Microstrip patch antenna

[Aniruddha Xab]

Need help to design microstrip patch antenna with
Resonant frequency = 2.4 GHz
Dielectric constant = 4.4
Height of dielectric substrate = 1.6 mm
in ansoft designer student version 2.2

hi!!!
u should refer a book Antenna Theory And Design by Balanis to calculate the dimensions of rectangular patch, the layout of which u can easily draw in HFSS or ADS..

Thanks for the suggestion of book, i have gone through it and calculated the width of patch as 38.036mm
and Length as 29.443mm with input impedance (edge) around 243 ohm
but whenever i tried to simulate it, it says structure is to large for simulation with student version. What should i do now.

upgrade your software

You can use the free Sonnet Lite EM simulator:

Thanks Dave
But how to upgrade the software, there is no update option in software.
and i have not found any other free version.

using hfss how can i plot gain curves E-Field and H-Filed plots??
