Abstract

Printed patch element are attractive from the electromagnetic point of view, however, their practical use often calls for involvement of layered composite panels. With such approach, patch elements can sustain mechanical loads or be integrated with antenna array carrying platforms. Owing to a lightweight multilayer structure with a thin substrate atop the thick one, the three-strip couplers put a lot of comfort in design of such antenna arrays. Wideband operation and low losses attract further attention to this coupler type as a good candidate for uses in antenna arrays. Dimensioning of the couplers are convenient for practical utilization in lower microwave bands. Furthermore, three-strip couplers make possible switching signals between printed circuit layers.
轻型L波段和s波段天线,由三带定向耦合器馈电
从电磁的角度来看,印刷贴片元件是有吸引力的,然而,它们的实际应用往往需要分层复合面板的参与。通过这种方法,贴片元件可以承受机械载荷或与天线阵列承载平台集成。由于三带耦合器是一种轻量化的多层结构,在厚衬底上加薄衬底,这给这种天线阵列的设计带来了很大的舒适性。宽带操作和低损耗吸引了人们对这种耦合器类型的进一步关注,因为它是天线阵列中使用的良好候选者。该耦合器的尺寸便于在较低微波波段的实际应用。此外,三带耦合器使得在印刷电路层之间切换信号成为可能。
