loss is very good (<-20 dB) I also modeled the end-launch SMA connector according to the manufacturer's specs and get a decent return loss in simulation (<-10dB)
