I need simulate an antenna in HFSS for RFID. The internal impedance of IC at 915MHz is 12.8-j248 (NXP UCODE7). This is a serie impedance.
To simulate this impedance I use a Lumped port with equivalent parallel resistance Rp ~ 4.837K and a capacitance of 0.7pF in parallel using a lumped RLC. Both in parallel connected to a dipole input.
Antenna needs be 12.8+j248 impedance for perfect match.
My question:
When I measure Z11 in HFSS, the real and imaginary part showed is parallel or serie modeled?
My doubt is because real part depends of the configuration.
