A compact wide-bandwidth and dual-polarized antenna is presented in order to detect different radars effectively. The antenna can achieve VSWR≤2.5 and good radiation pattern which can meet the covering airspace requirements of the phased array. By analyzing the antenna array theory, the array polarization switching and beamforming are realized simultaneously. The measured results of the array reveal that it achieves multi-polarization at bandwidth of f0 to3f0, scanning angle of ±45° in the azimuth and ±20° in the elevation. The design has laid a technical foundation for the naval vessel RF integration system.
