hello

I'm looking to design a microstip array antenna using HFSS in 77GHz. Any help in how to start and in how to implement this design. I'm newbie to antenna design :o

Thanks,

All the theory you need to do the project is on this page:
http://www.antenna-theory.com/antennas/patches/patch.php

Write out the half-wavelength at 77GHz, then figure out the size the patch needs to be. Determine the requirements for your array (gain, scan angle, whatever), and write down the solution on paper.

Then model it up in HFSS, and optimize the parameters as need be.
