It is well known that for linear array antennas with isotropic elements, the directive gain depends upon the spacing between the elements. However, this relationship is not as well documented for planar arrays or arrays with medium gain elements, such as micro‐strip patches, particularly in scanned cases. In this article, linear, rectangular, and hexagonal arrays with both isotropic elements and medium gain elements are examined. © 1993 John Wiley & sons, Inc.
