A broadband high gain microstrip patch antenna using slot is proposed. The Antenna has low profile with enhanced bandwidth and gain. The slot use on the patch's surface affects the radiation characteristics of proposed antenna. The antenna operating frequency range is 4.4 - 6.4 GHz with VSWR less than 2. By using slot on rectangular patch with coaxial probe feed a wide bandwidth is achieved. The IE3D simulation result shows that the proposed antenna has 37% impedance bandwidth. The return loss of -38.82 dB, Gain of 3.8 dBi, Efficiency of about 80% and VSWR of 1.023 is achieved at 5.36 GHz.
