摘　　要：基站天线的设计趋于覆盖多模态频段的宽带模式。传统的宽带天线在实现覆盖大带宽的基础上,其增益却在工作带宽内平坦度变化较大。磁电偶极子天线在覆盖大带宽的同时可保证实现稳定的增益。本文设计了一款应用于3G/4G/5G的多模态宽带的双极化磁电偶极子天线,带宽为1.8 GHz~5.0 GHz,其相对带宽大于94.1%。天线增益在工作带宽内均值大于9 dBi,峰值增益为10.5dBi,增益平坦度变化较为平缓,且天线结构简单。The design of base station antenna tends to cover the broadband mode of multi-mode frequency band. Traditional broadband antennas have achieved large bandwidth coverage, but their gain has a large change in flatness within the working bandwidth. The magneto-electric dipole antenna can ensure stable gain while covering a large bandwidth. A broadband dual-polarized magneto-electric dipole antenna with multi-mode frequency bands that can be applied for 3 G/4 G/5 G was designed. Its bandwidth is 1.8 GHz~5 GHz, and its relative bandwidth is greater than 94.1%. The average value of the antenna gain in the working bandwidth is greater than 9 dBi, the peak gain is 10.5 dBi, the gain flatness changes relatively smoothly, and the antenna structure is simple.
