Hi everyone,
I'm trying to design a microstrip patch antenna but when i simulate on Ansoft Designer i don't find good results.
First, i find W with W=(c/2fr)*sqrt(2/\[\epsilon\]r+1)
then i find L with L=c/(2fr*sqrt(\[\epsilon\]eff)) - 2\[\Delta\]L
and then i don't find the input impedance. When i search into internet i find different calculs:
1) Zin= (90*\[\epsilon\]r^2*(L/W)^2/(\[\epsilon\]r-1)
2) Zin = \[\frac{1 }{ Yin}\] with Yin= 2G with G=\[\frac{W }{120\lambda\]o*(1-\[\frac{{(ko*h)}^{2 }}{24\])
What's the good answer ?
I have a second question: is it possible to create microstrip line antenna ? It's mean not a rectangular antenna but line antenna ?
Thanks a lot!
PS: Sorry for the equations...
