antenna matlab

Hi, try this

http://www.ece.rutgers.edu/~orfanidi/ewa/ - ch17

or http://ece.wpi.edu/mom/index.html

I get nothing from your web ID~~~~~Is it just a book which about the subject?

Thanks,I will have a look.
Do you know where the antenna toolbox can be download?

The only Matlab toolbox i know about to simulate an antenna is Comsol Mulitphysics. It has an Rf-module where that can be done. Comsol was original Femlab, which was a toolbox for Matlab, which later got so big that it went off on its own. You can set up the simulation with Comsol then export it as an m-file.

http://www.mathworks.com/matlabcentral/ and search for "antenna" in upper right corner.

Yes Matlab is the best tool for simulating antenna arrays; Below i have typed some MATLAB code to simulate liner antenna array.
change the different variable and see the results.
