An array of low profile horns fed by transverse slots on a groove gap waveguide (GGWG) is presented. The GGWG is implemented with glide symmetrical holes and the design frequency is 28 GHz. The low profile horns are integrated in the same waveguide wall as the slots. The designed antenna is a linear array of these horns but the solution can be easily extended to a planar array. Experimental results support this work. The designed antenna is a good candidate for applications related to 5G technologies where medium to high gains as well as high efficiencies are required and reasonable manufacturing costs are demanded.

横向缝隙槽隙波导以28 GHz频率馈电的喇叭阵列。

提出了由槽隙波导（GGWG）上的横向狭缝馈入的低轮廓喇叭阵列。GGWG采用滑行对称孔实现，设计频率为28 GHz。低矮的喇叭与槽缝集成在同一波导壁中。设计的天线是这些号角的线性阵列，但解决方案可以轻松扩展到平面阵列。实验结果支持这项工作。设计的天线非常适合与5G技术相关的应用，这些应用需要中等至高增益以及高效率，并需要合理的制造成本。
