In the present day scenario the need for wireless communication is increasing in order to support more users and to provide more information with higher data rate. Ultra wideband is a wireless technology used for high speed data transfer over short distances. But in the ultra wideband frequency band there are some other frequency bands like WLAN, WiMAX, C band, X band etc. which may cause interference with the ultra wideband . Therefore notching technique is used in order to remove the interfering band from the ultra wideband range. In the proposed work a dual band-notched antenna with DGS for ultra wideband applications is designed and fabricated. Size of the proposed antenna is 36 x 33 x 1.6 mm3 and FR-4 is used as the substrate for the proposed antenna. Antenna is resonating in the frequency range of 2.5-12.5 GHz with peak gain of 5.47 dBi giving total bandwidth of 10 GHz. Antenna is having two band notches from 3-4 GHz and 6.95-7.8 GHz removing the WiMAX and XSCS band from the ultra wideband range. Simulation of the antenna is done in HFSS and fabrication of the antenna is done using PCB designing machine. Testing of the antenna is done using vector network analyser (VNA).
