A Lightweight Constrained Lens for Wide Angle Scan in Two Planes,
Abstract
A new design principle has been used to construct a three-dimensional constrained lens whose planar front and back faces are arrays of microstrip patches. The two arrays face in opposite directions and have a common ground plane. Each back face element is connected to a front face element by a short length of microstrip line and a feed-thru hole in the ground plane. The lengths of those transmission lines is a function of radius, with the longest in the center. Wide-angle focusing is achieved by the addition of a second geometric degree of freedom - the back face elements are not directly behind their corresponding front face elements, but are displaced radially, with the amount of displacement also varying as a function of radius.
