I am desiging uhf patch antenna, I got little freedom
about the width of antenna ( less then 2cm), I cant
use more than that. I can change my lenth. Is there
anyway i can design this antenna with limited freedom
on width.
According to my knowledge if we
decrease the width input resistance of antenna increases.
can we use matching networks?, what type of networks
we can use.
resonant frequency is 915 MHz.
thanks

Hi , Dear vamsi,
you hadn't said anything
about the high of your substrate. if you have any
limitation on it?
three important parameters
that effect to the input impedace of microstrip
antennas, are the thickness of substrate , it's
relative permittivity and width of strip.
if you have limitation on one of them, you can
use two others to implement your design.
I hope , it'll be helpful
