This paper presents the design and development of simple low cost rectangular microstrip antenna for multiband operation. By incorporating U-slot of optimum geometry and open stubs at two opposite corners on the rectangular radiating patch the antenna operates between 1.815 to 9.01 GHz at different frequency bands with a virtual size reduction of 44.84% and gives broadside radiation characteristics at each operating band. By placing U-slot and open stubs at the corners, the copper area of the patch is reduced to 8.50%, when compared to the copper area of conventional rectangular microstrip antenna designed for the same frequency. The experimental and simulated results are in good agreement with each other. The design concept of antenna IS given and experimental results are discussed. The proposed antenna may find applications in mobile, WLAN, WiMax and SAR.
