hiya, i'm a 2nd yr Beng student currently studying
patch antennas. i really want to know the effects
of changing ground plane size,director size and
height, feed line width and patch diameter, etc
in dual stub circular patch antennas, similar to
those in some 3G base station antennas.
i already know changing of feed line width and ground
plate can alter the bandwith, but why?and i can
hardly find some explanation of how director works,
and why it helps to increase the operation bandwidth.
it seens every diameter being changed is related
to bandwidth, why?
( i really want to know
the effects of changing ground plane size,director
size and height, feed line width and patch diameter,
etc )
thanks a lot for helping me!!!!
