Abstract

The flexibility of printed technology offers the possibility of innovative radiating structures well suited to various system requirements. Different systems often need specific radiation patterns such as shaped, directive mono or multibeam with prescribed relative level and positions of lobes, or on the contrary omnidirectional radiation in azimuth; both a large bandwidth and directive patterns are more common requirements for communication systems. Research in the University of Rennes I Laboratory has focused on the corner fed square patch and the array design of such elements. Both planar and cylindrical structures have been investigated and some results are reported here. The properties of the corner fed patch are first given and four examples of arrays and applications are presented: dual beam Doppler radar for accurate measurements of speed and shaped beam for radio distribution (Bognais, 1986) (with sector and cosecant square patterns), omnidirectional cylindrical array for search and rescue maritime systems, and large bandwidth planar directive array.

印刷天线阵列:商业应用的例子

印刷技术的灵活性提供了创新的辐射结构的可能性，非常适合各种系统的要求。不同的系统通常需要特定的辐射模式，如具有规定的相对水平和波瓣位置的形状、定向单波束或多波束，或者相反，在方位角上的全向辐射;大带宽和指令模式都是通信系统更常见的需求。雷恩大学第一实验室的研究重点是角馈电方形贴片和此类元件的阵列设计。本文对平面结构和圆柱结构进行了研究，并报道了一些结果。首先给出了角馈电贴片的特性，并给出了四种阵列和应用实例:用于精确测量速度的双波束多普勒雷达和用于无线电分布的形波束(Bognais, 1986)(具有扇形和正割方形模式)，用于海上搜索和救援系统的全向圆柱形阵列，以及大带宽平面定向阵列。
