本文介绍了射电天文学和其他应用的高性能紧凑型孔径阵列天线的设计。本文研究了平方公里天线阵设计研究（SKADS）中的三种最新天线发展，并对它们的性能进行了比较。除了射频（RF）性能之外，平方公里阵列应用的一个基本要求是每平方面积的成本。基于最初的大规模有限阵列研究的原型具有不同的几何形状已经制造和测量。在低交叉极化和宽扫描角的应用中，大规模宽带双极化阵列设计的指导方针。
This paper describes the design of high performance compact aperture array antennas for radio astronomy and other applications. Three recent antenna developments for Square Kilometre Array Design Study (SKADS) have been investigated and the performance are compared. In addition to the Radio Frequency (RF) performance, an essential requirement for the Square Kilometre Array application is the cost per square area. Based on initial large scale finite array studies prototypes with different geometries have been fabricated and measured. Guidelines are derived for large scale wide band dual-polarized array designs in applications where low cross polarization and wide range of scan angles are required.
