[steve weir <weirsi@xxxxxxxxxx>]

praveen, I think it sounds confusing to you because you are probably 
thinking transmission line where the idea is to convey the energy from 
one end to the other, instead of antenna where the idea is to launch the 
energy into space.  You should get a hold of a book on antenna design.  
You should also be asking questions about that spec.  You need to know 
things like:  the frequency the antenna will be working at, the 
radiation pattern, the gain requirements, etc, etc.  Once you have a 
viable spec for what the antenna needs to do you can try and map it to 
any of the well known antenna designs and your packaging restrictions.

If you don't have field solver software or a canned design to work from, 
I seriously recommend you farm the antenna design out to an RF house 
with the tools and experience to do this job properly.
