In this paper a new design of microstrip antenna is presented. A rectangular microstrip patch antenna designed with strip line feed. Rectangular slots employed on patch for resonating in two frequencies at 2.4GHz and 3.5 GHz. To improve the working efficiency of proposed antenna, a Defected Ground Structure is used. FR4 epoxy material is used as substrate of height 1.6 mm with relative permittivity of 4.4. The proposed antenna has the dimensions of 50 x50 x 1.6mm3. The proposed antenna is designed at two resonance frequencies of 2.4GHz and 3.5 GHz for Bluetooth devices, Wi-Fi, public wireless hot spots and WiMax.
