Could someone kindly tell me the techniques to improve S21?
My antenna uses 2 ports: port1 uses CPW on the top of substrate, port 2 use microstrip line on the bottom of substrate
S21 is <-8 dB now, i hope it will <-15 dB and keep the same antenna's operation.
Thanks!
i found one antenna in IEEE that has adding ground which is perpendicular connected to CWP fed line
Could someone show me one antenna that using the same ideal but the feed line is microstrip fed line.
What is the name of keyword for searching this ideal, i don't know how to call this adding...
Hi Shehata,
thank you for your considering. There is one thing in your answer that i couldn't understand, please explain it for me!
You could look at the picture that i attached
i set up the calculation is: "max(dB(RealizedGainTotal))-min(dB(RealizedGainTotal))", the plane here is zy so...
How to set up the Goal in optimization setup in HFSS in this case: the antenna is on xy plane, i want to find the value of a variable so that the antenna is Omnidirectional in yz plane
I don't know how to set up the goal, the condition.. in optimization setup menu
Thank you very much!
thank you for your reply .
I am sorry about my big negligence.
Actually " I want to design an simple antenna at 16 GHz on PCB (x-y plane). I want it to be directional in the 0y", not in the 0z :(
At the beginning, i use tapered slot antenna but it is not simple enough.
I hope you could...
Re: someone helps me! i need " electromagnetic scattering by surfaces of arbitrary sh
oh yes,i need it so much.thank U very much.in my country,it is difficult to search material for studing:(.
someone helps me! i need " electromagnetic scattering by surfaces of arbitrary shape"
if the friend has the ebook"electromagnetic scattering by surfaces of arbitrary shape",can you share it for me.Thanks U!
