This paper presents about a new antenna design of ultra wide band antenna (UWB) for cognitive radio wireless communication. This antenna was simulated in ADS (Advanced Design System) Momentum. The feeding point is the micro strip line and to this attached the octagon loop structure. This antenna is operating in 32 GHz, 55 GHz and 70 GHz.It covers the ranges at band1 (25-45) GHz, band2 (50-60) GHz and band3 (60-80) GHz. For an antenna to be suitable for channel sensing it should possess an Omni directional radiation pattern. The octagonal loop antenna with rectangular patch is the sensing antenna which detects the spectrum and provides the available range for the antenna to communicate. The shape of antenna is highly designed to cover the wide band and provide spectrum reuse compatibility. The reuse of the spectrum is highly intelligent and highly efficiency.
