how to design microstrip for 1.645GHz freuency

[kan1]

i designed microstrip antenna for 1.645GHz frequency.i got length=0.0423m,width=0.0545m, i m using inset feed method for matching in which i m getting the following values k0=34.45,G1=9.93*10^-4,G12=5.756*10^-4,Rin=322.45...i m getting the inset length to be 0.899m.which cannot be used with a 0.0423m length patch.so plz suggest me a matching techique with 50ohms impedance...anyway i dont want to go 4 quarter wave transformer method since i ll be studying the harmonic response of the patch later n also i want to simulate in hfss.....

I know where you made your mistake.

While calculating the value of the inset (y_0), you have to inverse the cosine. Important thing is that, all the calculation would be in RADIAN not in DEGREE. Your inset value would be 15.7 mm.

oke
the step are
1. chooose the frequency that you want to make
2. determine the power line
3. simulated in software.
