摘　　要：为实现天线的小型化和多频段频率特性,提出了一种双频混合圆柱形介质谐振器天线。该天线将圆形铜带加载到介质谐振器天线的顶部,可以在4.4 GHz和6.1 GHz处谐振,并且-10 dB带宽分别为600 MHz和500 MHz。使用了矩形槽激励圆柱介质谐振器的HEM_(11)模,并通过调整寄生条带宽度和间隙来控制多个较高频段。实验结果表明,该天线具有良好的增益(4.4 GHz时为4.9 dBi,6.1 GHz时为5.6 dBi)、效率高(所有工作频段均大于88%)和良好的天线前后比(两个主平面上均大于10.08 dB),可有效适用于5G和WiFi融合组网。In order to realize the miniaturization and multi-band frequency characteristics of the antenna,a dual-band hybrid cylindrical dielectric resonator antenna is proposed.The antenna loads a round copper strip on the top of the dielectric resonator antenna,which can resonate at 4.4 GHz and 6.1 GHz,and the-10 dB bandwidth is 600 MHz and 500 MHz respectively.The rectangular slot is used to excite the HEM_(11) mode of the cylindrical dielectric resonator,and several higher frequency bands are controlled by adjusting the parasitic strip width and gap.Experimental results show that the antenna has good gain(4.9 dBi at 4.4 GHz and 5.6 dBi at 6.1 GHz),high efficiency(higher than 88%in all operating frequency bands)and good front-to-back ratio(larger than 10.08 dB in both main planes),which can be effectively applied to 5 G and WiFi convergence networking.
