摘　　要：为了分析应用于5G大规模天线阵列中的微带辐射的单元的性能,对馈电方式和结构进行研究,设计了一种多点渐变馈电的微带辐射单元。根据微带天线的特点,通过采用耦合、四点馈电方式,并且馈电方式利用渐变式结构,使得阻抗有一个渐变的过程,从而达到增加带宽、提高隔离度的效果。最后利用一个小型天线阵列对辐射单元间性能进行了实测验证,结果证明辐射单元性能均达到预期效果,所设计的辐射单元具有小型化、重量轻和隔离度高的特点,可应用于5G大规模天线阵列天线中。In order to analyze the performance of microstrip radiation element applied in 5G large-scale antenna array,the feeding mode and structure are studied,and a microstrip radiation element is designed based on the multi-point gradual feed mode.According to the characteristics of the microstrip antenna,the impedance has a gradual changing process by adopting coupling and four-point feeding mode and the gradual change structure in the feeding mode.Therefore,the bandwidth is increased and the isolation degree is improved.Finally,a small antenna array is used to test and verify the performance of the radiation elements,and the results show that the performance of the radiation elements achieves the expected results.In addition,the designed radiation element has the characteristics of miniaturization,light weight,and high isolation,and thus can be applied to 5G large-scale antenna array antennas.
