Dear Asad
I tried Running your file Last Night. one thing i saw was, your conducting layer was not assigned. so the reflection coefficient was completely messed up. and unfortunately when i started running the file,laptop crashed. i will try running it one more time and give you any feedback possible.

Dear Asad
I Ran your simulation, and VSWR looks perfectly fine to me, since you are trying to get a UWB printed monopole. the radiation pattern has to be near omnidirectional.which is quite the pattern you are getting i supposed, the only problem i saw in the design was you forgot to assign a material to your conductive layer.another thing that was with your design was that the simulation was not converging at all. after you increase the number of passes and fine the size of the mesh, results are very coherent.
Let me know if you need any further help

as soon as possible
i thnk after removing slot gain and patrn can be little bit imprvdAsad
i have tried running the simulation, you patterns are not exactly omnidirectional . gain is very poor as well

hi sir sajid, i have designed rec. and hex. uwb antns ,results are fine but gain is poor ,sir pls chk them and adjst gain of both antnns,should have cnstant gain over entire range.pls reply as soon as posibl
