In this paper, the authors propose a new structure patch antenna excited by two identical microstrip lines having a common feeding adapted to 50 ohm and intended to applications of Radio Frequency IDentification (RFID). The slots inserted at the patch antenna have a direct impact on improving the radiation characteristics in terms of reflection coefficient, voltage standing wave ratio, input impedance and directivity over a range of frequencies ranging from 2GHz up to 2.9GHz. The analysis and optimization have been performed using the simulator HFSS (High Frequency Structure Simulator) based on the finite element method.
