In this article, a new antenna design for Radio-Frequency Identification (RFID) reader applications in the Ultra High Frequency (UHF) band has been proposed. The antenna is a perfect electrical conductor, excited by a 50 ohms microstrip line, set on an Epoxy FR-4 substrate. His overall size is (98*98*1.6) mm3. We achieve a UHF band antenna by cutting a circular slot on the ground plane and then adjusting the dimensions and position of a rectangle centered in the middle of ground plane. A good impedance bandwidth of 99 MHz has been achieved for UHF band. The antenna show high return loss of -66.12 dB in the center frequency of 0.893 GHz and the gain obtained into simulation of this antenna is 3.16 dB. The Voltage Standing Wave Ratio (VSWR) is less than 2 over the frequency range of 860-960 MHz. The structure design, optimization and simulation results analysis were performed under electromagnetic simulators CST and HFSS, and focused on the return loss, bandwidth, gain and VSWR
