Design Of Microstrip Antenna..

i am designing microstrip antenna for bluetooth........can any one provide me some help...freg is 2.4ghz,substrate duroid having dielectric constant 2.32 and thickness of substrate is 0.127

you can use from software zeland(ie3d) for simulink microstrip antenna.
that software is very good in microstrip antenna. this software is method fullwave in electromagnetic.
you can refer to www.zeland.com for download zeland v12

try Microwave office from AWR

Try CST. HFSS costs alot of time, and the result is the same as CST
Other while CST is very easy to use

Added after 4 minutes:

With this low Frequwency , why do not you use the FR4. It is very cheap compare to Duroid.

Further more you can use the other company's subtrate like Neltec SA France . You can get the same material with duroid but the price is only a hafl.

IE3D,HFSS or anyother standard software u can use. but in paralle keep some standard ref books for microstrip antenna design.
one good book is by bahl and bhartia--- for microstrip antenna design

There is a very similar example in Ansoft - hfss_V10_book

try MIcrowave office, good for microstrip simulation but need high memory capacity
