any 1 help to adjst gain of abov antennas plss

i am unable to open your hfss file

yeah cant open your file...

The problem i see is with the gain, from your file. redefine the radiation boundary. unfortunately your radiation boundary is not defined properly. your way of defining radiation boundary in all the files you have uploaded so far has been the same.
