Thanks for Volker's tip, I will contact them in the meanwhile.
Hi vfone,
My HFSS setting is as follpwing,
Solution type: Driven Terminal
Substrate: 0.55mm FR-4, 4.4 permitivity with 0.02 loss tangent
Trace: 1.4mil copper, 5.8e7 siemens/m
No bottom ground.
Excitation (input): resistance=21, reactance=199j
Plot reference as following,
I just wondering, does test result should be matched between antenna resonant frequency and antenna measurement result?
Or, practically, antenna resonant frequency by simulation is just a reference?
Thanks,
