| Abstract: | A dual-band circularly polarized microstrip antenna based on cavity model theory,multiple feed points and loading shorting pin technology was designed.The property of the microstrip antenna was simulated using the finite difference time Domain(FDTD) method.The results show that this antenna can obtain dual-band circular polarization,and has excellent features such as small size,wide band and so on.It has important prospect in the development of wireless communication. |
