design of antenna using hfss software

hello..
i am doing my final year project
title is design and simulation of tri-band antenna for mobile applications
can any one help me from basics
can any one send material for designing of a basic antenna using hfss software
first i want understand the software & tell me have calculate antenna parameters

Hi,
There are hfss examples for antenna. The simplest way, i believe is to use hfss antenna design kit to create the model. After that, you can optimize the antenna for your application

provide me a link
to know some examples and design steps of an antenna

can you send me some design examples of microstrip antenna

there are several antenna examples that come with HFSS. click file->open examples->antennas.
microwaves101.com is a good starting resource.
