That was not the equation stated.
Unfortunately I don't understand what did you mean.
If you're talking about this equation from "Microstrip Antennas" book:
BW = (VSWR - 1) / (Q * sqrt(VSWR))
it uses fractional bandwidth, which can be calculated as:
BW = df / Fc = [delta frequency bandwidth] / [center frequency]
This is why I used this equation:
Q = 1 / BW
This equation uses BW symbol to represent fractional bandwidth. Sorry, english is not my native language, so I used word "relative bandwidth" and it may be confused you.
