RWG functions to design patch antenna

hi everybody,

i want to use RWG functions related to the book "Antenna and EM Modeling with MATLAB" l ve downloaded the functions from the address "http://ece.wpi.edu/books/aemm/" when i run the programme some of them says it is only for student use , not for research.. Is there any body who knows where i can supply the full version of the programs and functions.

if anybody can help me , i would be glad..

Or is there any other functions to design and solve antenna problems.

thanks..
