Hi all,
im stimulating a 880-990MHz and 1.71 -2.17Ghz cellular PIFA pcb antenna with CST.
once done with the antenna structure, S11 and total eff. look good.
but im seeing abnormal high number(spike) at lower side for radiated efficiency. can anyone know what the root cause and how to fixed it.
thanks.

- CST Postprocessing of multiple S-parameters (single frequency parameter extraction)
- Shielding Simulation in CST
- Illegal usage of S-Matrix, No impedance found error in cst
- Line impedance in CST
- CST dual polarized H-slot antenna is very well matched but has poor total efficiency
- CST Matlab Interface, Export Far Field Result Automatically
