hi freinds
i need program with matlab for antenna simulation that in first of program get "L" and give "E" and "H" and drawing "E" and "H" and get "f" and give antenna pattern 1D and 3D and get maximum input current (phase and amplitude) and give "radiated resistance" and directivity and drawing current of antenna . and if move feeder from middle of antenna to desire point all above parameters calculate again.
please guide me
thank you for your help
