Hi all,

which antenna is better in term of efficiency and bandwidth.
PCB or FPC?

and which one is more immunity to detuned by proximity object(human hand/body/plastic case/metal)
 

You have not mentioned what PCB material you refer to.

If we assume a PCB with moderate permittivity and some loss, my estimate is:
  • FPC antenna has more field in air (outside substrate), so it has less dielectric loss => better radiation efficiency
  • PCB antenna has more field percentage in PCB substrate and is thus less sensitive to detuning by nearby materials.
  • Bandwidth is difficult to estimate, because it depends on losses (more loss => more bandwidth) and it depends what we compare (FPC antenna same physical size as PCB antenna? or both full size for the respective permittivity?)
