摘要：This paper presents a Wide Bandwidth Microstrip Yagi antenna with very good performance at two operating frequencies (1.128GHz and 1.986GHz).This microstrip antenna works on two band of frequencies .The first band lies between 1.06 GHz to 1.196 GHz and it resonates at 1.128 GHz frequency then its calculated bandwidth is 12.05% and the second band is lies between 1.621GHz to 2.351GHz and it resonates at 1.986 GHz frequency then its calculated bandwidth is 36.75%.Numerical simulation results of our design show more than (-10 to -25) dB return loss at the bands of (1.128 and 1.986) GHz and VSWR less than 2 at these frequencies.The simulation method based on finite ground plane method is applied by using IE3D simulator to obtain the optimized parameters in order to find the best design for this antenna. Simulated result of the proposed antenna is shown in figure below and use in GPS and mobil communication
