Hi
I designed 1:2 unequal wilkinson power divider for array antenna with Er=2.2 h=.254mm in ADS
The impedences for power divider are z0=30ohm z1=Z0*sqrt(k*(1+k^2))=34.15(90deg) z2=z0*sqrt((1+k^2)/k^3)=54.12(90deg) z3=z0*K=26.74 z4=z0/k=33.66 and R=61.6ohm..
The distance between the elements is 0.8lamda 6.857mm..I connected thedesign as
30ohm-26.74ohm-34.15ohm-61.6ohm-54.12ohm-33.66ohm-30ohm.. I adjusted the length of z3,z4 and R to obtain the desired length and frequency ..
the s31 and s21 parameter is invalid .. can anybody tell me whether my approach is correct ?
