Focusing Characteristics of Symmetrically Configured Bootlace Lenses.
Abstract
The line-source bootlace lens, produces optimum focusing characteristics when it is constrained to exhibit front-to-back as well as right-left symmetry. It is shown that the symmetric bootlace lens is a one-parameter family when the radiating array is specified to be lambda/2 spaced with + or - 90-degree coverage. Design equations for the lens are derived, and overall focusing performance and design data are plotted. A computer program of the design equations is presented.
