高增益微带天线阵的一个主要限制是其高损耗，主要是由于馈电网络。本文介绍了一种低损耗、低成本、低剖面NRD波导馈电网络的24GHz微带阵列天线的设计和结果。平面结构与NRD波导馈电网络之间的互连通过缝隙耦合实现。该天线的馈电网络被实现为NRD波导，但在稍后的阶段，它可能被实现为具有更低生产成本的基板集成（SI）NRD波导[1]。
A major restriction of high gain microstrip antenna arrays is found in their high losses, mainly due to the feeding network. In this contribution, design and results of a 24GHz microstrip array antenna with low loss, low cost and low profile NRD-guide feeding network are presented. Interconects between planar structures and NRD-guide feeding network are done by slot coupling. The feeding network for this antenna was implemented as NRD-guides, but in a later phase, it might be implemented as substrate integrated (SI) NRD-guides [1] with even lower production cost.
