Radar Cross section Vs Reflection Coefficient

I am working on HFSS and designing Antennas for LOW RCS , in all previous works they calculate the S11 parameter for the unit cell then make an array form this unit cell and calculate the RCS , my question is what is the relation between S11 and RCS and why we calculate S11 for the unit cell only and if i modify the unit cell's S11 it will improve the RCS or not

Welcome to the PF. :smile:

Is this question for schoolwork or for regular work?

Thanks. I'll move it to the EE forum. Can you say more about the project? Why are you concerned about the radar cross-section of the antenna? What type of antenna is it, and what is the frequency range of the HFSS signal?
