本文讨论了D波段介质杆天线的设计，它可用作介质透镜天线的馈源。这种馈电取代了在这些频率下难以制造的金属波纹/双模喇叭。为了达到低旁瓣电平，对介质棒进行了锥形化。利用三维电磁仿真软件HFSS（High Frequency Structure Simulator）对天线进行了仿真。所设计的天线具有对称的方位角和仰角波束宽度，并具有很低的交叉极化。仿真结果与设计参数吻合良好。
The paper discusses the design of dielectric rod antenna at D band which can be used as a feed for dielectric lens antennas. This feed replaces the metallic corrugated / dual mode horns which are difficult to fabricate at these frequencies. Tapering of dielectric rod has been done to achieve low side lobe level. The designed antenna has been simulated on 3D EM software HFSS (high frequency structure simulator). The designed antenna has symmetrical azimuth and elevation beam width and having very low cross polarization. The simulated results show very good agreement with the designed parameters.
