Microstrip antenna is the typical narrow frequency bandwidth antenna, especial for the higher dielectric. In this paper, from the input impedance of the rectangular microstrip antenna, the dual-mode of the microstrip antenna is used. By the using of the mode and , the relatively bandwidth could reach to 2.7% from 0.7%, which calculated under the higher relatively dielectric constant. The simulation result is given at the same time.
