Hi
thank you
my balun's impedance is 50 to 200 ohm ,and it have return loss better than 10dB in 200 ohm (my structure is Microstrip to CPS)
input impedance of antenna is 200 ohm and it work really good in 2-10GHz (my antenna is sinuous antenna with 2 arms
it is very amazing that when I connect them toghether ,results are so bad
may there are another problem ? because I dont have mismatch
how I can use of Z smith chart , do you know ?
both work very well in same impedance but when they connect, all things are owful
I think may I use of z smith chart , is it good ?
