which s/w are you using?

This is depend on what S/W you use!

The Basic thing you need to do is define substrate

It is better to post in electromagnetic simulation forum.

if you dont have any software try to start with Ansoft designer (student version free)

hi,

this is very simple problem, for theory and analysis of the microstip you can refer to Microwave Engineering by David M. Pozar.

for Simulations you can use ADS/ Ansoft Designer (2D tool and 2.5D tool)
HFSS/Microwave CST/ Feko software/empire3D

Feko demo version is available, zirtapoz has already mentioned that Ansoft designer student version is free to downlowd.
