%X this paper presents the design of notched-band antenna with cpw - feed. the notched - band has been achieved by using the w-shape slot in ground plane. the antenna has been simulated using a 3d - electromagnetic simulator. the experimental results of proposed antenna exhibit ultra wideband characteristics from 2.0 - 15.0 ghz except the notched-band frequency from 5.0 - 6.0 ghz. the slot is optimized with respect to width, length and position for a detailed study of notched-band characteristics. it is observed that the centre frequency and bandwidth of notched-band depend on the length and width of slot respectively. the experimental radiation patterns of this antenna are omni-directional in h-plane and bidirectional in e-plane. this antenna can be useful for uwb system, medical imaging and vehicular radar.
