UltraWide Bandwidth (UWB) antenna with Deflected Ground Structure for wireless communication is presented in this paper. Our proposed antenna design is consisting of elliptical shape slot at patch and Quarter wave transmission line at the ground with multiband frequency operation in various wireless communications.An antenna is designed using FR4 substrate with permittivity value of 4.4 and thickness of 0.8 mm. The size of the antenna is 50 x 70 mm2presents a high gain of 4 dB with Ultra Wide Bandwidth. In proposed antenna quarter wave ground is imposed with Deflected Ground Structure to achieve overall size reduction. The ultra bandwidth antenna proposed in this paper operates at multiband frequencies centered at 3.0267 GHz, 6.1933 GHz, 9.1911 GHz, 12.1467 GHz, and 15.06 GHz with corresponding return loss of -24.0553 dB, -40.9292 dB, -20.7534 dB, -41.8718 dB, -30.1747 dB.
