摘要：
A low-profile dual-polarized ultrawideband phased array antenna with a wide-angle impedance matching (WAIM) layer is presented in this paper. This antenna is comprised of the printed tightly coupled dipoles elements without external matching network. The innovative introduction of resistive sheet in multilayer PCBs is helpful in reducing the profile, which is achieved as small as only 3.7mm (0.22 lambda(H)). The proposed dualpolarized infinite array achieves 6 similar to 18GHz(3:1) when scanning up to +/- 60 degrees in E/H plane. A dual-polarized 12x12 prototype is fabricated and measured, verifying the validity of the design.
