Hello guys
i have a problem with measuring the Bandwidth of a dual band PIFA antenna.
lets look at the following S Parameter figure ,, we see that the lowest magnitude is -7.9dB
so How do i measure it ,, do i subtract -3dB from the loweset value and take -4.3dB as upper and lower cut off frequencies like showing in the following figure
i hope u can answer my question and sorry for being long
