摘　　要：为了满足无线通信领域的需求,构建了一种新型宽带双极化磁电偶极子天线。该天线包括4片水平排列的电偶极子和8块垂直排列的磁偶极子,采用正交Γ型馈电连接同轴激发。设计中采用了电偶极子上的槽隙来增加带宽,在天线顶部加装引向器以稳定带宽和提升带内增益。经过HFSS电磁仿真软件测试验证,该天线在|S_(11)|<-10 dB时具有89%的阻抗带宽(0.91~2.25 GHz),-3 dB增益带宽保持在75%,带内最大增益可达到14.45 dBi。所提天线带宽较宽,能够缓解双极化基站天线频带利用不足的问题,有一定的应用前景。A novel broadband dual-polarized magneto electric dipole antenna is constructed to meet the needs of today's wireless communication field.The antenna consists of four horizontally aligned electric dipoles and eight vertically aligned magnetic dipoles with orthogonalΓ-type feed connections for coaxial excitation.A slot gap on the electric dipoles is used in the design to increase the bandwidth and a director is added at the top of the antenna to stabilize the bandwidth and enhance the in-band gain.As verified by HFSS electromagnetic simulation software,the antenna has 89%impedance bandwidth(0.91 GHz to 2.25 GHz)at|S_(11)|<-10 dB,the-3 dB gain bandwidth is maintained at 75%,and the maximum in-band gain can reach 14.45 dBi.This antenna has a wider bandwidth and can alleviate the problem of underutilization of the bandwidth of dual-polarized base station antennas,and thus has certain application prospects.
