摘要：

A dual-frequency dual-circularly-polarized vivaldi antenna array is proposed in this paper. The array element is constructed by crossing two vivaldi antenna. To realize function of the circular polarization, the array element is fed by a 3dB bridge. The best structure parameters are fond by using Genetic Algorithm (GA). Simulation results of impedance and axial ratio show that array can work in dual-frequency band. Based on these properties, the proposed antenna array has great benefit to the design and performance analysis of dual-frequency circularly-polarized phased array antenna.
