A novel design of a dual band antenna, consisting of U-L shaped structure with wide slot in the ground plane is presented. To improve the bandwidth, capacitive coupling and stubs are introduced in the radiating element. Further to improve the bandwidth, a wide slot in the ground plane is employed. The proposed antenna is printed on 1.6 mm thick FR4 substrate which has a relative permittivity of 4.4 and a loss tangent of 0.008. The radiating element size is 20 X 18 mm. The measured impedance bandwidth for the first band is 3.7 4.2 GHz (12.66%) and second band is 5.3 6.9 GHz (26.23%) at 5.6 GHz. The peak gain is around 4 dBi at 5.6 GHz.
