摘要

提出了一种具有宽带性能的新型双极化磁电偶极子天线。辐射贴片的折叠锯齿边缘有助于更好的阻抗匹配，以及紧凑的尺寸。该天线采用交叉耦合馈电结构，实现了双极化和高端口隔离。为了提供实用的设计指南，进行了参数化研究。仿真结果表明，在VSWR≤2.0的情况下，在1GHz ~ 3GHz范围内实现了100%的阻抗带宽。在整个操作波段也获得了低交叉极化水平的稳定辐射图。

Design of a Wideband Dual-Polarized Magneto-Electric Dipole Antenna

A novel dual-polarized magneto-electric dipole antenna with wideband performance is presented in this communication. The folded jagged edges of the radiating patch contribute to a better impedance matching, as well as a compact size. The antenna is fed by a crossed coupling structure, thus dual-polarizations and a high port isolation are obtained. A parametric study is performed for providing practical design guidelines. Simulation results show that an impedance bandwidth of 100% for VSWR ≤ 2.0 from 1GHz to 3GHz is achieved. Stable radiation patterns with low crosspolarization levels are also obtained across the operation band.
