What type of antenna are you asking about on band width.

I built a vertical and had my then 14 year old son assisting me.

I thought I had it tuned great when my son told me it does not matter what frequency he puts the mfj analyzer on it always reads around 1.1:1 VSWR.

I thought to my self wow the perfect antenna resonant every where. Then I thought I might need to go see how my son was actually using the analyzer.

Found out that my son had connected the antenna switch to analyzer and had the switch set to the dummy load position.

The dummy load has GREAT band width but the efficiency is rather poor.

The higher the Q of the antenna usually means less bandwidth.

Keep in mind most antennas only have the maximum gain at design frequency and loose gain as the frequency of the transmitter is moved away from design frequency.

So back again to exactly what type of antenna are you asking about?
