Microstrip patch antennas are by and large broadly utilized in the majority of the wireless communication systems because of its lightweight, minimal effort and simplicity of establishment, so they assume an overwhelming job in the advanced communication systems. In this paper, we propose a reduced patch antenna for ultra-wide band applications. The proposed patch antenna design resonates between 2.26 GHz to 9.55 GHz. To accomplish ultra-wide band a defected ground is used in the proposed design. Throughout the resonating wide band, the minimum reflected power obtained is -49 dB at 5.8 GHz which is a ISM band and the VSWR is below 2. The obtained gain is greater than 3dB thought out the band and the highest gain is obtained at 9.5 GHz i.e., 5.7 dB. Also, the proposed design has good radiation characteristics both at azimuthal plane and elevation plane. HFSS software is used for simulating the design.
