【摘要】 本文提出了一种应用于5 G毫米波的双极化磁电偶极子天线。该天线主要由四个短路贴片和微带馈电网络构成,采用金属化通孔对贴片直接馈电的方式,将双极化的馈电网络设计在同一金属层,并采用差分的馈电结构提高了端口隔离度。仿真结果表明,该磁电偶极子天线在23.3-29.6 GHz(相对带宽为23.8%)实现双极化,最大增益可达到7.3 dBi和7.5 dBi,两个端口间隔离度大于25 dB,具有较宽的带宽和良好端口隔离度。更多还原

【Abstract】 A dual-polarized magneto-electric dipole for 5 G millimeter wave applications is proposed in this paper.The magneto-electric dipole consists of four shorted patches and feed networks.The four patches are directly fed by metalized through vias.The feed networks of dual polarizations are designed on the same layer,and the port isolation is improved by differential feeding structure.According to the simulation results,the antenna can realize dual polarization from 23.3～29.6 GHz(the relative bandwidth is 23.8 %),maxgain up to 7.3 dBi and 7.5 dBi,port isolation higher than 25 dB.The magneto-electric dipole has wide bandwidth and good port isolation.更多还原
