Abstract

This work examines a hemispherical dielectric resonator filtering antenna with broad bandwidth, low profile and improved gain. It is designed with a rectangular slot on the bottom ground plane, below which dielectric laminated and fed by a fifty-ohm microstrip feed line. The proposed structure offers wider bandwidth and better gain because of the higher order mode of hemispherical dielectric resonator. Further a filtering resonator is placed in the feedline to provide two radiation nulls. A complete analysis of the filtering antenna has been thoroughly examined. The design offers a 10 dB impedance bandwidth of 10.7 % ranging from 7.1 to 7.9 GHz having a centre frequency of 7.5 GHz. It offers a reflection coefficient of more than 30 dB at the centre frequency with a flat gain of 7.4 dB in the working band. The value of simulated radiation efficiency is more than 90 % in the working band. After fabricating the suggested structure, the outcomes are contrasted with the values from the simulation. The proposed filtering antenna may fit the 6G frequency band well.

用于6G应用的高增益介质谐振器滤波天线

本文研究了一种具有宽带宽、低轮廓和改进增益的半球形介质谐振器滤波天线。它被设计成在底部接平面上有一个矩形槽，在其下方层压电介质并由50欧姆微带馈线馈电。由于半球形介质谐振腔的高阶模式，该结构提供了更宽的带宽和更好的增益。此外，在馈线中放置滤波谐振器以提供两个辐射零点。对滤波天线进行了全面的分析。该设计提供10.7%的10 dB阻抗带宽，范围为7.1至7.9 GHz，中心频率为7.5 GHz。它在中心频率处的反射系数超过30 dB，在工作频带内的平坦增益为7.4 dB。在工作波段，模拟辐射效率值大于90%。在制作了建议的结构后，将结果与仿真值进行了对比。该滤波天线可以很好地适应6G频段。
