HELP!! Characterization of Low Frequency RFID Tag

i'm doing final year project on title i mentioned above.
i have few questions need to ask:

1)may i know how to conduct an experiment for a LF RFID tag by simulation?
2)how to ensure the characteristic of a LF RFID tag?
3)what is the mean of performance for a LF RFID tag?
4)any example for radiation pattern on LF RFID system?

actually my project required to do the simulation by MATLAB.
but if anyone here got any idea on conduct the experiment by other software, please tell me the step or idea, i will try to make it in MATLAB.

PLEASE HELP ME! I SUBMIT DRAFT TODAY BUT MY SUPERVISOR SAID MY PROJECT NOT MEET REQUIREMENT AND ASK ME TO REDO IT AGAIN. IF I CANT MAKE IT IN THIS FEW DAYS, I WILL NEED TO EXTEND. SO, PLEASE HELP IF CAN.

thanks..

beside that.. may i know how to create a patch antenna parameter by matlab? after create the antenna then just i can do simulation on it.. how to characterize the patch antenna in low frequency RF term?

Please help me if can...i really need help now..
thanks...
