hi to all
i have tried many PIFA structures in that ,i can able to achieve good return loss (near 1 db),good bandwidth (around 730Mhz),even efficiency around 85 to 90%,but iam not able to get good radiation pattern(that is iam getting back lobes).for the mobile applications the required radition pattern is near omnidirectional in azumithal plane. but iam not geting that.herewith iam enclosing my geo.file.kindly see the radiation pattern of this enclosed geo file and suggest me that how to rectify my radition pattern problem.i know that the finite ground plane affect the radiation pattern .but what is the remidy for that.suggest me sir please!
thanking you
