hello all,
i do design for antenna RFID uhf in ZELAND and i integrated with virtual chip , my first was good but i can design a good antenna in HFSS .. if any one can help me that will begreat for me >
and for the chip i have question about the modulation of the receptor of the Radio Frequency .
my question is : if we can make chip have 2 modulator HF and UHF , because i have design for antenna dual-frequency

Hello
I have a question regarding the calculating S11. You used this formula. S11=(Zant-*Zc)/(Zant+Zc). the denominator only Zc. Is should be Zc or *Zc. Please I would like to understand this formula
