Bandwidth requirement of Ultra Wideband Antenna

[Vineeth m p]

Hi all,

The bandwidth allocated for ultra wide band radios is 3.1-10.6 GHz. My question is, is it necessary for an antenna in a device that operates within this band should be able to cover whole of this band?

hi there

well that would be up to the designer of the transmitter/receiver and its bandwidth requirements, then design a antenna to suit

there's no point in having an antenna that covers 7GHz if the equip only needs a couple of GHz

Hi there,
well, the antenna is considered to be UWB when it has minimum 25% of bandwidth within the range released by FCC

calculate it from here

BW = [f (higher) -f (lower)]/ f (centre)

f centre = [f (higher) +f (lower)]/2


hope this helps
