摘　　要：双极化印刷振子具有质量轻、体积小、成本低、便于排阵等优点,能发射或接收2个正交极化的电磁波,有利于频率复用或者收发同时工作。对双极化印刷振子进行了理论与实验研究,双极化辐射振子分别通过同轴结构进行馈电,顶部采用多层板结构实现馈线的交叉,这种多层结构改善了天线高频的辐射性能。与传统双极化印刷振子天线相比,该天线具有更对称的增益及更小的尺寸。The dual-polarized printed dipole has lots of advantages,for example,light weight,small size,low cost and easy to make array.It can transmit and receive microwave on two vertical polarized directions,which is conducive to frequency multiplexing or simultaneous operation of transmission and reception.A dual-polarized printed dipole is investigated theoretically and experimentally.Dual-polarized printed dipole is feed by coaxial feed,and multi-layer board lamination structure is used to realize the cross of feeder.It improves the radiation character of high frequency.Compared to the traditional dual-polarized printed dipole,this antenna has smaller size and more symmetrical gain.
