Microstrip fix receiving wire finds a superior decision in remote correspondences in view of their less cost, light weight and simplicity of creation. Small size wide band reception apparatuses are of awesome request in future advances with the fast development of remote correspondence innovation. Notwithstanding innate impediment like thin transfer speed and low pick up, microstrip fix receiving wires have various preferences. Be that as it may, different strategies have been examined for the improvement of both transfer speed and gain. This paper proposes a novel outline with deserted ground structure so as to get better data transfer capacity. The structure is designed at 8.5 GHz using FR4-epoxy as substrate material that has relative permittivity 4.4 and loss tangent 0.02. HFSS (High Frequency Structure Simulator) software is used for simulating the proposed design. This antenna obtained the return loss -12.87 dB, -14.36 dB at 5.5 GHz and 10.5 GHz with a VSWR of less than 2. In order to enhance the bandwidth of the antenna, defected partial ground has been used which truncate at the edges so, that bandwidth of more than 1 GHz has been achieved at both resonating frequencies. Gain of 4.24 dB and 6.27 dB has been obtained at 5.5 GHz and 10.5 GHz. The efficiency of antenna is also found to be good and proposed design has suitable characteristics so that it can be used in WiMax and Radar applications.
