The proposed antenna presents the design and analysis of triple rectangular ring antenna with Defected Ground Structure (DGS). The antenna used DGS to reduce the size of antenna. In this paper, antenna enhances its performance in the area of WiMAX, WLAN and IMT band. The range of band (2.55-3.82GHz), (4.84-6.0GHz) and (7.01-7.30GHz). This design represents multi band frequency with wide band width and better return loss due to DGS effect. In this design patch is made in the shape of rectangular ring and using FR-4 substrates with dielectric constant of 4.4 and tangent loss 0.0009 respectively.
