In this paper, the authors represent microstrip antenna for dual band applications such as Global Positioning System (GPS) and Bluetooth applications. The designed antenna must perform dual frequency operation i.e. 1.57GHz and 2.45GHz. So antenna resonates at frequency 1.57GHz for GPS and 2.45GHz for Bluetooth applications. Using CAD-FEKO electromagnetic simulation software, antenna has been optimized for continuous frequency band 1.2GHz-2.8GHz. This paper focuses on the designing of dual-band microstrip antenna with microstrip feed and co-axial probe feed and analyzes the results like return loss, VSWR, impedance, directivity and radiation pattern at 1.57GHz and 2.45GHz.
