摘要

高增益微带天线阵列的一个主要限制是其高损耗，主要是由于馈电网络。本文介绍了一种具有低损耗、低成本和低轮廓nrd馈电网络的24GHz微带阵列天线的设计和结果。平面结构与nrd导向进给网络之间的互连是通过槽耦合实现的。该天线的馈电网络以nrd -导轨的形式实现，但在后期阶段，可能会以衬底集成(SI) nrd -导轨的形式实现[1]，从而降低生产成本。

A 24 GHz microstrip antenna array with a non-radiative dielectric waveguide (NRD-guide) feeding network

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.
