Synopsis :
This paper presents about a new
antenna design of ultra wide band antenna for cognitive radio wireless
communication. This antenna consists of polygon on a printed circuit board;
ground plane. This antenna was simulated in ADS (Advanced Design System)
Momentum. The feeding point is the micro strip line and to this attached the polygon
structure. A ultra wideband antenna is necessary in order to achieve the
channel sensing which should possess an Omni directional radiation pattern. The
ultra wide band antenna covers a spectrum from 5GHz to 12GHz for channel
sensing. The resonant frequencies of the antenna are 7GHz and 9.77GHz.
